TGFBR2/TGF-beta RII 蛋白, Human (HEK293, Fc)

TGF-beta receptor 2 Protein, Human (HEK293, Fc), a fragment of transforming growth factor-beta receptor type 2 (TβRII), consists of amino acid of Thr23-Asp159 with an Fc tag at the C-terminus.

2 型转化生长因子-β 受体 (TβRII) 是一种 567 个氨基酸的单通道 I 型膜蛋白，包含一个蛋白激酶结构域。TβRII 是 TGFβ 配体的特异性受体，对于肿瘤发生、进展和转移中 TGFβ 信号传导的调节至关重要^[1]。T beta R-II（转化生长因子 β [TGF-β] II 型受体）是一种跨膜丝氨酸/苏氨酸激酶，充当主要 TGF-β 受体。配体与 T beta R-II 结合会导致 T beta RI 的募集和磷酸化，T beta RI 是一种远缘跨膜激酶，充当下游信号传导组件^[2]。

Measured by its ability to inhibit TGF-beta 1 activity on HT-2 mouse T cells. The ED₅₀ this effect is 3.527 μg/mL in the presence of 0.25 ng/mL of recombinant human TGF-beta 1, corresponding to a specific activity is 283.527 units/mg.

Approximately 55-75 kDa

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

无菌粉末.

Lyophilized after extensive dialysis against 20 mM PB, 150 mM NaCl, pH 7.4 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. 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.
