Scientific Data Images for Human Cathepsin V Antibody

Cathepsin V in Human Breast Cancer Tissue.

Cathepsin V was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using 1.7 µg/mL Goat Anti-Human Cathepsin V Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1080) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Applications for Human Cathepsin V Antibody

Application

Recommended Usage

Immunohistochemistry

5-15 µg/mL
Sample: Immersion fixed paraffin-embedded sections of human breast cancer tissue

Western Blot

0.1 µg/mL
Sample: Recombinant Human Cathepsin V (Catalog # 1080-CY)

Neutralization

Measured by its ability to neutralize Recombinant Human Cathepsin V (0.5 µg/mL, Catalog # 1080-CY) cleavage of the fluorogenic peptide substrate Z-LR-AMC (10 µM, Catalog # ES008). The Neutralization Dose (ND₅₀) is typically 2.2 µg/mL.

Background: Cathepsin V

Cathepsin V (also known as Cathepsin L2 and U) is a cysteine protease of the papain family (1). It is expressed as a proenzyme in lysosomes, which can be autocatalytically converted to the mature form at pH 4.0 (2). Cathepsin V shows high amino acid identity with Cathepsin L (77% for the proenzymes and 80% for the mature enzymes) (3). However, Cathepsin V is specifically expressed in the thymus, testis, and corneal epithelium whereas Cathepsin L is expressed throughout the body.
