Product Overview
This rabbit polyclonal antibody detects serine/threonine-protein kinase A-Raf (gene ARAF) in human, mouse and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 67.6 kDa, and the supplier reports an observed band at about 68 kDa.
A-Raf (ARAF) is a serine/threonine kinase of the RAF family, alongside BRAF and CRAF. Activated downstream of RAS, RAF kinases phosphorylate MEK to drive the ERK/MAPK pathway that relays growth signals to the nucleus, and ARAF is studied in cell proliferation and RAS-driven signaling.
