Mouse IL-2 R beta, His Tag (ILA-M52H5) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Glu 240 (Accession # P16297-1).
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 27.1 kDa. The protein migrates as 42-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 . Normally trehalose is added as protectant before lyophilization.

Interleukin-2 receptor subunit beta (IL2RB) is also known as CD122, which Belongs to the type I cytokine receptor family. Type 4 subfamily. IL2RB contains 1 fibronectin type-III domain. IL2RB / CD122 is involved in T cell-mediated immune responses, is present in 3 forms with respect to ability to bind interleukin 2. The low affinity form is a monomer of the alpha subunit and is not involved in signal transduction. The intermediate affinity form consists of an alpha/beta subunit heterodimer, while the high affinity form consists of an alpha/beta/gamma subunit heterotrimer. Both the intermediate and high affinity forms of the receptor are involved in receptor-mediated endocytosis and transduction of mitogenic signals from interleukin 2.
