PSG1 Protein, Human (HEK 293, hFc)

Pregnancy-specific beta-1-glycoprotein 1 (PSG1), originating from the syncytiotrophoblast, attains concentrations of 100 to 290 mg/l in the serum of pregnant women at term. As a vital component of the human placenta, PSG1's molecular characteristics, within the immunoglobulin (Ig) superfamily, contribute to its essential role in supporting pregnancy. With a restricted expression primarily localized to the placenta (RPKM 224.3), PSG1 underscores its significance as a major contributor to the hormonal milieu essential for fetal survival and development during 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.

Pregnancy-specific beta-1-glycoprotein 1 (PSG1) is a prominent constituent of the human placenta, a vital endocrine organ crucial for sustaining fetal well-being. Originating from the syncytiotrophoblast, PSG1 attains concentrations of 100 to 290 mg/l in the serum of pregnant women at term. Classified within the immunoglobulin (Ig) superfamily, PSG1's molecular characteristics contribute to its essential role in supporting pregnancy. With a restricted expression primarily localized to the placenta (RPKM 224.3), PSG1 underscores its significance as a major contributor to the hormonal milieu essential for fetal survival and development during pregnancy.

Approximately 95 kDa.

• 
  Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder

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.
