Growth Hormone (GH) is a 23 kDa circulating pituitary hormone, Rat GH shares approximately 97% homology with mouse GH and 65% homology with human GH in its protein sequence.

GIP, also known as gastric inhibitory polypeptide, or glucose-dependent insulinotropic polypeptide, is a 42 amino acid peptide hormone synthesized in and secreted from K cells in the intestinal epithelium.

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…

Sterivac vacuum-driven filter units are ideal for bottle-top filtering directly into receiver flasks at flow rates as fast as 1.5 L/min. The unique "start & stop" filtration action makes setting up, filtering and transferring the unit to another receiver fast and easy. Push a button to stop filtering, move the device to an empty bottle and restart
