PSG1 蛋白, Human (HEK 293, hFc)

Pregnancy-specific beta-1-glycoprotein 1 (PSG1) is derived from the syncytiotrophoblast and reaches concentrations in the serum of term pregnant women of 100 to 290 mg/l. As an important component of the human placenta, PSG1's molecular signature within the immunoglobulin (Ig) superfamily contributes to its important role in supporting pregnancy. PSG1 Protein, Human (HEK 293, hFc) is the recombinant human-derived PSG1 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of PSG1 Protein, Human (HEK 293, hFc) is 385 a.a., with molecular weight of ~95 KDa.

妊娠特异性 β-1-糖蛋白 1 (PSG1) 是人类胎盘的主要成分，胎盘是维持胎儿健康的重要内分泌器官。PSG1 源自合体滋养层，在足月孕妇的血清中浓度达到 100 至 290 mg/l。PSG1 属于免疫球蛋白 (Ig) 超家族，其分子特征有助于其在支持妊娠方面发挥重要作用。PSG1 的限制性表达主要位于胎盘 (RPKM 224.3)，强调了其作为妊娠期间胎儿生存和发育所必需的激素环境的主要贡献者的重要性。

Lyophilized from a 0.22 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.
