Human Cathepsin A/Lysosomal Carboxypeptidase A Antibody Summary

Species Reactivity

Human

Specificity

Detects both pro and active forms of human and mouse Cathepsin A/Lysosomal Carboxypeptidase A in direct ELISAs and Western blots. In Western blots, it recognizes all forms of recombinant human Cathepsin A: single chain (55 kDa), heavy chain (32 kDa), and light chain (20 kDa). Also in Western blots, less than 1% cross-reactivity with recombinant human (rh) Cathepsin B, rhCathepsin C, rhCathepsin D, rhCathepsin L, rhCathepsin L2/V, rhCathepsin O, rhCathepsin S and rhCathepsin X/Z/P is observed.

Cathepsin A/Lysosomal Carboxypeptidase A in Human Prostate. Cathepsin A/Lysosomal Carboxypeptidase A was detected in immersion fixed paraffin-embedded sections of human prostate using Goat Anti-Human Cathepsin A/Lysosomal Carboxypeptidase A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1049) at 3 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Cathepsin A/Lysosomal Carboxypeptidase A

Cathepsin A/lyososomal carboxypeptidase A is a member of the serine carboxypeptidase family (1). Cathepsin A is a multifunctional enzyme that expresses deaminidase and esterase activities at neutral pH and carboxypeptidase activity at acidic pH. Also known as protective protein, its association with beta -galactosidase ( beta -gal) and neuraminidase is essential for beta -gal stability and neuraminidase activation in the lysosomes. Inherited deficiency of Cathepsin A causes the lysosomal storage disorder galactosialidosis, characterized by a combined secondary deficiency of beta -gal and neuraminidase. Cathepsin A is capable of hydrolyzing a variety of bioactive peptide hormones including tachykinins, indicating that extralysosomal Cathepsin A plays a role in regulation of functions of these molecules (2). Cathepsin A is synthesized as a single-chain precursor and processed into heavy (32 kDa) and light (20 kDa) chains, which are linked by disulfide bonds.
