General description

We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Green Chemistry.This antibody is Preservative-free, produced without the harm or sacrifice of animals and exceptionally stable to allow for ambient shipping and storage if needed and thus aligns with "Waste Prevention", "Designing Safer Chemicals" and "Design for Energy Efficiency". Click here for more information.
ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies.Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.


Clone 1I15 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects Ferroptosis suppressor protein 1 (AIFM2). It targets an epitope within 21 amino acids from the C-terminal region.


KLH-conjugated linear peptide corresponding to 21 amino acids from the C-terminal region of human Ferroptosis suppressor protein 1 (AIFM2).


Quality Control Testing

Flow Cytometry Analysis: 1 μg from a representative lot detected AIFM2 in one million HepG2 cells.

Immunocytochemistry Analysis: A 1:1,000 dilution from a representative lot detected AIFM2 in HeLa, A431, HUVEC, and NIH3T3 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-AIFM2, clone 1I15 ZooMAb®, Cat. No. ZRB1527, is a recombinant Rabbit monoclonal antibody that detects AIFM2 and is tested for use in Affinity Binding Assay, Flow Cytometry, Immunocytochemistry, and Western Blotting.

Target description

Ferroptosis suppressor protein 1 (UniProt: Q9BRQ8; also known as FSP1, Apoptosis-inducing factor homologous mitochondrion-associated inducer of death, AMID, p53-responsive gene 3 protein, AIFM2) is encoded by the AIFM2 (also known as AMID, PRG3) gene (Gene ID: 84883) in human. AIFM2 is a lipid-anchor membrane protein of the FAD-dependent oxidoreductase family that is also detected in the nucleus and mitochondrial membrane. It is highly expressed in heart and moderately in liver and skeletal muscles. Low expression levels are observed in placenta, lung, kidney, and pancreas. It is reported to be down-regulated in a number of human tumors. It serves as a NAD(P)H-dependent oxidoreductase and is involved in cellular oxidative stress response. At the plasma membrane, it catalyzes reduction of coenzyme Q/ubiquinone-10 to ubiquinol-10, a lipophilic radical-trapping antioxidant that prevents lipid oxidative damage and consequently ferroptosis. It is shown to cooperates with GPX4 to suppress phospholipid peroxidation and ferroptosis and its anti-ferroptotic function is reported to be independent of cellular glutathione levels. It also plays a role in mitochondrial stress signaling. Upon induction of oxidative stress, it associates with the lipid peroxidation end product 4-hydroxy-2-nonenal (HNE) forming a lipid adduct. This HNE adduct inactivates the NADH oxidoreductase activity of AIFM2 and facilitates its translocation from mitochondria into the nucleus triggering DNA damage and cell death. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb® formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
