Product Specific Information
Alexa Fluor™ Plus recombinant antibodies are conjugated using new, proprietary dye chemistry so you can generate stunning data. Alexa Fluor™ Plus antibodies represent an advancement in fluorescent conjugate technology. Alexa Fluor™ Plus antibodies provide brighter signal compared to leading Alexa Fluor™ antibodies, providing you with better signal-to-noise for your critical experiments. These antibodies show better specificity and lot-to-lot consistency as these are recombinant antibodies, generated by cloning specific genes for the desired antibodies into an expression vector and expressed in vitro.
Using conjugate solutions: Centrifuge the protein conjugate solution briefly in a microcentrifuge before use; add only the supernatant to the experiment. This step will help eliminate any protein aggregates that may have formed during storage, thereby reducing nonspecific background staining.
Applications Tested: This eBioRDR5 antibody has been tested by flow cytometric analysis of normal human peripheral blood cells and HEK293 overexpression cells. 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.
Excitation: 494 nm; Emission: 519 nm; Laser: Blue Laser
Filtration: 0.2 µm post-manufacturing filtered.
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.
