The resin-bound dye was then washed to remove most of the acid from the coupling step. 11A shows a map of pTrc 260 kd. Review other protein ladders in the unstained and prestained protein ladder guide. This design allowed for the subcloning of this ORF, referred to a BH6mer ORF (SEQ ID NO:13, FIG. In some preferred embodiments, the proteins having ratios of first amino acid to molecular weight within 10%, 5%, 2. The mutation of codons can be to any non-target codon and need not be restricted to conservative mutation. Novex sharp prestained protein standard mix. In some preferred embodiments, the labeled proteins of a pre-labeled protein standard set having molecular weights between 20 kDa and 100 kDa produce visually detectable bands on electrophoresis gels having widths that do not differ by more than 50%. The protein(s) selectively labeled on cysteine can comprise an amino acid sequence that is not homologous to a known amino acid sequence of a naturally-occurring protein, or can be an amino acid sequence that has homology to the sequence of a naturally-occurring protein. In some illustrative embodiments of pre-labeled protein standard sets, one or more selectively labeled protein standards of the set comprises a naturally-occurring protein, or a fragment thereof, that is labeled on a first (target) amino acid and that lacks a second (non-target) amino acid.
In exemplary embodiments, the selectively labeled protein lacks residues of a non-target amino acid capable of reacting with the dye. The following examples are intended to illustrate but not limit the invention. 5A), and pTrc BH 50 kDa construct (shown in FIG. 1% SDS and then the sample was loaded. In some preferred embodiments of the invention, a protein used as a pre-labeled molecular weight standard includes one or more copies of an amino acid sequence derived from a bacterial thioredoxin sequence, such as an E. Novex sharp prestained protein standard range. coli thioredoxin sequence, and can be a low molecular weight thioredoxin, such as a sequence encoded by TrxA. The volume of the column was at least 20 times the volume of the sample for proteins labeled with the Red (8-ANS-APVS) dye.
In some preferred embodiments, the set of pre-labeled protein standards comprises two or more labeled proteins that comprise two or more copies of a sequence derived from a naturally-occurring protein, in which the two or more labeled proteins lack lysine residues and are labeled on at least one cysteine residue. 9), a truncated LacZ gene encoding a 100 kDa polypeptide (SEQ ID NO:40; FIG. In some preferred embodiments, the two or more labeled proteins that have a consistent ratio of the number of residues of a first, or target, amino acid to molecular weight of the proteins are selectively labeled on a first amino acid. A pre-labeled standard set include 5 proteins labeled with at least four different dyes of different colors, in which the width of bands visible to the naked eye of the electrophoresed proteins difference by 3% or less. The sample is left to cool down to room temperature. D) incubating the protein with the reducing agent for a sufficient amount of time for cysteine-cysteine bonds to be reduced. Blue Protein Standard, Broad Range, New England Biolabs. The sample was vortexed to resuspend the cells and incubated for 10 minutes at room temperature. Capping of Labeled Proteins. A "nontarget amino acid" is an amino acid on a protein standard that has a reactive group that is capable of reacting with a labeling compound conjugated to a target amino acid of the protein standard, but whose conjugation to a labeling compound is not desired. Alkylation is performed at a protein concentration of 1 mg/ml. For Research Use Only. The invention also includes methods for separating two or more protein standards of a set of pre-labeled protein standards, in which the pre-labeled protein standard set includes at least one protein that is selectively labeled on a first amino acid and is depleted in residues of a second amino acid. It was converted to the vinyl sulfone in order to react with the sulfhydryls of proteins for generating dyed marker proteins. This mixture was added to an addition funnel and placed on top of the flask containing the 4-aminophenyl-2-sulfonatoethyl sulfone.
A "dye" is a visually detectable label. 10) was cloned into the AvrII site. Novex sharp prestained protein ladder. 16B depicts a trace extracted from the gel image having peaks 2-13 corresponding to band intensity of the pre-labeled proteins. Preferably, a labeling compound is a dye detectable with the naked eye such that labeled proteins can be detected in a gel immediately after, and preferably during, electrophoresis without the need for additional processing or image analysis of the gel. 14B shows the same set of markers in unlabeled form electrophoresed on a 4-12% Bis-Tris gel with MES running buffer.
2 using a calibrated pH meter. 1B depicts the translated amino acid sequence of truncated E. coli bacterial thioredoxin having a C-terminal his tag on line 2 (SEQ ID NO:11) aligned with the same sequence in which all of the lysines have been changed to arginines and two cysteines have been added on line 1 (SEQ ID NO:12). The standards can be labeled with two, three, four, or more visually distinguishable dyes. Bound a-chain was eluted with 8M urea in 50 mM Na-acetate, 500 mM NaCl pH=5. A set of pre-labeled protein standards can comprise two or more labeled proteins, in which the two or more proteins comprise different numbers of copies of a sequence derived from a naturally-occurring protein, in which the number of residues of a non-target amino acid have been reduced relative to the naturally-occurring protein sequence. The soluble fraction is discarded. Labeling of proteins is typically performed by attaching a label to a chemical group of one or more amino acid residues of the protein. For example, the sulfhydryl group of cysteine is generally a stronger nucleophile than the amino groups of lysine, the N-terminus of a protein, histidine, and tryptophan, which are stronger nucleophiles than the carboxyl groups of the C-terminus of a protein, aspartic acid, and glutamic acid, and the phenolate of tyrosine. Codons of a target amino acid can be deleted, inserted, or mutated to codons of other amino acids, for example to provide proteins for labeling that include more than one target amino acid per 10 kDa, such as an average of 2, 3, 4, or more target amino acids per 10 kDa. A fluorophore can be excited by visible light or non-visible light (for example, UV light). In some preferred embodiments, the two or more labeled proteins are comprise a labeling compound bound to a first amino acid and comprise one or more copies of an amino acid sequence of or having homology to an amino acid sequence of a naturally-occurring protein, in which the amino acid sequences of the labeled proteins lacks residues of a second amino acid that can react with the labeling compound.
