XG/Xg blood group Protein, Human (HEK293, His)

XG/Xg blood group Protein is a type I transmembrane glycoprotein belonging to the CD99 family. It is a erythrocyte membrane protein that is used as the basis of the Xg blood group system. XG/Xg blood group Protein, Human (HEK293, His) is the recombinant human-derived XG/Xg blood group protein, expressed by HEK293 , with C-His labeled tag. The total length of XG/Xg blood group Protein, Human (HEK293, His) is 122 a.a., with molecular weight of ~14.6 kDa.

Lyophilized powder

Lyophilized from a 0.2 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.
