Scientific Background
Apoptosis inducing factor is involved in initiating a caspase-independent pathway of apoptosis (positive intrinsic regulator of apoptosis) by causing DNA fragmentation and chromatin condensation. It also acts as an NADH oxidase. Another AIF function is to regulate the permeability of the mitochondrial membrane upon apoptosis. Normally it is found behind the outer membrane of the mitochondria and is therefore secluded from the nucleus. However, when the mitochondria is damaged, it moves to the cytosol and to the nucleus. Inactivation of AIF leads to resistance of embryonic stem cells to death f.
Assay Principle
This assay employs a two-site sandwich ELISA to quantitate AIFM1 in samples. An antibody specific for AIFM1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyAIFM1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for AIFM1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of AIFM1 bound in the initial step. The color development is stopped and the intensity of the color is measured.

Safety & Regulatory
Handle reagents in accordance with institutional biosafety guidelines. Refer to the Safety Data Sheet (SDS) for complete hazard and handling information. Contains components that may require special disposal procedures per local regulations.
This kit is validated for use with serum, plasma, cell culture supernatant, tissue homogenate. For unlisted matrices (e.g., tissue lysate, urine), perform a spike-and-recovery experiment to confirm assay performance before generating reportable data. Sample dilution in the kit's provided diluent is recommended to minimize matrix interference.
The minimum detectable concentration (sensitivity) of this kit is 0.061 ng/mL. Values below this threshold should be reported as below the limit of detection (<LOD) and should not be extrapolated from the standard curve.
The total assay time from sample addition to absorbance reading is approximately 3.5–5 hours, including all incubation, wash, and substrate steps. Hands-on time is typically 1–2 hours; most steps involve passive plate incubation. Plan the assay as a single uninterrupted session for best results.
Standard components of this Sandwich ELISA Kit typically include: pre-coated microplate (96-well strip format), lyophilized or liquid recombinant AIFM1 standard, detection antibody, streptavidin-HRP conjugate, TMB substrate, stop solution, wash buffer concentrate, and sample/standard diluent. Refer to the kit insert or datasheet for the exact component list and storage requirements.
This kit uses colorimetric (TMB/HRP) detection and requires a standard microplate absorbance reader capable of measuring at 450 nm. A reference wavelength of 570 nm or 630 nm is recommended to reduce background. No specialized fluorescence or luminescence reader is needed. Ensure the instrument is calibrated and the plate is clean and free of condensation before reading.
