ERAP1 antibody is human and mouse reactive. At least two isoforms of ERAP1 are known to exist, this antibody will detect both isoforms. ERAP1 antibody is predicted to not cross-react with ERAP2.
Purification
ERAP1 Antibody is affinity chromatography purified via peptide column.
Immunogen
ERAP1 antibody was raised against a 19 amino acid peptide near the carboxy terminus of human ERAP.
The immunogen is located within amino acids 730 - 780 of ERAP1 .
The endoplasmic reticulum (ER) aminopeptidase 1 (ERAP1), a member of the peptidase M1 family, plays a central role in peptide trimming, a step required for the generation of most HLA class I-binding peptides (1,2). It is also designated as adipocyte-derived leucine aminopeptidase (A-LAP), puromycin-insensitive leucine-specific aminopeptidase (PILS-AP) and aminopeptidase regulator of TNFR1 shedding (ARTS-1) (3). ERAP1 is localized to the lumen of the ER and induced by interferon. It may be involved in the regulation of blood pressure through the inactivation of angiotensin II and/or the generation of bradykinin in the kidney (3,4).
