Rabbit polyclonal to IL21 ReceptorThe protein encoded by this gene is a cytokine receptor for interleukin 21 (IL21). It belongs to the type I cytokine receptors, and has been shown to form a heterodimeric receptor complex with the common gamma-chain, a receptor subunit also shared by the receptors for interleukin 2 (IL2) and interleukin 5 (IL5). This receptor transduces the growth promoting signal of IL21, and is important for the proliferation and differentiation of T cells, B cells, and natural killer (NK) cells. The ligand binding of this receptor leads to the activation of multiple downstream signaling molecules, including JAK1, JAK3, STAT1, and STAT3. Knockout studies of a similar gene in mouse suggest a role for this gene in regulating immunoglobulin production. Three alternatively spliced transcript variants encoding the same protein have been described.

Tested Applications
ELISAWB
For ELISA: Use at a concentration of 0.5 - 2 μg/ml. For WB: Use at a concentration of 0.5 - 2 μg/ml. Detects a band of approximately 60 kDa. The 60 kD IL21 Receptor band is detected in 30 ug/lane of whole Raji cell lysate. Bands at 45 kD and 35 kD are also seen. Optimal dilutions/concentrations should be determined by the researcher.:
