Protocol
Specificity / Sensitivity
Cathepsin B (D1C7Y) XP® Rabbit mAb recognizes endogenous levels of total cathepsin B protein. This antibody detects the heavy chain subunit of cathepsin B.
Species Reactivity:
Human, Mouse, Rat
Source / Purification
Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the heavy chain subunit of human cathepsin B protein.
Background
Cathepsin B (CSTB), part of the papain family of proteases, is a widely expressed lysosomal cysteine endopeptidase (1,2). Cathepsin B is produced from a larger precursor form, pro-cathepsin B, which runs at approximately 44 kDa on SDS-PAGE, and is proteolytically processed and glycosylated to form a mature two-chain protein containing a heavy chain (running at 27 and 24 kDa) and a light chain (5 kDa). High levels of cathepsin B are found in macrophages and osteoclasts, as well as various types of cancer cells, including lung, colon, prostate, breast, and stomach. In addition, expression of cathepsin B has been associated with multiple sclerosis (3), rheumatoid arthritis (4), and pancreatitis (5). While generally localized to lysosomes, in cancer alterations can lead to its secretion (6). Its role in tumor progression is thought to involve promotion of basement membrane degradation, invasion and metastasis (7,8). Expression can correlate with poor prognosis for a variety of forms of cancer (9-13).
