Western blot analysis of extracts from C6 (lane 2(20μg) , NIH/3T3 (lane 3(20μg) , C2C12 (lane 4(20μg),using AIF Antibody (HY-P80006). Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature.

Immunocytochemistry analysis of SK-OV-3 cells labeling AIF with AIF Antibody (HY-P80006) at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with AIF Antibody (HY-P80006) at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L(HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Immunohistochemical analysis of paraffin-embedded Rat liver tissue using AIF Antibody (YA636). The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HY-P80006, 1/1000) in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Flow cytometric analysis of 1X10^6 Hela cells labeling AIF Antibody(HY-P80006, red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/1000 dilution for an hour at 4℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L (HY-P8002) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Rabbit IgG Isotype Control (HY-P80879, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
Background

Function
AIF functions both as NADH oxidoreductase and as regulator of apoptosis. In response to apoptotic stimuli, it is released from the mitochondrion intermembrane space into the cytosol and to the nucleus, where it functions as a proapoptotic factor in a caspase-independent pathway. Release into the cytoplasm is mediated upon binding to poly-ADP-ribose chains. The soluble form (AIFsol) found in the nucleus induces 'parthanatos' i.e. caspase-independent fragmentation of chromosomal DNA. Binds to DNA in a sequence-independent manner. Interacts with EIF3G, and thereby inhibits the EIF3 machinery and protein synthesis, and activates caspase-7 to amplify apoptosis. Plays a critical role in caspase-independent, pyknotic cell death in hydrogen peroxide-exposed cells. In contrast, participates in normal mitochondrial metabolism. Plays an important role in the regulation of respiratory chain biogenesis by interacting with CHCHD4 and controlling CHCHD4 mitochondrial import; Has NADH oxidoreductase activity. Does not induce nuclear apoptosis; Pro-apoptotic isoform[1][2][3][4][5][6][7].

Expression
Tissue_specificity:Expression was observed in all tested tissues (PubMed: 16644725) . Detected in muscle and skin fibroblasts (protein level) (PubMed: 23217327) . Expressed in osteoblasts (protein level) (PubMed: 28842795) ; brain-specific; expressed in all tested tissues except brain tissue; isoform 5 is frequently downregulated in human cancers.
Induction:Strongly down-regulated in many tumor cells, up-regulated by gamma-irradiation -
Subunit
Monomer (oxidized form). Homodimer (reduced form). Upon reduction with NADH, undergoes dimerization and forms tight, long-lived FADH2-NAD charge transfer complexes (CTC) resistant to oxidation (PubMed:20111043, PubMed:23217327, PubMed:24914854, PubMed:27818101). Also dimerizes with isoform 3 preventing its release from mitochondria (PubMed:20111043). Interacts with XIAP/BIRC4 (PubMed:17967870). Interacts (via N-terminus) with EIF3G (via C-terminus) (PubMed:17094969). Interacts with PRELID1 (PubMed:21364629). Interacts with CHCHD4; the interaction increases in presence of NADH (PubMed:26004228). Interacts with processed form of PARP1 (Poly [ADP-ribose] polymerase 1, processed C-terminus); interaction is mediated with poly-ADP-ribose chains attached to PARP1, promoting translocation into the nucleus (PubMed:33168626)
