Antigen/Purification: ExpandCollapse

The antigen is recombinant full length human c-FOS expressed in and purified from E. Coli.

The antibody is protein G purified from culture supernatant.

Biological Significance: ExpandCollapse

c-FOS is a member of the FOS transcription factor family which forms dimers with c-JUN to produce the Activator Protein 1 (AP-1) complex which plays a key role in critical cellular processes such as cell proliferation, differentiation and apoptosis (Chiu et al., 1988).  c-FOS expression has been demonstrated to be a useful marker of neuronal activation as it is rapidly induced following various stimuli (Hoffman et al., 1993).  Additionally, c-FOS has been shown to be overexpressed in a variety of malignant tumor types (Milde-Langosch 2005).
