Shipping Temperature	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Storage Conditions	Store it under sterile conditions at -20C to -80C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Antigen molecule name	IL2RB
Protein Construction	The mature form of human IL2 Rbeta (NP_000869.1) extracellular domain (Met 1-Asp 239) with five amino acids (DDDDK) at the C-terminus was expressed and purified.
Expressed Host	Human Cells
Bio-Activity	1. Measured by its binding ability in a functional ELISA. Immobilized human IL2Rb at 10 ug/ml (100 ul/well) can bind biotinylated human IL2 (Cat:11848-HNAE), The EC50 of biotinylated human IL2 (Cat:11848-HNAE) is 0.1-0.24 ug/mL. 2. Measured by its ability to inhibit IL15-dependent proliferation of MO7e human megakaryocytic leukemic cells in the presence of 4.0 ng/mL of recombinant human IL-15. The ED50 for this effect is 1-4ug/mL.
Endotoxin	< 1.0 EU per ug of the protein as determined by the LAL method
Predicted N Terminal	Ala 27
Molecule Mass	The mature recombinant human IL2 Rbeta consists of 219 amino acids and has a predicted molecular mass of 25.2 kDa. As a result of glycosylation, the rh IL2 Rbeta migrates as an approximately 40 kDa protein in SDS-PAGE under reducing conditions.
Formulation	Lyophilized from sterile 100mM NaCl, 50mM Tris, pH 7.5
