CD200 蛋白, Human (HEK293, His)

CD200 Protein stimulates T-cell proliferation and regulates myeloid cell activity in tissues. It interacts with CD200R1 through their Ig-like domains, indicating its role in immune response modulation and maintaining cellular homeostasis. CD200 Protein, Human (HEK293, His) is the recombinant human-derived CD200 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of CD200 Protein, Human (HEK293, His) is 202 a.a., with molecular weight of 35-50 kDa.

CD200 蛋白是 T 细胞增殖的有效共刺激剂，并参与调节各种组织中的骨髓细胞活性。它与 CD200R1 的功能相互作用是通过 N 端 Ig 样结构域的相互作用来促进的，这表明在调节免疫反应和维持不同细胞环境中的稳态方面发挥着关键作用。

35-50 kDa

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

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150 mM NaCl, 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.
