CD127 Monoclonal Antibody (eBioSB/199 (SB/199)), eFluor™ 450, eBioscience™, Invitrogen™

Description

• Description: The SB/199 monoclonal antibody reacts with mouse CD127, the high affinity a subunit of the mouse IL-7 receptor
• IL-7 receptor a chain is expressed by immature B cells in the bone marrow, double-negative (CD4-/CD8-), single-positive (CD4+ and CD8+), but not double-positive (CD4+/CD8+) thymocytes
• In the periphery, mature T cells express low levels of CD127
• Binding of SB/199 blocks the binding of A7R34, another antibody which recognizes mouse CD127
• Applications Reported: This eBioSB/199 (SB/199) antibody has been reported for use in flow cytometric analysis
• Applications Tested: This eBioSB/199 (SB/199) antibody has been tested by flow cytometric analysis of mouse splenocytes
• This can be used at less than or equal to 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
• It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest
• eFluor™ 450 is an alternative to Pacific Blue™
• eFluor™ 450 emits at 445 nm and is excited with the Violet laser (405 nm)
• Please make sure that your instrument is capable of detecting this fluorochome
• Excitation: 405 nm; Emission: 445 nm; Laser: Violet Laser
• Filtration: 0.2 μm post-manufacturing filtered
• CD127 (Interleukin-7, IL-7) is a glycoprotein involved in the regulation of lymphopoiesis
• The response of cells to CD127 is dependent on the presence of the interleukin 7 receptor (IL7R); the active receptor is an alpha/gamma chain heterodimer
• CD127 consists of an alpha chain and a gamma chain
• The gamma(c) chain, which also associates with the interleukin-2 receptor, serves primarily to activate signal transduction by the IL7R complex, while the alpha chain of IL7R determines specific signaling events through its association with cytoplasmic signaling molecules
• CD127 promotes the proliferation of precursor B cells, thymocytes, T cell progenitors, and mature CD4+ and CD8+ T cells
• The biological effects of IL7 are mediated by the binding of IL7 to the specific cell surface receptor
• Diseases associated with CD127 dysfunction include severe combined immunodeficiency and T cell negative/B cell negative/NK positive severe combined immunodeficiency.
