Recombinant Human CD8a Protein (RP01245)

Product name	Recombinant Human CD8a Protein
Catalog No.	RP01245
Description	Recombinant Human CD8a Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Ser22-Asp182) of human CD8 alpha (Accession #NP_001759.3) fused with a Fc, 6×His tag at the C-terminus.
Bio-Activity	Measured by its binding ability in a functional ELISA. Immobilized Human CD8A at 2μg/mL (100 μL/well) can bind anti Human CD8A antibody with a linear range of 0.1-27.6ng/mL.
Purity	> 95% 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	44.40 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.
