CCGTTACGGAAAAGCAGAAG. As shown by the diagram of FIG. The nucleic acid sequences from a source other than the source of the nucleic acid molecule directly or indirectly isolated from an organism can be nucleic acid sequences from or within the genome of a different organism. 5 to 260 kDa and is supplied in a ready-to-use format for direct loading onto gels; no need to heat, reduce, or add sample buffer prior to use. Gel electrophoresis in particular is a common tool for the development of new drugs and medical diagnostics that is typically performed with molecular weight markers. A positive clone was identified by colony PCR using the 50. The pTrc 160+LacZ clone B1 in BL 21 DE3 was expressed in 1. Novex™ Sharp Pre-stained Protein Standard. Lane 2: Novex Sharp 10µl. However, we are committed to improving your shopping experience. 6A shows a map of the pTrc BH 50 kDa "No Lysine" construct.

A selectively labeled protein can be a naturally-occurring protein isolated from cells, tissue, organisms, biological samples, or media, or can be made using recombinant methods. 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). A protein standard selectively labeled on cysteine can optionally be made by recombinant methods from a nucleic acid construct that encodes at least a portion of a sequence of a naturally-occurring protein, in which one or more lysine, histidine, or tryptophan codons has been removed. Additional target amino acid codons can be added to a nucleic acid sequence that encodes a protein standard of the invention. Novex sharp prestained protein standard mix. In some preferred methods of labeling cysteine residues, the reducing agent is beta-mercaptoethanol, dithiothreitol, TCEP, or TBP. A dye can be, for example, a chromophore or a fluorophore.

5 residues of the target amino acid per 10 kDa. 15) alongside other commercially available 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). For example, "about 50° C. Novex sharp prestained protein standard edition. " (or "approximately 50° C. ") encompasses a range of temperatures from 45° C. to 55° C., inclusive. Key product features: - Broad range: 10-245 kDa. 5-8 it was adjusted with NaOH. Non-synonymous amino acid alterations in PfEBA-175 modulate the merozoite ligand's ability to interact with host's Glycophorin A receptor.

Primer design allowed for each 50 kd TA clone to have unique sequence ends that facilitated vector construction as shown in Table 2. At low pH the dye is a purple color and the fractions collected were in some cases checked by HPLC to assess purity. TAATACGACTCACTATAGGG. Prestained protein ladder novex. 5 ml pre-stained ELITE Protein Ladder (10 x 0. The migration of the labeled proteins was measured on Alpha Imager 3000 imaging system. The method used for purification was the following: insulin was solubilized at 5 mg/ml in 8M urea, 50 mM Tris pH=8. Please use the form below to provide feedback related to the content on this product. A protein that is "deficient in an amino acid" means that the protein has no residues of the amino acid.

5 μl of 4×LDS and 2 μl NuPAGE reducing reagent were added to 15 μl of the whole lysate and to 15 μl of insoluble fraction. 13 depicts the reaction scheme for generating the vinyl sulfone form of Orange 16. The standards can have two or more, three or more, four or more, five or more, or six or more protein standards that differ by an increment that is a multiple of 10 kDa (plus or minus 1 kDa). As nonlimiting examples, a fluorophore used to label a protein standard can be an Alexa fluor dye, a BODIPY dye, fluoroscein or a derivative thereof, eosin or a derivative thereof, tetramethylrhodamine, rhodamine or a derivative thereof, Texas red or a derivative thereof, pyridyloxazole or a derivative thereof, NBD chloride, NBD fluoride, ABD-F, lucifer yellow or a derivative thereof, 8-anilino-1-naphthalenesulfonic acid (8-ANS) or a derivative thereof, or Oregon green or a derivative thereof. Comprehensive - a wide range of molecular weight bands consisting of 12 proteins in the range of 3. The pH was maintained at 10. 5%, or 1% of one another are selectively labeled on a first amino acid. The calculated molecular weights of the proteins can be performed by curve-fitting of molecular weight to migration distances or point-to-point calculation. More than one amino acid can be targeted for selectively labeling a protein. 6, 704, 484, herein incorporated by reference in its entirety. ) Protein standards can be produced in cell culture and purified for selective labeling on one or more target nucleic acids.
In another example, glutamate can be a target amino acid, and aspartate can be a non-target amino acid. 7 kd) and the remaining five identical repeats were set at 258 bp (each providing a translation product of 9. In some illustrative embodiments of these aspects of the invention, a selectively labeled protein standard is a protein that is labeled on a target amino acid and comprises one or more copies of an amino acid sequence that is homologous to a sequence of a naturally-occurring protein, in which the sequence having homology to an amino acid sequence of a naturally-occurring protein sequence lacks a non-target amino acid. 69 g of sodium nitrite was mixed in 20 mL of water until it was completely dissolved. Proteins of a pre-labeled protein standard set that are labeled with a dye on a target amino acid and have ratios of the number of residues of the target amino acid to molecular weight that are within 5% of one another can be labeled with the same dye, or with different dyes. PCR colony screening identified 11/80 clones containing the LacZ insert and expression screening identified 5/11 clones having the LacZ insert in the correct orientation.
2 mM to about 5 mM, or from about 0. The protein contained 73 cysteines and 19 lysine amino acids. 1 D3 which had been also digested with XhoI and PmeI. For example, 4-12% NuPAGE® Bis-Tris acrylamide 8 cm×8 cm gels using MOPS or MES buffer, or 4-20% Tris-glycine 8 cm×8 cm acrylamide gels available from Invitrogen (Carlsbad, Calif. ) can be used to determine migration properties of labeled and unlabeled protein standards using electrophoresis conditions provided in the manufacturer's manual for separating proteins. Labeled proteins of a pre-labeled protein standard set on the invention that are not selectively labeled can be recombinant proteins or proteins isolated from cells, tissues, organisms, biological samples, or media. Application||Abreviews||Notes|. Ab116028 has been referenced in 16 publications. In some preferred embodiments, a pre-labeled protein standard set comprises at least five labeled proteins, in which three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, or more of the proteins lack lysine and are labeled on cysteine, and have an average of between three and five residues of cysteine, such as between 3. An excess of labeling compound over target amino acid is typically used in the labeling reaction.
