Thermo Scientific™ Pierce™ Quantitative Colorimetric Peptide Assay is an easy-to-use colorimetric microplate assay designed specifically to improve the sensitivity and reproducibility of quantitation of peptide mixtures.

Supplier: Boster Bio

The Micro BCA Protein Assay Kit is a ready to use, detergent-compatible, Western blot related, total protein analysis reagent used for the quick determination of total protein concentration of dilute protein solutions by measuring absorbance at 562 nm and comparing to a protein standard absorbance vs. concentration curve.

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.

Supplier: MP Biomedicals

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.

Supplier: Cytiva

Kit développé pour la détermination de protéines concentrées à partir de gels d'électrophorèse 2-D, SDS-PAGE ou IEF.

Supplier: Abnova

Biotin Labelling Kit is used for simple and rapid preparation of biotin-labeled antibodies and proteins.

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.
