Recombinant Human B7-H2/ICOSLG/CD275 Protein (RP01163)

Product name	Recombinant Human B7-H2/ICOSLG/CD275 Protein
Catalog No.	RP01163
Description	Recombinant Human B7-H2/ICOSLG/CD275 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Asp19-Ser258) of human B7-H2/ICOSLG (Accession #NP_056074.1) fused with a 6×His tag at the C-terminus.
Bio-Activity	Measured by its binding ability in a functional ELISA. Immobilized Human B7-H2/ICOSLG at 1 μg/mL (100 μL/well) can bind Human ICOS/CD278 with a linear range of 2-14.8 ng/mL.
Purity	> 90% by SDS-PAGE.
Endotoxin	< 0.1 EU/μg of the protein by LAL method.
Formulation	Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
Species	Human
Calculated MW	27.53 kDa

Storage	Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Reconstitution	Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
