The pH was maintained at 10. 0 M sodium carbonate. The invention additionally provides sets of pre-labeled protein standards that can be used as molecular weight markers in biochemical separations, in which at least one labeled protein of the sets is selectively labeled on a first amino acid. Novex sharp prestained protein standard.html. The ligation reaction was transformed into One Shot® Top 10 competent bacterial cells (Invitrogen, Carlsbad Calif., USA) and the resulting colonies were PCR screened for the LacZ gene. In order to provide a clear and consistent understanding of the specification and claims, including the scope to be given such terms, the following definitions are provided.
The dye was purified using a reverse phase column. The dye fractions were combined and the solvent was removed in vacuo using a rotary evaporator. Novex sharp prestained protein standard dual. In any of these examples an N-terminal amino acid, which can be labeled on the N-terminal amino group, can be a target amino acid or a non-target amino acid. In certain illustrative examples, the non-target amino acid is capable of reacting with the label more efficiently than any other amino acid in the protein, except for the first amino acid. 5, 30% glycerol, 2% SDS, and 2.
42 residues of target amino acid/kDa for a second protein of a standard set, where the first and second proteins have ratios of the number of target amino acid residues to molecular weight that are within 5% of one another. The pre-labeled protein standards of the present invention are particularly useful in gel electrophoresis, in which molecular weights can be determined using the pre-labeled standards run alongside one or more sample proteins. In some embodiments, the molecular weight increment, +/−1 kDa, is a multiple of a value between 5 kDa, a multiple of a value between 10 kDa, a multiple of a value between 20 kDa, or a multiple of 50 kDa. Novex sharp prestained protein standard mix. 150 mls of the seed flask culture is then transferred to a 7 liter fermentor that contains 5 liters of rich media made as for the seed culture. Although reaction conditions can be adjusted to reduce side reactions with one or more amino acids that are not targeted for labeling, side reactions are difficult to completely eliminate or control. 7 kd) and the remaining five identical repeats were set at 258 bp (each providing a translation product of 9. As used herein, the terms "about" or "approximately" when referring to any numerical value are intended to mean a value of ±10% of the stated value. Pre-Labeled Protein Standard Kits.
An amino acid sequence derived from the sequence of a naturally-occurring protein preferably has at least 70%, at least 80%, at least 90%, or at least 95% amino acid identity with at least twenty, at least thirty, at least forty, at least fifty, at least sixty, at least seventy, or at least eighty contiguous amino acids of the naturally occurring protein. Blue Protein Standard, Broad Range, New England Biolabs. Separation methods that are commonly performed in biochemistry for the purification, identification, and characterization of proteins include chromatography, gel electrophoresis, and solution electrophoresis. The diazonium salt should not be allowed to dry out. 3 colors: Pink, Yellow, Blue|.
Selectivity of labeling is best obtained by selection of an appropriate reactive dye. Electrophoretic Migration. The dried dye vinyl sulfone precursor was dissolved in 50 mL of water and transferred to a 100-200 mL round bottom flask equipped with a stir bar. All gels were 8×8 cm "mini" gels from Invitrogen, Carlsbad, Calif., and electrophoresis conditions were those provided by the manufacturer. 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. 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. In the context of the present invention, "selectively labeled" means labeled predominantly on particular sites of a biomolecule. 4 residues of first amino acid/kDa for a first protein of a standard set, and can be, for example, between 0. The resin-bound dye was then washed to remove most of the acid from the coupling step. In some embodiments, a non-target amino acid has a different reactive group from the target amino acid.
Provisional Application 60/870, 252 filed Dec. 15, 2006 and to U. The sample is centrifuged at 8, 000×g for 10 minutes to remove any insoluble particles. 1 forward primer (SEQ ID NO:20) and 50. In some embodiments, a selectively labeled protein of the invention lacks residues of a second amino acid that can react with a labeling compound. Population genetic and biophysical evidences reveal that purifying selection shapes the genetic landscape of Plasmodium falciparum RH ligands in Chhattisgarh and West Bengal, India. 100 μl of 60 kDa BenchMark™ stock solution (OD=3. In some preferred embodiments, the method further comprises determining the molecular weight of the one or more sample proteins. The protein ladder is supplied in gel loading buffer and is ready to use. Isoleucines at positions 23 and 45 were changed to arginine to decrease the protein's predicted hydrophobicity. XhoI-SpeI-XbaI-BgLII-50 kd-NheI-BamHI-PstI.
Add 40 ml 1M sodium phosphate pH=7. The invention provides pre-labeled protein standard sets that comprise a plurality of labeled proteins, in which two or more of the labeled proteins are selectively labeled on a first amino acid with a labeling compound and lack residues of a second amino acid that is capable of reacting with the labeling compound, in which the ratios of the number of residues of the first amino acid to molecular weight of the two or more selectively labeled proteins are within 5%, 2. White colonies were selected for colony PCR screening using the specific primer sets used in the cloning. 5 mg/ml solution of the 260 kDa standard protein. 1% SDS in 50 mM Tris pH=8. A "chromophore" is a chemical group or compound capable of selective light absorption resulting in the coloration of the organic compound. One aspect of the invention is a protein labeled on cysteine. Where multiple dyes are used to label proteins of a pre-labeled protein standard set, one, two, three, four, or more pre-labeled proteins of the set can be labeled with the same dye. The solution was then cooled back to 0° C. to precipitate the diazonium salt. Protein Concentration. The protein solution plus TCA is incubated at 4° C. for 1-2 hours and then centrifuged at 8, 000×g for 10 minutes at 4° C. The liquid is discarded and 30 ml of ultrapure H2O is added and mixed well.
Cysteine and methionine at positions 35 and 37 were replaced with arginine and cysteine to increase the distance between cysteine residues and minimize the potential steric hindrance created by two dye molecules binding to cysteines residues at positions 34 and 37. A dye can be tested for suitability in labeling a protein for use as a standard by labeling a protein with the dye to be tested on a target amino acid, in which at least one non-target amino acid of the protein is depleted in the protein, and performing a separation procedure on the labeled protein and the protein in unlabeled form, detecting the labeled and unlabeled protein after the separation procedure is completed, and comparing the separation of the labeled and unlabeled protein. The column volume was at least ten times the sample volume. A "nontarget amino acid" can have the same reactive chemical group as a target amino acid or a different reactive chemical group. Fractions of 10 ml were collected and aliquots were run on a gel, and the purified protein fractions were pooled together. 5 kDa range in width from 0. 6A shows a map of the pTrc BH 50 kDa "No Lysine" construct. 15C shows a 4-20% Tris-glycine gel on which a set of pre-labeled protein standards (Sharp Pre-stained Standard; lane 4) were electrophoresed alongside other commercially available pre-stained markers: 1—Precision Plus Blue (Bio-Rad); 2—Precision Plus Dual (Bio-Rad); 3—Precision Plus Kaleidoscope (Bio-Rad); 4—Sharp Pre-stained Standard (Invitrogen); 5—Rainbow (GE); 6—BenchMark™ prestain (Invitrogen); 7—MultiMark (Invitrogen); 8—SeeBlue+2 (Invitrogen). A nucleic acid sequence derived from the sequence of a naturally-occurring nucleic acid can be referred to as a "naturally-occurring nucleic acid-derived nucleic acid sequence" or, simply, "a derived [nucleic acid] sequence".
Labeled proteins were denatured and reduced with the addition of 25 μl of 20% SDS and 10 μl 400 mM TBP per 1 ml of protein conjugate with an incubation of 30 minutes at room temperature.
