The column is washed until the signal UV 280 nm signal goes to the baseline with Column Conditioning Solution. Preferred conservative amino acid substitution groups are: valine-leucine-isoleucine; phenylalanine-tyrosine; lysine-arginine; alanine-valine; glutamic acid-aspartic acid; and asparagine-glutamine. The pre-labeled protein standard set can include two or more, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, or more proteins that are selectively labeled on cysteine and are depleted in lysine, in which the selectively labeled proteins comprise one or more copies of an amino acid sequence depleted in lysine. The sequence-verified Thio repeat ORF insert (BH6mer ORF) from BlueHeron® Biotechnology (FIG. In some embodiments, the proteins standards have amino acid tag sequences, such as amino acid tags that can be used to purify the proteins. Novex sharp prestained protein standard gold. The solution was heated for 5 minutes at 70° C. with occasional vortexing. The sample was vortexed to resuspend the cells and incubated for 10 minutes at room temperature.

It is generally preferred that the reagents be kept as concentrated as practical so as to obtain adequate rates of conjugation. Concentration information loading... Research areas. Field of the Invention. The column is attached to a stand and the liquid is drained from the column. 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). Two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, or more copies of the nucleic acid sequence encoding a truncated thioredoxin can be assembled together to make a recombinant protein having multiple copies of a truncated thioredoxin sequence. The column is equilibrated with 50 mM Tris, 1% SDS pH=8. A molecule or chemical group that is conjugated to another molecule or chemical group is covalently bound. In some illustrative embodiments, a selectively labeled protein standard selectively labeled on lysine is depleted in or lacks residues of at least one of cysteine, histidine, or tryptophan. Allows approximate molecular weight determination when performing SDS-PAGE analysis. 2 clone B3 was digested with XhoI and Not I (site from pCR2. Novex sharp prestained protein standard mix. Rich media per liter: 12 grams of tryptone, 24 grams of yeast extract dissolved in distilled water to a final volume of 1 liter is autoclaved, and after cooling to approximately 30 degrees C., 10 mls of 10 mg/ml ampicillin, 50 mls of 20×NPS, 10 mls of 5052 solution, and 1 ml of 1 molar Magnesium Sulfate are added. 2A is a diagram of a nucleic acid construct (BH6mer ORF) having six copies of a truncated thioredoxin sequence lacking lysine separated by unique restriction sites.

Group 1 metabotropic glutamate receptors trigger glutamate-induced intracellular Ca2+ signals and nitric oxide release in human brain microvascular endothelial cells. Novex™ Sharp Pre-stained Protein Standard. For purification of lysozyme labeled with Uniblue-A, Bio-Gel P-6 column equilibrated with 8M urea was used. 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. 14 ml 60% TCA is added to 30 ml protein solution obtained from the Ni-NTA purification add and mixed well. Reducing side reactions can be by either or both of: modifying one or more chemical groups that are capable of reacting with the reactive group of the dye such that they are no longer capable of reacting with the labeling compound under the reaction conditions used to label the protein, and selecting a protein for labeling that is depleted in amino acids that have chemical groups capable of reacting with the dye used for labeling the protein.

Novex Sharp Prestained Protein Standard Range

891 kDa protein having a truncated thioredoxin linked to two copies of a 5 kDa fragment of the Dead-box protein, (Invitrogen Corp., Carlsbad, Calif. 6, 703, 484) was labeled for use as the 20 kDa standard of the pre-labeled marker set. Ab116028 has been referenced in 16 publications. The set of pre-labeled protein standards of the kit can be provided as lyophilized solids, or in solution in liquid or frozen form. The method includes: adding a labeling compound to a protein that lacks cysteine residues under conditions that allow conjugation of the dye with lysine. 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. 10) was cloned into the AvrII site. In some embodiments, pre-labeled protein standard set of the invention can span any molecular weight range, but in preferred embodiments spans a molecular weight range of from 10 kDa or less to 100 kDa or greater, or from 10 kDa or less to 150 kDa or greater, or from 5 kDa or less to 150 kDa or greater, or from 10 kDa or less to 200 kDa or greater, or from 5 kDa or less to 200 kDa or greater, or from 10 kDa or less to 250 kDa or greater, or from 5 kDa or less to 250 kDa or greater. 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 starting material, Reactive Orange 16 (also called Remazol Brilliant Orange 3R), was obtained from Sigma-Aldrich Chemical Company. De-ionize for 2 or more hours with 10 g/liter Amberlite mixed bed resin. In some preferred embodiments, the two or more labeled proteins are selectively labeled on a first amino acid and comprise one or more copies of an amino acid sequence of a naturally-occurring protein or having at least 70% or at least 80% identical to at least 20, at least 30, at least 40, or at least 50 contiguous amino acids of a naturally-occurring protein. In some preferred embodiments, the proteins having ratios of first amino acid to molecular weight within 10%, 5%, 2. 5 kDa, or between about 0.

Multiple standards are preferably compared on the same gel, in which 5 μl of each marker protein sample is loaded between lanes of the BSA standard. The Novex™ Sharp Pre-Stained standard loading buffer consists of 65 mM Tris pH 6. The column is plugged with a cap and 4 ml 8M urea, 20 mM phosphate, 500 mM NaCl pH=7. DETAILED DESCRIPTION OF THE INVENTION. This generally occurs 14-17 hours after inoculation. The sodium nitrite solution was added dropwise to the mixture and the solid in the flask began to dissolve with a yellowish/green color developing in the solution. The PCR inserts were TA cloned into pCR2.

Reactive dyes and their preparation are well known in the art (Haugland, MOLECULAR PROBES HANDBOOK, supra, (2002)). Reactive chemical groups such as, for example, can be added to a dye using techniques that are known in the art of organic chemistry. In the context of the present invention, "selectively labeled" means labeled predominantly on particular sites of a biomolecule. "Target amino acid" refers to an amino acid species, for example lysine, by which is meant all lysine residues of a protein, and is not used to refer to a single particular lysine residue of a protein. D) incubating the protein with the reducing agent for a sufficient amount of time for cysteine-cysteine bonds to be reduced. The dye was purified using a reverse phase column. The second amino acid is preferably a nontarget amino acid that can react with the labeling compound. Labeling of Standard Proteins with Dyes. To our knowledge, customised protocols are not required for this product. 5%, or 1% of one another. For example, cysteine can be a target amino acid of a pre-labeled protein standard where the labeling compound attached to the pre-labeled standard is a labeling compound that, prior to conjugation with the protein, comprised a reactive chemical group that reacts with the sulfhydryl group of cysteine, such as but not limited to: vinyl sulfone, iodoacetamide, maleimide, disulfides, mercurial compounds, haloacetyl compounds, and iodoacetic acid. Pre-Labeled Protein Standard Sets with Proteins Selectively Labeled on a First Amino Acid. The first peak is collected as the protein peak. The standards can span a molecular weight range of from less than 10 kDa to greater than 100 kDa, or from less than 5 kDa to greater than 250 kDa.
