BTN2A1 蛋白, Human (HEK293, His)

BTN2A1 Protein, Human (HEK293, His) is a recombinant mouse BTN2A1 produced in HEK293 cells, with His tag. BTN2A1 is a member of butyrophilin family^[1].

属于免疫球蛋白超家族的嗜丁酸蛋白是一种新型的免疫系统调节因子，它们存在于淋巴细胞、树突状细胞、单核细胞、巨噬细胞、中性粒细胞和嗜酸性粒细胞上，并对它们产生刺激和（或）抑制作用^[1].

39-44 kDa

Greater than 95% as determined by reducing SDS-PAGE.

无菌粉末.

Lyophilized after extensive dialysis against PBS, pH7.4.

<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.
