AIF in HeLa Human Cell Line.
AIF was detected in formaldehyde fixed HeLa human cervical epithelial carcinoma cell line using Rabbit Anti-Human/Mouse/Rat AIF Alexa Fluor® 488‑conjugated Antigen Affinity-purified Polyclonal Antibody (green; Catalog # IC1457G) at 1:10 dilution overnight at 4 ° C and counterstained with DAPI (blue). Specific staining was localized to mitochondria. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Apoptosis-inducing factor (AIF, also known as programmed cell death protein 8) is a 58 kDa member of the FAD-dependent oxidoreductase family of molecules. It is ubiquitously expressed and found in the mitochondrial intermembrane space. AIF likely acts as a mitochondrial antioxidant providing protection via NADH oxidase activity. Upon release from the mitochondria, AIF passes into the nucleus where it initiates apoptosis. Human AIF precursor is 67 kDa in size and 613 amino acids (aa) in length and contains a cleavable N-terminal 102 aa mitochondrial localization sequence, followed by a spacer region (aa 103‑129) and an oxidoreductase domain (aa 130‑613) that possesses an NLS (aa 446‑451). Over aa 121‑613, human AIF shares 95% aa identity with mouse AIF.
