Recombinant Human IL-2Rβ Protein(C-Fc)

Recombinant Human IL-2 receptor beta is produced by our Mammalian expression system and the target gene encoding Ala27-Asp239 is expressed with a Fc tag at the C-terminus.

Lyophilized from a 0.2 μm filtered solution of PBS,pH7.4.

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.

C-Fc

Greater than 95% as determined by reducing SDS-PAGE.

Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.

Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Human IL-2RB, also known asinterleukin-2 receptor subunit beta,is the receptor for interleukin-2. IL2 receptor complex is involved in receptor mediated endocytosis and transduces the mitogenic signals of IL2. IL2 receptor complex has three forms with respect to ability to bind IL2. IL-2RB is belonged to a type I membrane protein,and has a 26 residue signal peptide, a 214 residue extracellular region, a 25 residue transmembrane region and a 286 residue cytoplasmic domain. IL-2RB is the subunit critical for receptor-mediated signaling via physically or functionally coupling to other signaling molecules, such as the Jak-STAT and Src-family protein tyrosine kinase although it lacks apparent catalytic motifs.
