Molecular Weight Recombinant Human IL2RB has a calculated molecular mass of 25 kDa. Due to the abundant glycosylation, it migrates as approximately 35 kDa protein bands in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions.
Purification His-tag affinity purification by immobilized metal ion affinity chromatography (IMAC)

Stability & Storage

Ice packs
Upon arrival, the lyophilized protein may be stored for 2 weeks at 4°C. For long term storage, it is recommended to store desiccated below -20 °C in a manual defrost freezer. Following reconstitution, the protein may be stored for 2 weeks under sterile conditions at -20 °C.  For long term storage, it is recommended to make appropriate aliquots and store at -80 °C. Avoid repeated freeze-thaw cycles.
