Recombinant Human IL-15RA/CD215 Protein (RP01192)

Product name	Recombinant Human IL-15RA/CD215 Protein
Catalog No.	RP01192
Description	Recombinant Human IL-15RA/CD215 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Met1-Thr205) of human IL-15R alpha/CD215 (Accession #NP_002180.1) fused with a Fc, 6×His tag at the C-terminus.
Bio-Activity	Measured by its binding ability in a functional ELISA. Immobilized recombinant Human IL15 at 2 μg/mL (100 μL/well) can bind recombinant Human IL-15R alpha, the EC₅₀ of Human IL-15R alpha is 178.9 ng/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	48.40 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.
