Recombinant Human IL-15 Protein (RP01236)

Product name	Recombinant Human IL-15 Protein
Catalog No.	RP01236
Description	Recombinant Human IL-15 Protein is produced by E. coli expression system. The target protein is expressed with sequence (Asn49-Ser162) of human IL-15 (Accession #NP_000576.1) fused with a 6×His tag at the C-terminus.
Bio-Activity	Measured in a cell proliferation assay using HT-2 cells. The ED₅₀ for this effect is 1.5-5 pg/mL, corresponding to a specific activity of 2.0×10⁸-6.67×10⁸units/mg.
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	13.61 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.
