Human ULBP-4 Protein (ULB-HM204) Summary

Product Description	Recombinant Human ULBP-4 Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains His31-Asp225.
Product Background	UL16-binding proteins (ULBPs) are markers of cellular stress which are upregulated on the surface of virus-infected and tumor cells. ULBPs are expressed by a variety of leukemias, carcinomas, melanomas, and tumor cell lines.ULBP4 is associated with higher levels of CD8+/NKG2D+ lymphocytes infiltrating the carcinoma and is a prognosticator of improved survival.

Product Tag	C-hFc
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
