Cathepsin H 蛋白, Mouse (HEK293, His)

Cathepsin H Protein, Mouse (HEK293, His) is an approximately 36-40 kDa cathepsin H protein with a His-flag. Cathepsin H is a lysosomal cysteine protease of the papain family^[1].

组织蛋白酶 H 是一种溶酶体半胱氨酸蛋白酶，属于木瓜蛋白酶家族。组织蛋白酶 H 被合成为前体蛋白，由信号肽（残基 120）、前肽（残基 21-95）、短链（残基 96-103）、重链（残基 114-290）和轻链组成。链（残基 291-333）^[1]。

Measured by its ability to cleave the fluorogenic peptide substrate, Arg-7-amido-4-methylcoumarin (R-AMC). The specific activity is >700 pmol/min/μg.

无菌粉末

Lyophilized from a 0.2 μm filtered solution of 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. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

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.
