Synonyms :  Interleukin-15
Host :  CHO cell
Sequence :  The extracellular domain of human IL-15(NP_751914.1)(Asn49-Ser162)including mutations at Q149D and Q156D is fused to the N-terminus of the Fc region of human IgG1.
Molecular Mass :  41 KDa (monomer)
Purity :  >98%，by SDS-PAGE under reducing conditions. 
Endotoxin Content :  <0.06 EU/μg as determined by LAL test.

Activity :  This mutant IL-15/Fc fusion protein specifically binds to the IL-15R, competitively inhibits IL-15-triggered cell  proliferation, promotes transplant tolerance, does not activate the STAT -signaling pathway, and exerts a prolonged circulating half-life caused by the modified Fc domain. 
Formulation :  Lyophilized from 0.2μm-filtered solution in PBS.
Reconstitution :  Reconstitute at 100μg/ml in sterile PBS.
Use / Stability :
Stable for at least 1 year after receipt when stored at -20°C. Working aliquots are 
stable for up to 3 months when stored at -20°C.
Avoid freeze/thaw cycles.
