913, where C is concentration (mg/ml); A is absorbance at 280 nm; and D is dilution. Storage bufferpH: 7. A selectively labeled protein that is comprises sequence not derived from a naturally-occurring protein can in some preferred embodiments lack residues of a non-target amino acid. In another example, glutamate, aspartate, and the C-terminal amino acid of a protein can be target amino acids, where a dye conjugated to the selectively labeled protein includes a reactive chemical group that reacts with carboxylates. A dark color developed immediately. The data was loaded in Excel and the number of image units per 1 mm was calculated by dividing the length of the gel by the total number of image units for this length: Running length of the gel=68 mm; Length in image units=850−44=806; Number of image units per 1 mm=806/68=11. 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. Reactive groups generally include without limitation nucleophiles, electrophiles and photoactivatable groups. Similarly, "about 100 mM" (or "approximately 100 mM") encompasses a range of concentrations from 90 mM to 110 mM, inclusive.

Provisional Application 60/820, 101 filed Jul. 4 ml 8M urea, 20 mM phosphate, 500 mM NaCl pH=7. In other embodiments of a pre-labeled protein standard, the target amino acid is cysteine and a second amino acid is lysine. The variance in pH of alternative buffers affects the charge of the labelled protein standard and its binding capacity for SDS. In some preferred methods of labeling cysteine residues, the reducing agent is beta-mercaptoethanol, dithiothreitol, TCEP, or TBP. Sequences depleted in a non-target amino acid can be further selected based on the frequency of the target amino acid, e. g., cysteine. Large scale cultures can be grown in a 7 L fermentor (e. g., an Applikon fermentor) through which air is bubbled. 5%, or 1% of one another. Electrophoretic Migration. A selectively labeled protein can have more than one non-target amino acid.

In creating a six Thio repeat construct, the first of six Thio repeats of pTrcBH 60 kd was set at 208 bp (providing a translation product of 7. Fractions of 10 ml were collected and aliquots were run on a gel, and the purified protein fractions were pooled together. In the context of the present application, a "target amino acid" or "an amino acid targeted for labeling" is an amino acid that is used for the covalent attachment of a label, such as a dye, to a peptide or protein. The bovine insulin b-chain was purified by reduction of bovine pancreas insulin (Sigma-Aldrich, St. Louis, Mo., USA) at denaturing conditions and then separation of the b-chain on an ion exchange column. 8-anilino-1-naphthalenesulfonic acid (8-ANS) was prepared by placing the solid in a 250 mL round bottom flask equipped with a stir bar. 21, 2007 and having a size of 87. Isoleucines at positions 23 and 45 were changed to arginine to decrease the protein's predicted hydrophobicity. Reducing or eliminating the attachment of a dye to residues of one or more amino acids not targeted for labeling decreases variability in the amount and position of dye attached to a marker protein. In another embodiment, the method includes: providing a pre-labeled protein standard set to a customer, in which two or more of the labeled proteins of the standard set is selectively labeled on a first amino acid and at least two of the two or more selectively labeled proteins have a constant ratio of a first amino acid to molecular weight, in exchange for revenue. PGRMC1 phosphorylation affects cell shape, motility, glycolysis, mitochondrial form and function, and tumor growth.
A "recombinant protein" is a protein made from a recombinant nucleic acid molecule or construct. BRIEF DESCRIPTION OF THE DRAWINGS. 3 µl or 5 µl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively. In some embodiments, a selectively labeled protein is labeled on a first amino acid and includes an amino acid sequence having at least 80% homology to at least 40 contiguous amino acids of a naturally-occurring protein, in which the sequence having homology to the naturally-occurring protein has fewer residues of a second amino acid than the sequence of the naturally-occurring protein to which it is homologous. For example, the method in some embodiments includes attaching a label that includes a sulfhydryl-reactive group, such as but not limited to a vinyl sulfone, an iodoacetamide, an maleimide, a disulfide, a mercurial compound, a haloacetyl compound, or an iodoacetic acid, to a protein that is depleted in lysine residues. The appropriate amount of compound for any protein or other component is conveniently predetermined by experimentation in which variable amounts of the compound are added to the protein, the conjugate is purified (for example, using chromatography) to separate unconjugated compound and the protein-labeling compound conjugate is tested in its desired application. In targeting an amino acid for labeling, a labeling compound is selected that has a reactive group that specifically reacts with the reactive group of the target amino acid to form a covalent bond, thereby forming a labeling compound-protein conjugate, or labeled protein. The present invention provides pre-labeled protein standard sets that when electrophoresed give sharp bands that have migration distances consistent with the migration distances of the proteins of the standard set electrophoresed in unlabeled form. The sample is left to cool down to room temperature.
