Accurately quantifying total protein concentration is a key to most experiments and is often necessary for isolation, separation, and analysis of proteins by biochemical methods. When it is necessary to determine the total protein concentration in a sample, one of the first factors to consider is the selection of a protein assay method. These choices are typically based upon the compatibility of the method with the samples to be assayed. Each method has its own advantages and disadvantages.

Solid phase biotinylation kits, EZ-Link™, Pierce™

Fornecedor: Thermo Fisher Scientific
Descrição: This antibody labeling system uses nickel chelated agarose to temporarily immobilise antibody molecules via their histidine-rich Fc regions. Once held in place on the gel, the antibody can be biotinylated at either sulfhydryl groups (after mild reduction or disulfide bonds) or primary amines. Excess labeling reagent and by-products are then washed away before recovering the labeled and purified antibody from the gel using a mild imidazole solution. No gel filtration or dialysis are needed.

Image Unavailable-71840-3

Antibody labelling kits, HisTag® Antibody HRP Conjugate kit

Código de Artigo: (71840-3)
Fornecedor: Merck Millipore (Novagen)
Descrição: The HisTag® Antibody HRP Conjugate kit contains a horseradish peroxidase-conjugated HisTag® Monoclonal Antibody that is useful as a single detection reagent, thus eliminating cross-reactivity associated with secondary antibody reagents. It recognises five consecutive histidine residues regardless of the surrounding amino acid context. The purified antibody conjugate produces a strong signal at a 1:1000 to 1:2000 dilution on Western blots and dot blots. The HisTag® Antibody HRP Conjugate also detects the recombinant marker bands in the Novagen Perfect Protein™ Western Markers for convenient visualisation of accurate internal standards on Western blots.

Pierce™ BCA™ Protein assay kits and reagents

Fornecedor: Thermo Fisher Scientific
Descrição: Pierce BCA™ (bicinchoninic acid) reagents provide accurate determination of protein concentration with most sample types encountered in protein research. The Pierce BCA™ Protein Assay can be used to assess yields in whole cell lysates and affinity-column fractions, as well as to monitor protein contamination in industrial applications. Compared to most dye-binding methods, the BCA™ Assay is affected much less by protein compositional differences, providing greater protein-to-protein uniformity.
