- Description
- 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 (0.5 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. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 µm post-manufacturing filtered.

- 3 FIGURE B cells from older human donors are able to upregulate costimulatory molecules and activation markers after stimulation. (a-e) Representative flow cytometric histograms showing the expression levels of costimulatory molecules by memory B cells from a 29 year old (grey) and 70 year old (blue) donor after 48 h stimulation with CD40L and IL-21 or media (orange) and graphs showing the percentages of cells positive for the marker, or geometric mean of marker using the gating strategies shown, for CD80 (a), CD86 (b), HLA-DR (c), CD69 (d) and IL-21R (e). These were gated on live CD19 + CD20 + cells. Fluorescent minus one (FMO) controls were included for the IL-21R stain and are shown on the representative histogram. Bar height corresponds to the mean, error bars indicate standard deviation, and each symbol represents values from independent donors. Statistics were calculated using the unpaired Mann-Whitney U test. Data were representative of three independent repeat experiments.
