Human Adiponectin RIA Kit

Adiponectin is a new member of the ever increasing family of adipocytokines. This protein is also known as ACRP-30 (adipocyte compliment related protein-30), Adipo-Q, APM-1 (adipose tissue most abundant gene transcript-1). It is a predominant secretory protein from adipose tissue and circulates in micro-gram per ml quantities.  Adiponectin has a structural homology with the type VIII collagen and hibernation specific protein, C1q.

In contrast to the majority of secreted proteins from adipose tissue, which are elevated in obesity, adiponectin appears to be either decreased or unaltered with degree of adiposity. More intriguingly, adiponectin seems to ameliorate the obesity related risk factors unlike other adipose tissue secretory proteins which contribute toward the health risks associated with obesity. Adiponectin also has an insulin sensitizing effect making it an excellent candidate in drug development for obesity and diabetes. Circulating adiponectin levels appear to be an excellent biochemical to monitor insulin sensitivity in a spectrum of insulin resistant patients such as type II diabetes, obese subjects, syndrome "X", etc. during therapeutic intervention. This kit is for research purposes only.
