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 1C7 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Apaf-1. It targets an epitope within 25 amino acids from the C-terminal region.

KLH-conjugated linear peptide corresponding to 25 amino acids from the C-terminal region of human Apoptotic protease-activating factor 1 (Apaf-1).

Apoptotic protease-activating factor 1 (UniProt: O14727; also known as Apaf-1) is encoded by the Apaf1 (also known as KIAA0413) gene (Gene ID: 317) in human. Apaf-1 is a ubiquitously distributed protein that plays a role in intrinsic apoptotic cell death. Apaf-1 contains a caspase recruitment domain (aa 1-90), an ATPase domain (NB-ARC)(aa 104-415), few short helical domains, and several copies of the WD40 repeat domains. Its highest expression is observed in the adult spleen and peripheral blood leukocytes, and in fetal brain, kidney and lung. Isoform 1 is expressed in heart, kidney, and liver. Under basal conditions it is a monomeric protein, but oligomerizes under apoptotic conditions.  The monomeric form is auto-inhibited in a closed conformation through a bound ADP at the nucleotide binding site. Under apoptosis signals ADP is exchanged for ATP and its binding to cytochrome c triggers a conformation change where WD repeat region swings out, which allows the NB-ARC domain to rotate and expose the contact areas for oligomerization. Oligomeric form is a heptameric ring that binds to cytochrome c, pro-caspase-9, and ATP  to form apoptosome. Oligomeric Apaf-1 mediates the cytochrome c-dependent autocatalytic activation of pro-caspase-9 to mature caspase-9, which then activates effector caspases 3, 6, and 7. Since Apaf-1 does not have any caspase activity, pro-caspase-9 is believed to be activated through autocatalysis in the apoptosome. Thus, cytochrome c release from the mitochondria is considered as a key signal that initiates the irreversible events in cell death. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.

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.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