Using the pTrc BH 60 kDa expression construct of Example 1 as the PCR template, several 50 kDa inserts were generated using Platinum® PCR Supermix High Fidelity PCR mix (Invitrogen; Carlsbad, Calif. ) that contained Taq DNA polymerase, Pyrococcus species GB-D thermostable polymerase, Platinum® anti-Taq polymerase antibody, 66 mM Tris-504 (pH 8. In embodiments in which at least one of lysine, histidine, or tryptophan is a target amino acid, a label preferably includes an amino-reactive group for conjugation to the standard. 1 D3 was the base construct used in subsequent subclonings for construction of the pTrc 110 kDa, pTrc 160 kDa, and pTrc 260 kDa expression vectors. The addition of label to a variable number of sites of a particular protein through side reactions reduces the uniformity in the amount of label attached to the protein, such that a given labeled protein standard comprises a population of labeled protein molecules in which different members of the population have different migration characteristics. In some aspects, a pre-labeled protein standard set can include one or more proteins not made by recombinant methods. The term "label" as used herein refers to a chemical moiety or protein that is directly or indirectly detectable (e. g. due to its spectral properties, conformation or activity) when attached to a target or compound and used in the present methods. Textile dyes can also be used to dye materials and compounds other than fabrics and materials for making fabrics. The labeling of all no-lysine (NL) proteins (the 30 kDa, 40 kDa, 50 kDa, 110 kDa, and 160 kDa NL proteins) and the 260 kDa protein was performed at 0. 10 shows the sequence of a truncated Lac Z gene (SEQ ID NO:40) that was used to synthesize the pTrc 260 kd plasmid. The Novex™ Sharp Pre-Stained standard loading buffer consists of 65 mM Tris pH 6. Examples of nucleotide-disulfide oxidoreductases include lipoamide dehydrogenase, glutathione reductase, or thioredoxin.
Such sequences can be fused in any combination with themselves or other sequences to provide protein standards. The PCR inserts were TA cloned into pCR2. For example, a pre-labeled standard is labeled prior to separation of that standard by biochemical techniques such as, but not limited to, electrophoresis (including both solution phase and gel electrophoresis), isoelectric focusing, spectrometry, or chromatography. 5 µl per well for general western transferring. The synthesis scheme is depicted in FIG. The cells are re-suspended in the lysis reagent by vortexing intermittently for 30 minutes at room temperature. 13/715, 812 filed Dec. 14, 2012, now U. Pat. The protein that is selectively labeled can be a naturally-occurring protein that lacks a non-target amino acid and that is isolated from cells, tissue, organisms, biological samples, or media. A "pre-labeled" biomolecule is a biomolecule that includes a label prior to performing a separation or experiment with the biomolecule. CCGGCGGCCGATGTGTGATCGTATTATTCAT, |50. In another embodiment, the method includes: providing a pre-labeled protein standard set to a customer, in which the pre-labeled protein standard set includes 12 or more labeled proteins, in which the migration of each of the labeled protein standards having a molecular weight of 5 kDa or greater is within 5% of the migration of each of the five or more protein standards in unlabeled form on the same acrylamide gels, in exchange for revenue. Comprehensive - a wide range of molecular weight bands consisting of 12 proteins in the range of 3. By reducing the number of residues of amino acids that can bind a labeling compound in side reactions, variability in the amount of labeling compound attached to a given protein molecule is reduced.
11/781, 251 filed Jul. This solution was stirred for 1 hour and then adjusted to pH 7 using 1 N HCl. The bands of a pre-stained protein marker run in a denaturing polyacrylamide gel can be, for example, significantly wider and more diffuse than a band that results from the same protein that has not been pre-labeled, but instead is stained after electrophoresis is complete. A nucleic acid (or nucleotide) or protein (or amino acid) sequence that is "derived from" another nucleic acid (or nucleotide) or protein (or amino acid) sequence is either the same as at least a portion of the sequence it is derived from, or highly homologous to at least a portion of the sequence it is derived from, having at least 65%, 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98%, or 99% identity with the sequence of the protein from which it is derived. For example, to test the consistency of migration between a labeled protein standard and its unlabeled counterpart, electrophoresis can be performed on a polyacrylamide gel, having a length of 8 cm, in which at the end of electrophoresis the dye front of the gel has migrated at least 5 cm, such as at least 6 cm, such as at least 6. 160 and 260 kDa purification. Insulin b-Chain Purification. Different proteins of a pre-labeled protein standard set can be labeled with different dyes having different colors, such that two or more protein bands can be distinguished by color when the proteins of the standard set are separated, such as on a gel. The pre-labeled marker set of Example 11 (10 microliters) was electrophoresed alongside the same set of proteins in unlabeled form (5 microliters) in a 4-12% Bis-Tris (NuPAGE® Novex®) acrylamide gel run with 1×MES buffer. In some embodiments, a protein standard selectively labeled on cysteine comprises one or more copies of an amino acid sequence having homology to an amino acid sequence of a naturally-occurring protein, in which the amino acid sequence homologous to a sequence of a naturally-occurring protein has a reduced number of lysine residues relative to the sequence of the naturally-occurring protein.
