Anti FGF1, Monoclonal Antibody (mAb1)

FGF1 (fibroblast growth factor 1, aFGF, or acidic fibroblast growth factor) is a non-glycosylated heparin-binding growth factor expressed in the brain, kidneys, retina, smooth muscle cells, bone matrix, osteoblasts, astrocytes, and endothelial cells. It is involved in growth, differentiation, and survival of a variety of tissues and cells.

A recent report has indicated that FGF1 plays an important role in metabolic homeostasis by acting as a transducer of PPARγ signaling involved in adipose remodelling 11).
