Recombinant Human IL15 Protein (Asn 49 - Ser 162)

Cat.No. : IL15-321H
Product Overview : Recombinant Human IL15 Protein is expressed from E.coli cells. It contains AA Asn 49 - Ser 162 (Accession # AAH18149). Predicted N-terminus: Asn 49. This protein carries no "tag". The protein has a calculated MW of 12.8 kDa. The protein migrates as 13 kDa under reducing (R) condition (SDS-PAGE).
Source : E.coli
Species : Human
Form : Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
Bio-activity : Human IL-2 R beta, Fc Tag captured on CM5 chip via anti-human IgG Fc antibody, can bind Recombinant Human IL15 Protein with an affinity constant of 9.5 nM as determined in a SPR assay (Biacore T200) (QC tested).
Recombinant Human IL15 Protein stimulates proliferation of CTLL-2 cells. The ED50 for this effect is 0.097-0.19 ng/ml (Routinely tested).
Molecular Mass : 12.8 kDa
Protein length : Asn 49 - Ser 162
Endotoxin : Less than 0.1 EU per μg by the LAL method.
Purity : >95% as determined by SDS-PAGE.
Notes : Please avoid repeated freeze-thaw cycles.
Stability : No activity loss is observed after storage at:
4-8 centigrade for 12 months in lyophilized state;
-70 centigrade for 3 months under sterile conditions after reconstitution.
Storage : For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
