目标/特异性 | Detects mouse Cathepsin B in direct ELISAs and Western blots. In direct ELISAs, approximately 25% cross-reactivity with recombinant human Cathepsin B is observed and less than 5% cross-reactivity with recombinant mouse (rm) Cathepsin A, rmCathepsin C, and rmCathepsin D is observed. |
使用方法 | Western Blot: 0.1 µg/mL Immunohistochemistry: 5-15 µg/mL Neutralization: Measured by its ability to neutralize Recombinant Mouse Cathepsin B (0.1 µg/mL, Catalog # 965-CY) cleavage of the fluorogenic peptide substrate Z-LR-AMC (10 µM, Catalog # ES008). The Neutralization Dose (ND50) is typically 0.33 µg/mL. |

背景 | Cathepsin B is the first described member of the family of lysosomal cysteine proteases (1). Cathepsin B possesses both endopeptidase and exopeptidase activities, in the latter case acting as a peptidyl-dipeptidase. It is known to process a number of proteins, including pro and active caspases, prorenin and secretory leucoprotease inhibitor (SLPI) (2‑4). Therefore, Cathepsin B may play a role in activation and inactivation of caspases, activation of renin and inactivation of SLPI, the key steps in apoptosis, angiotensin production, and progression of emphysema, respectively. Because of its increased levels and redistribution in human and animal tumors, Cathepsin B may also have a role in invasion and metastasis (5). In addition to the lysosome, Cathepsin B can be secreted or associated with plasma membrane, cytoplasm, and nucleus. It is synthesized as a preproenzyme. Following removal of the signal peptide, the inactive proenzyme undergoes further modifications including removal of the pro region to result in the active enzyme (5). |

Cathepsin B in Mouse Thymus. Cathepsin B was detected in perfusion fixed frozen sections of mouse thymus using 5 µg/mL Goat Anti-Mouse Cathepsin B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF965) 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).
