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.

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.
