Cathepsin B 蛋白, Rat (HEK293, His)

Cathepsin B is a lysosomal cysteine protease that plays a role in intracellular protein catabolism. Cathepsin B mediates JNK signaling pathway to regulate the migration of glioma initiation cells. Cathepsin B is involved in the pathology of chronic inflammatory diseases of the airway and joints, as well as cancer and pancreatitis. Cathepsin B Protein, Rat (HEK293, His) is the recombinant rat-derived Cathepsin B protein, expressed by HEK293 , with C-His labeled tag. The total length of Cathepsin B Protein, Rat (HEK293, His) is 322 a.a., with molecular weight of 35-43 kDa.

组织蛋白酶 B 是一种溶酶体半胱氨酸蛋白酶，在细胞内蛋白质分解代谢中起作用，参与其他生理过程，如免疫应答中的抗原加工、激素激活和骨转换。组织蛋白酶 B 介导 JNK 信号通路调节胶质瘤起始细胞的迁移。组织蛋白酶 B 可以增强其他蛋白酶的活性，包括基质金属蛋白酶、尿激酶 (丝氨酸蛋白酶尿激酶纤溶酶原激活剂) 和 Cathepsin D。组织蛋白酶 B 参与气道和关节慢性炎症性疾病的病理，以及癌症和胰腺炎。

Measured by its ability to cleave the fluorogenic peptide substrate Z-LR-AMC . The specific activity is >2,500 pmol/min/μg.

无菌粉末

Lyophilized from a 0.2 μm filtered solution of 25 mM Tris, 150 mM NaCl, pH 7.5. or PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
