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.

2-D Quant Kit is designed for the accurate determination of protein concentration in samples prepared for electrophoresis techniques such as 2-D electrophoresis, SDS-PAGE, or IEF.

Supplier: Uptima

The BCA method is very sensitive for protein detection. Peptide bonds and the four amino acids cysteine, cystine , tryptophan and tyrosine are relevant to the determination. The formation of Cu (I) ions by proteins under alkaline conditions corresponds to the biuret method of determination. A Cu (I ) ion is then bound by two molecules of BCA to a red colour complex. This complex can be detected very sensitively.
