CSTL1 蛋白, Human (HEK293, Fc)

Cystatin-like protein 1 (CSTL1) is a member of the cystatin family. CSTL1 Protein, Human (HEK293, Fc) is the recombinant human-derived CSTL1 protein, expressed by HEK293 , with C-hFc labeled tag.

CSTL1 蛋白是一种 2 型半胱氨酸蛋白酶抑制剂样蛋白。2 型胱抑素蛋白是一类半胱氨酸蛋白酶抑制剂，存在于多种人体体液和分泌物中。该蛋白质的具体功能尚未确定。半胱氨酸蛋白酶抑制剂超家族包括含有多个半胱氨酸蛋白酶抑制剂样序列的蛋白质。超家族中有3个抑制家族，包括1型半胱氨酸蛋白酶抑制剂（stefins）、2型半胱氨酸蛋白酶抑制剂和激肽原。

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.
