Description

Mouse Monoclonal Antibody

Description: This 2SX21R monoclonal antibody reacts with human CD360 (Interleukin-21 Receptor, IL-21R). IL-21R forms a heterodimeric receptor complex with the common gamma chain to form a functional receptor for IL-21. IL-21 is a class I cytokine of the common gamma chain family of cytokines and signals through the IL-21R complex to activate the JAK/STAT (Janus Kinase/Signal Transducers and Activators of Transcription) signaling pathway. Activation of the JAK/STAT pathway by IL-21 promotes transcription of genes responsive to STAT1 and STAT3. IL-21 is mainly produced by CD4+ T cells and mediates the proliferation, differentiation, and effector functions of cells expressing IL-21R such as B cells, T cells, NK cells, dendritic cells and other populations of myeloid cells. IL-21 and its receptor are implicated in the pathogenesis of chronic viral infections, autoimmunity, allergy, organ transplantation, and cancer. Applications Reported: This 2SX21R antibody has been reported for use in flow cytometric analysis. Applications Tested: This 2SX21R antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.25 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

The 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.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

Our options will depend on the samples you are analyzing.

If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.

For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.

Can the eFluor Organic fluorochromes be used for intracellular staining?

Yes, the eFluor Organic fluorochromes can be used for intracellular staining. The eFluor organic fluorochromes maintain bright signal and require minimal changes in compensation when fixed with eBioscience IC Fixation Buffer (Cat. No. 00-8222-49) and Permeabilization Buffer (Cat. No. 00-8333-56) or 1-step Fix/Lyse Solution (Cat. No. 00-5333-54, 00-5333-57) (as compared to live cells).
