Visfatin is an adipokine produced by visceral adipose tissue. Other adipokines include leptin, adiponectin, resistin, chemerin, omentin and vaspin. Visfatin has been shown to act as a pro-inflammatory factor for PBMCs and may mimic the effects of insulin on adipocytes, monocytes and hepatocytes.

Source:
Recombinant protein corresponding to 466aa from human Visfatin expressed in E.coli.

Molecular Weight:
~52.6kD

Endotoxin:
1EU/ug (LAL)

Biological Activity:
The activity is determined by its ability to induce IL-6, IL-1 beta and TNF alpha production from human PBMCs at 100ng/ml.
