ARC Antibody: Apoptosis is regulated by death domain (DD) and/or caspase recruitment domain (CARD) containing molecules and a caspase family of proteases. CARD containing cell death regulators include RAIDD, RICK BCL10, Apaf-1, caspase-9, and caspase-2. A novel CARD domain containing protein was recently identified and designated ARC for apoptosis repressor with CARD. ARC interacts with caspase-2 and -8 and inhibits enzymatic activity of caspase-8. ARC suppresses apoptosis induced by cell death adapters FADD and TRADD and by cell death receptors Fas, TNFR-1, and DR3. The messenger RNA of ARC is primarily expressed in skeletal muscle and cardiac tissue.

IgG
Clonality/Clone
This is a polyclonal ARC Antibody.
Conjugate
None
Purification
ARC Antibody is affinity chromatography purified via peptide column.
Host
ARC antibody was raised in rabbit.
Please use anti-rabbit secondary antibodies.
Immunogen
ARC antibody was raised against a peptide corresponding to amino acids 2 to 18 of human origin. These sequences are identical to those of human nuclear protein Nop30 (2) and differ from those of the rat homolog of ARC by one amino acid (3).
Application
ARC antibody can be used for detection of ARC by Western blot at 1:500 dilution. An approximately 25 kDa band can be detected.
ARC Antibody is supplied in PBS containing 0.02% sodium azide.
Blocking Peptide
Cat. No. ZP-2185 – ARC Peptide
Storage
ARC antibody can be stored at 4˚C for three months and -20˚C, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
