Lane 2: Novex Sharp 10µl. 5 kDa (such as, for example, having a molecular weight of greater than 5 kDa, such as, for example, having a molecular weight of 10 kDa or greater) have substantially the same migration on electrophoresis gels as their unlabeled counterparts. All 7 lysine (K) amino acids were changed to arginine (R) at positions 4, 19, 52, 70, 83 and methionine (M) at position 36 to favor the binding of the dye molecules to cysteine rather than lysine. Novex sharp prestained protein standard chartered. Insulin and lysozyme were labeled at the concentrations described in the corresponding protocols. The liquid fraction was discarded and the pellet (insoluble fraction) was resuspended in 50 μl of 1×LDS Sample buffer. This product was previously called Prism Ultra Protein Ladder (10-245 kDa). The invention includes pre-labeled protein standard sets that comprise a plurality of labeled proteins, in which one or more of the labeled proteins is depleted in lysine residues and comprises a labeling compound conjugated to one or more cysteine residues. The solution became clear and was cooled to room temperature. Illustrative biological examples include urine, sera, blood plasma, total blood, saliva, tear fluid, cerebrospinal fluid, secretory fluids from nipples and the like.
The invention also includes a set of pre-labeled protein standards that comprises a plurality of labeled proteins, in which one or more of the labeled proteins is selectively labeled on a first amino acid, in which the plurality of labeled proteins are provided in one or more solutions. Recombinant methods also includes methods of introducing nucleic acids into cells, including transformation, viral transfection, etc. 3 µl or 5 µl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively.
Mass spectrometry analysis of the actual molecular weight of the expressed protein revealed that it was 10 kDa larger than expected (Table 4). With the solution is stirring, sodium hydroxide was added dropwise to the stirred the solution until the pH is 10. The solution was then cooled back to 0° C. Blue Protein Standard, Broad Range, New England Biolabs. to precipitate the diazonium salt. Convenient - a ready-to-use formulation eliminates the need to heat, reduce, or add sample buffer prior to use.
1B) that was modified to contain 4 cysteine (C) and no lysine (K) amino acids. In a further aspect, methods are provided for characterizing one or more sample proteins using a pre-labeled protein standard set provided herein. This clone was subsequently designated pTrc 260 kDa (FIG. In some preferred embodiments, an amino acid sequence derived from a thioredoxin sequence differs from the naturally-occurring thioredoxin sequence by lacking lysine residues. In some embodiments, one or more codons of the second amino acids is deleted from the nucleic acid sequence to delete amino acid residues from a standard protein that are capable of reacting with a labeling compound. In some embodiments, mutation of a codon results in a conservative amino acid change in the amino acid sequence of the protein. Novex sharp prestained protein standard curve. 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. 9), a truncated LacZ gene encoding a 100 kDa polypeptide (SEQ ID NO:40; FIG. Population genetic and biophysical evidences reveal that purifying selection shapes the genetic landscape of Plasmodium falciparum RH ligands in Chhattisgarh and West Bengal, India.
After two hours the pH was adjusted back to neutrality using 1 M HCl. 6A shows a map of the pTrc BH 50 kDa "No Lysine" construct. 7 kd) and the remaining five identical repeats were set at 258 bp (each providing a translation product of 9. Provided herein are labeled protein standards useful in electrophoresis or chromatography that have consistent separation characteristics that are substantially the same as the separation characteristics of their unlabeled counterparts. 3 kDa and about 1 kDa, or between about 0. Unambiguous - each band in the standard is pre-stained with a unique color for easy interpretation of results. PTrc 260 kd Expression Vector: A 260 kDa protein expression vector, pTrc 160+LacZ, was also constructed. In some embodiments, the invention provides pre-labeled molecular weight standard sets in which three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, or more of the labeled proteins of the set differ in size from one another by molecular weight increments that are multiples of 5 kDa, 10 kDa, 20 kDa, or 50 kDa. The width of each peak at half height was therefore divided by 11. Nucleic acid sequences in the genome can be chromosomal or extra-chromosomal (for example, the nucleic acid sequences can be episomal or of an organelle genome). The sample concentration is determined visually or using the Alpha Imager 3000 with quantitation software (Alpha Innotech, San Leandro, Calif., USA).
The BH6mer ORF was ligated into the digested pTrc vector backbone via BamHI-PmeI to generate the pTrc BH 60 kd expression construct having the insert shown in FIG. A vector, protein-encoding sequences, etc. Pre-labeled protein standards for electrophoresis are notoriously less sharply resolving than unlabeled standards, and often the molecular weights of the labeled markers are inexact, differing from the unlabeled proteins by varying amounts. Another factor contributing to poor resolution of pre-labeled proteins on electrophoresis gels is protein-to-protein variability in the ratio of the number of attached dye molecules to molecular weight. Insert Configuration. Any of the amino acids cysteine, lysine, histidine, tryptophan, aspartate, glutamate, methionine, tyrosine, or asparagine can also be a non-target amino acid whose interaction with a labeling compound is sought to be reduced or eliminated when a protein is labeled on a first amino acid. 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 sample may also include diluents, buffers, detergents, and contaminating species, debris and the like that are found mixed with the target. The LacZ gene was generated with Platinum® PCR Supermix High Fidelity PCR mix (Invitrogen; Carlsbad, Calif. ) using primers capped with Avr II restriction sites. The bottle was purged with argon and labeled with the following name to distinguish it from the starting material: "Reactive Orange 16 Vinyl Sulfone". The pH was maintained at 10. The expression clone was labeled pTrc 50.
A) combining a protein that comprises a first amino acid that comprises a first reactive group with a labeling compound that comprises a second reactive group that reacts with the first reactive group, to form a protein-labeling compound mixture; and, - b) incubating the protein-labeling compound mixture for a sufficient amount of time for the labeling compound to form a covalent bond with first reactive group of the first amino acid, wherein a labeled protein standard is formed.
