Product Overview
This rabbit polyclonal antibody recognizes guanine nucleotide exchange factor VAV3 in human samples and is validated for Western blot, ICC/IF and ELISA. The predicted molecular weight is 97.8 kDa, and the supplier reports an observed band at about 98 kDa.
VAV3 is a guanine nucleotide exchange factor that activates Rho-family GTPases including RhoA, RhoG and Rac1. It is phosphorylated downstream of receptor tyrosine kinases and integrins and has been linked to angiogenesis and osteoclast function. VAV3 is studied in cytoskeletal signaling and bone biology.

Immunogen
Recombinant human VAV3 fragment (Asp507–Glu702), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. Tissue expression noted by UniProt (human): Isoform 1 and isoform 3 are widely expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
