Grade & Purity > 98% pure
Molecular Weight 52.5 kDa
Form & Buffer Lyophilized from 10mM citric acid, pH 2.8. Reconstitute with laboratory grade water.

Usage & Assay Information

Bioactivity The ED50 was determined by the dose-dependant proliferation of the RPMI 8226 cells. The expected ED50 for this effect is 15.0-20.0 ng/ml.

Storage & Safety

Storage Store at 4 deg C until reconstitution. Following reconstitution aliquot and freeze at -20 deg C for long term storage. Avoid repeated freeze/thaw cycles.
Endotoxin Levels Endotoxin level is less than 0.1 ng per ug (1 EU/ug).

General Information

Biological Significance Visfatin is a 55 kDa protein produced and secreted primarily by white adipose tissue. Recently, Visfatin was isolated from visceral fat deposits and shown to possess insulin-mimetic activity. Like insulin, Visfatin exerts hypoglycemic effects by interacting with the insulin receptor. The binding affinity of Visfatin for the insulin receptor is similar to that of insulin, but it does not compete with insulin, suggesting that the two proteins interact with different receptor sites. The circulating levels of Visfatin are much lower than those of insulin and are not affected by feeding, implying that the hypoglycemic effect of Visfatin may not be of physiological importance.
