Recombinant Rat Resistin

Description :
FAQ COA 已发表文献 Resistin (resistance-to-insulin), also known as adipocyte-specific secretory factor (ADSF) and found in inflammatory zone 3 (FIZZ3), is a 10 kDa member of a small family of secreted cysteine-rich peptide hormones. Human Resistin precursor is 108 amino acids (aa) in length. It contains an 18aa signal sequence plus a 90aa mature region. The mature region shows an N-terminal alpha -helical tail (aa 23 44) and a C-terminal beta sheet globular head (aa47 108). Mature human Resistin shares 56%and 54%aa identity with mouse and rat Resistin, respectively. Rat Resistin possesses an alternate start site at Met48; this Met is not found in the mouse molecule, however. Although the function of Resistin is unclear, it would seem to block insulin-stimulated uptake of glucose by adipocytes and promote glucose release by hepatocytes. As such, it has been proposed to participate in dietinduced insulin-sensitivity.

Purity >97% by SDS-PAGE and HPLC analyses. Biological Activity Test in process. Endotoxin Formulation Lyophilized from a 0.2 m filtered concentrated solution in PBS, pH7.4, with 0.02% Tween-20. Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at -20. Further dilutions should be made in appropriate buffered solutions.
