IL-12 R beta 1,IL12RB1,CD212,IL12R,IL12RB,IL-12RB1
Human IL-12 R beta 1, His Tag (ILB-H52H9) is expressed from human 293 cells (HEK293). It contains AA Cys 24 - Glu 540 (Accession # P42701-1).
Predicted N-terminus: Cys 24
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 59.0 kDa. The protein migrates as 66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Immobilized Human IL-12 R beta 1, His Tag (Cat. No. ILB-H52H9) at 2 μg/mL (100 μL/well) can bind Human IL-12B, Fc Tag (Cat. No. NK2-H5258) with a linear range of 0.078-1.25 μg/mL (QC tested).
The human IL-12 R subunit is a member of the cytokine receptor superfamily and the functional high-affinity IL-12R is composed of at least two beta-type cytokine receptor subunits, each independently exhibiting a low affinity for IL-12. IL-12 R beta 1 (Interleukin-12 receptor subunit beta-1) is also known as IL-12RB1, CD212. Functions as an interleukin receptor which binds interleukin-12 with low affinity and is involved in IL12 transduction. Associated with IL12RB2 it forms a functional, high affinity receptor for IL12. Associates also with IL23R to form the interleukin-23 receptor which functions in IL23 signal transduction probably through activation of the Jak-Stat signaling cascade.
