AG73
AG73 is a polypeptide. AG73 is derived from the G domain of the Laminin α1 chain. AG73 binds heparin, Syndecan-1 and Syndecan-4. AG73 promotes the adhesion of various cells, induces the differentiation of salivary gland acinar cells, stimulates neurite outgrowth, secretion of matrix metalloproteinases and angiogenesis. AG73 retains its angiogenic activity when conjugated to chitosan membranes. AG73 can be used in the research of melanoma and ischemic injury.

Biological Activity
AG73 (200 μg/mL) completely inhibits the formation of cellular networks by mouse melanoma (B16F10) cells on Matrigel[1].
AG73 binds to immobilized biotinylated heparin with a Kd of 6.4 μM[1].
AG73 (1-100 μg/mL; 2 days) stimulates angiogenesis sprouting from 13-day-incubated chick embryo aortic rings in a dose-dependent manner[2].
AG73 (0.1-100 μg; 18 h) promotes axonal growth in 71% of PC12 cells when used at a substrate coating concentration of 100 μg[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
AG73 (1 mg/mL per mouse; s.c.; single dose) promotes vessel cell migration and angiogenesis in vivo, resulting in a mean of 55 endothelial cells per field in the subcutaneous Cultrex BME plug assay[2].
