Insulin, a 5.8 kDa hormone, is secreted by the islet beta cells in the pancreas.

The OxyELISA™ Oxidized Protein Quantitation Kit provides a sensitive methodology for detection and quantitation of proteins modified by oxygen free radicals and other reactive species. Oxygen-derived free radicals have been implicated in numerous physiological functions such as apoptosis, cancer, aging, neurodegenerative diseases, chronic inflammatory diseases, pulmonary diseases, and cardiovascular diseases (for reviews, see…

TMB, (3,3',5,5'-tetramethybenzidine) has been shown to be a safe-sensitive substrate for the assay of HRP. Initially, in the presence of HRP and hydrogen peroxide, a one-electron oxidation product is formed. This compound, a cation free radical, is blue in color with an adsorption maximum of 653 nm. Further reaction with HRP/H2O2 or acidification of the radical with acid yields the diimine terminal oxidation product adsorbing…

The PrismA ELISA kit is an enzyme-linked immunosorbent assay designed to measure residual ligand leakage when using MabSelect PrismA ™ chromatography resin and Fibro ™ PrismA chromatography adsorbers. The kit is used during the development and manufacture of monoclonal antibody (mAb) biopharmaceuticals.

The Dual-Action manifold optimizes washing for a variety of cell types, in addition to biomagnetic protocols in plate configurations from 96- to 1536-well. Non-contact plate dispensing capabilities offer flexibility, including up to four syringe pumps and two peristaltic pump dispensers enab…

Commercially available antibodies often contain substances (e.g. BSA, glycine, tris, azide) that interfere in labeling reactions with enzymes or fluorophores. The AbSelect™ Purification Kit quickly removes these contaminants of antibody labelling. It can also be used to purify antibodies from crude samples such as ascites fluid or immune serum. The antibody to be purified or cleaned up ideally is in a volume of 100ul to 0.5m…
