Anti-RNPEP Antibody

Polyclonal antibody raised in rabbit against RNPEP (Arginyl Aminopeptidase, AP-B), a zinc-dependent metalloaminopeptidase that selectively cleaves N-terminal arginine and leucine residues from peptide substrates. Distributed by Antibodies.com, this unconjugated IgG antibody is supplied as a 200 µl liquid aliquot and is validated for Western Blot application across human, mouse, and rat samples.

RNPEP is expressed in tissues including kidney, liver, brain, and immune cells, where it contributes to peptide hormone processing, antigen presentation in the MHC class I pathway, and hematopoietic cell differentiation. Researchers apply this reagent to investigate RNPEP expression levels, subcellular localization, and involvement in disorders such as hematological malignancies, infection responses, and cardiovascular signaling cascades. The antibody is appropriate for immunoblotting of cell lysates and tissue homogenates, supporting studies of aminopeptidase biology and protease pathway regulation. Samples should be handled using standard immunoblotting protocols, with aliquoting recommended to limit freeze-thaw cycles.
