IFN-alpha 10/IFNA10 蛋白, Human (HEK293, His)

IFN-alpha 10 (IFNA10), belongs to type I interferon family, is produced by macrophages with antiviral activities^[1]. IFN-alpha 10/IFNA10 Protein, Human (HEK293, His) contains 189 a.a. (M1-D189), produced in HEK293 cells with a C-terminal His-tag.

IFN-α 10（IFNA10；IFN-α10）属于 α/β 干扰素 (IFN) 家族，由巨噬细胞产生，具有抗病毒活性^[1]。干扰素（IFN）最初被认为是一种在体外“干扰”病毒复制的物质。IFN-α/β及相关分子被归类为I型干扰素，其他两类分别为II型干扰素（IFN-γ）和III型干扰素（IFN-λ）^[2]。
干扰素刺激两种酶的产生：蛋白激酶和寡腺苷酸合成酶。干扰素α（IFNa）在多种癌症，尤其是毛细胞白血病、慢性粒细胞白血病等血液系统恶性肿瘤中表现出显着的生物活性^[3]。
IFNα-10参与JAK/STAT信号通路具有强信号传导效应 (EC₅₀=0.3 nM)，被认为是有效的调节剂，可降低 CTLA4 和 FOXP3 而不影响细胞活力。因此，调节性T细胞（Treg）作为调节外周自身反应性T淋巴细胞的关键细胞，IFNα-10调节Treg功能状态并破坏Treg^[4]。

IFN-alpha 1 (1^-11-1^-6 M; 24-26 h) results signifcant reduction of both CTLA4 and FOXP3 gene expression in regulatory T cells (Tregs) without affecting cell viability^[4].

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.
