標靶描述

Cathepsin B (UniProt: P07858; also known as EC:3.4.22.1, APP secretase, APPS, Cathepsin B1) is encoded by the CTSB (also known as CPSB) gene (Gene ID: 1508) in human. Cathepsin B is a dimeric thiol protease consisting of a light chain (aa 80-126) and a heavy chain (aa 129-333) and is synthesized as a proenzyme of 339 amino acids. It is synthesized with a signal peptide (aa 1-17) that directs it to the lumen of rough endoplasmic reticulum where the signal peptide is removed to generate the inactive procathepsin B with a propeptide sequence (aa 334-339). The propeptide functions as an inhibitor and stabilizes the enzyme. Procathepsin B is shuttled to the Golgi apparatus where it undergoes glycosylation at two asparagine residues. It is subsequently transported to lysosomes where under acidic conditions it undergoes autocatalytic activation following the activation peptide (aa 18-79) and propeptide (aa 334-339). Cathepsin B is a bilobal protein and its catalytic site is located at the interface between the two lobes. The amino acids cysteine, histidine and aspartic acid comprise the catalytic triad of the enzyme, with cysteine on the left lobe interacting with histidine on the right lobe to catalyze peptide bond cleavage. In contrast to other cysteine cathepsins of the papain-like family, it exhibits both endopeptidase and exopeptidase activity. It hydrolyzes proteins with broad specificity and preferentially cleaves Arg-Arg-|-Xaa bonds. Its expression is elevated in several human cancers at the mRNA, protein, and activity levels. It is also frequently overexpressed in premalignant lesions. During the transition to malignancy, cathepsin B localizes to the cell periphery and at the basal pole of polarized cells and active cathepsin B is secreted from tumors and facilitates in invasion and metastasis. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

外觀

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

重構

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

儲存和穩定性

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
