FLASH is a fluorescein derivative, modified to contain two arsenic atoms at a set distance from each other.

Supplier: Thermo Fisher Scientific

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.

Supplier: AAT BIOQUEST

Optimised to use with Nanodrop. Amplite™ colorimetric biotin quantitation kit is designed to quantify the number of biotins attached to a protein or other macromolecule with a nanodrop spectrometer.

Supplier: Merck Millipore (Novagen)

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.

Non-Interfering Protein Assay™ Kit is an easy-to-use protein assay that overcomes interference of agents found in protein solutions including detergents, chelating agents, reducing agents, amines, sugars, urea, and others. The Universal Protein Precipitating Agent (UPPA™ Reagent) is used to precipitate and immobilize the protein in the tube while the interfering reagents are removed.

Supplier: G-Biosciences

A simple and reliable method for estimation of protein contamination in latex. Detects as low as 25 to 40 μg protein/gm latex (or 25 to 50 ppm). Protein solutions applied to the test strips form compact and symmetrical spots, their diameter being directly proportional to protein concentration. Protn-Latex™ latex protein extraction buffer extracts protein from the latex sample, which is then applied to the test strips and rapidly developed. By measuring the Ø of protein spots with the Protn-Latex™ card, the range of protein concentration in the sample can be determined.

Histones are soluble in water (10 mg/ml) or 0,5 N HCl (10 mg/ml), yielding a clear to hazy solution depending on the fraction. They are soluble in 6 M urea (4 to 10 mg/ml), but this will denature the histones.
