PSG1 Protein, Human (HEK293, His)

PSG1 Protein is extremely vital to development and health of a fetus. PSG1 Protein is important in inducing, enhancing or inhibiting an immune response^[1][2]. PSG1 Protein, Human (HEK293, His) is the recombinant human-derived PSG1 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of PSG1 Protein, Human (HEK293, His) is 385 a.a., with molecular weight of ~68 kDa.

PSG1 Protein is a secreted glycoprotein of the human PSG family^[3]. PSG1 Protein is the most abundant PSG in maternal serum, as a possible inducer of proangiogenic growth factors known to play an important role in establishment of the vasculature at the maternal-fetal interface^[4]. PSG1 Protein functions primarily as an immune-modulator to protect the growing fetus^[5].

Approximately 68 kDa

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

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM 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.
