Ab116028 has been referenced in 16 publications. In preferred embodiments, protein standards of the prelabeled standard set having molecular weights of 10 kDa or greater migrate within 5% of the distance of the that the same protein standards in unlabeled form migrate. Background Information. The dye was purified using a reverse phase column. The molecular weight standard set included proteins labeled with four different visually distinguishable dyes.
10 ul of 400 mM tributylphosphine (TBP) was added per every ml of solution (to 4 mM final concentration). For example, a thioredoxin sequence used in a protein standard can have a truncation of from one to 50 amino acids from the carboxy terminus, such as, for example, from one to ten, from ten to twenty, form twenty to thirty, form thirty or forty, or from forty to fifty, amino acids can be truncated from the carboxy terminus. The dye can comprise a chromophore that is also a fluorophore. 12/263, 672 filed Nov. 3, 2008 (abandoned), which is a continuation of U. 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. 5 μl of 4-vinylpyridine (distilled) was added and the sample was vortexed to solubilize the 4-vinylpyridine and then incubated for one hour at room temperature in the dark. If the sample looks clear after the mixing with the Polytron centrifugation is performed. 93; and Peptide Insulin A chain: theoretical pI: 3. 5%, or 1% of one another.

In other embodiments, the invention provides pre-labeled protein standard sets having a plurality of proteins selectively labeled on cysteine and lacking lysine, in which two or more selectively labeled proteins comprise one or more copies of an amino acid sequence depleted in lysine. 5 kDa, greater than 5 kDa, or 10 kDa or greater, migrate on electrophoresis gels, such as for example Bis-Tris gels and Tris-glycine gels as they are known in the art, within 10%, 7%, or 5% of the migration unlabeled counterparts.
The liquid fraction was discarded and 100 μl of BugBuster® HT protein extraction reagent (Novagen, Madison, Wis., USA) with 25 ug/ml lysozyme was added to the cells. The sample is vortexed for 10-15 seconds to disperse the pellet and then immediately mixed using a Polytron mixer. Reactive dyes and their preparation are well known in the art (Haugland, MOLECULAR PROBES HANDBOOK, supra, (2002)). Restriction digest screening using BamHI and EcoR I identified a positive clone and protein expression screening in BL21 DE3 STAR verified the restriction digest results.
In this case protein sequences can optionally be selected base on the abundance of cysteine and the paucity of lysine in the amino acid sequence used, which in some embodiments can reduce the number of codons to be mutated. 8 L non-baffled seed flask of approximately 1 liter of rich media with a freshly transformed (less than one week old) colony containing the expression plasmid. For example, a selectively labeled protein can comprise one or more copies of a sequence from the C-terminus of one or more ADP-ribosylation factors (Schurmann et al. The synthesis scheme is depicted in FIG. "Recombinant methods" are methods that include the manufacture of or use of recombinant nucleic acids (nucleic acids that have been recombined to generate nucleic acid molecules that are structurally different from the analogous nucleic acid molecule(s) found in nature). In some embodiments, a protein selectively labeled on cysteine lacks lysine residues. In preferred embodiments, the electrophoretic migration of each of the five or more labeled protein standards that have a molecular weight of 10 kDa or greater is within 5% of the electrophoretic migration of each of the five or more labeled protein standards calculated from the same acrylamide gels. Materials and Equipment. The modified pTrc LacZ-Flash vector was digested with BamHI-Not I and the gel purified (4377 bp) vector was ligated with the TA 50.
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. After the addition of sodium nitrite was complete the ice bath was removed and the temperature was allowed to rise to −20° C. The solution became clear as the diazonium salt formed. After two hours the pH was adjusted back to neutrality using 1 M HCl. The Blue Protein Standard, Broad Range is designed for observing protein separation during SDS-PAGE, verification of western transfer efficiency on membranes and for approximating the size of proteins.
