          Product Specific Information

          Description: The eBioRDR5 monoclonal antibody reacts with human CD127 (Interleukin-7 Receptor alpha). CD127 complexes with CD132, also known as the common gamma chain (gamma c), to form the multi-functional IL-7 receptor (IL-7R). CD127 is a type I glycoprotein with a molecular weight of 75-80 kDa and is expressed by immature B cells through the early pre-B stage, by thymocytes during several stages of their development, and on most mature T cells, with transient down-regulation upon activation. Binding of IL-7 results in signal transduction which occurs through several tyrosine kinase pathways including the Jak/STAT pathway. IL-7 is indispensable for the development of lymphocytes, and the control of homeostatic proliferation of T-cells in the periphery. In addition, IL-7R signaling is known to be involved in the regulation of T cell receptor (TCR) locus rearrangement in gamma delta T cells.

          Interestingly, it has been demonstrated that CD127 expression is down-regulated on CD4+CD25+ regulatory T cells (Tregs). While the co-expression of CD4 and CD25 has become widely used as an indicator of Tregs, this method of identification may also include cells without suppressive activity. It has clearly been shown that CD4+CD25+ cells that have down-regulated the expression of CD127 are significantly more highly-enriched for the regulatory T population, as defined by expression of the Treg-specific transcription factor Foxp3 and the suppressive activity of these cells, in vitro.

          Binding of the eBioRDR5 monoclonal antibody to PBMCs is blocked by pre-incubation of the cells with recombinant human IL-7 (Product # 14-1079-80).

          Applications Reported: This eBioRDR5 antibody has been reported for use in flow cytometric analysis.

          Applications Tested: This eBioRDR5 antibody has been pre-diluted and tested by flow cytometric analysis of normal human peripheral blood cells. This may 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.

          Alexa Fluor 561 emits at 575 nm and is intended for use on spectral cytometers where it may be multiplexed with both PE and PE-eFluor 610.

          Excitation: 558 nm; Emission: 575 nm; Laser: Yellow-Green Laser.

          Target Information

          CD127, also known as the Interleukin-7 receptor alpha chain (IL-7Ralpha), is a type I glycoprotein with a molecular weight of 75-80 kDa. It forms a multi-functional receptor complex with CD132, the common gamma chain, to create the IL-7 receptor (IL-7R), which is crucial for lymphopoiesis. The active IL-7 receptor is an alpha/gamma chain heterodimer, where the gamma chain also associates with the interleukin-2 receptor and primarily activates signal transduction, while the alpha chain determines specific signaling events through its association with cytoplasmic signaling molecules. CD127 is expressed by immature B cells through the early pre-B stage, thymocytes during various stages of development, and most mature T cells, with transient down-regulation upon activation. It promotes the proliferation of precursor B cells, thymocytes, T cell progenitors, and mature CD4+ and CD8+ T cells. Binding of IL-7 to CD127 results in signal transduction through several tyrosine kinase pathways, including the Jak/STAT pathway, and is indispensable for lymphocyte development and the control of homeostatic proliferation of T cells in the periphery. Additionally, IL-7R signaling is involved in the regulation of T cell receptor (TCR) locus rearrangement in gamma delta T cells. Interestingly, CD127 expression is down-regulated on CD4+CD25+ regulatory T cells (T regs). While CD4 and CD25 co-expression is commonly used to identify T regs, this method may include cells without suppressive activity. CD4+CD25+ cells that have down-regulated CD127 expression are significantly enriched for the regulatory T cell population, as defined by the expression of the T reg-specific transcription factor Foxp3 and their suppressive activity in vitro. Diseases associated with CD127 dysfunction include severe combined immunodeficiency and T cell negative/B cell negative/NK positive severe combined immunodeficiency.
