Human Cathepsin V Antibody Summary

Species Reactivity
Human
Specificity
Detects human Cathepsin V in direct ELISAs and Western blots. In direct ELISAs, less than 10% cross-reactivity with recombinant human (rh) Cathepsin C, rhCathepsin S, rhCathepsin H, rhCathepsin F and rhCathepsin L is observed.
Source
Polyclonal Goat IgG
Purification
Antigen Affinity-purified
Immunogen
Mouse myeloma cell line NS0-derived recombinant human Cathepsin V
Val18-Val334
Accession # O60911
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Label
Unconjugated

Applications

Recommended Concentration
Sample
Western Blot
0.1 µg/mL
Recombinant Human Cathepsin V (Catalog # 1080-CY)
Immunohistochemistry
5-15 µg/mL
See below
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.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Scientific Data

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).

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.
