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: 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.

Osteocrin is a recently identified secreted protein expression of which was only detected in bone, peaking just after birth and decreasing markedly with age. A 1280-bp mRNA encodes osteocrin producing a mature protein of 103 amino acids with a molecular mass of 11,4 kD. In primary osteoblastic cell cultures osteocrin expression coincided with matrix formation then decreased in very mature cultures.
