免疫原
Human IL-7R Recombinant Protein
简单描述
The hIL-7R-M21 monoclonal antibody specifically binds to the 60-90 kDa glycoprotein, CD127. CD127 is also known as the IL-7 receptor alpha (IL-7Rα) subunit. The IL-7 receptor complex is a heterodimer composed of CD127 and the common gamma chain (γc, CD132), shared by other cytokine receptors (IL-2R, IL-4R, IL-9R, IL-15R, and IL-21R). CD127 is expressed on thymocytes, T- and B-cell progenitors, mature T cells, and some lymphoid and myeloid cells. In vitro experiments show the expression of CD127 is down-regulated following T cell activation. Studies indicate that the IL-7 Receptor plays an important role in the proliferation and differentiation of mature T cells. Recently, it has been shown that low surface expression of CD127, in combination with intermediate to high surface expression of CD25, the α chain of the IL-2 receptor complex, can distinguish between human regulatory and conventional CD4+ T cells in human adult and cord blood, lymph nodes and thymus.

PE-Cy7
PE-Cy7 dye is a part of the BD PE family of dyes. This tandem fluorochrome is comprised of a R-Phycoerythrin (PE) donor that has excitation maxima (Ex Max) of 496-nm and 566-nm and an acceptor dye, Cy™7, with an emission maximum (Em Max) at 781-nm. PE can be excited by the Blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and detected using an optical filter centered near 781 nm (e.g., a 760/60-nm bandpass filter). The donor dye can be excited by the Blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and the acceptor dye can be excited by the Red (627–640-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Flow cytometric analysis of CD127 (IL-7Rα) expression on human peripheral blood lymphocytes. Whole blood was stained with PE-Cy™7 Mouse Anti-Human CD127 antibody (Cat. No. 560822; solid line histogram) or with a PE-Cy™7 Mouse IgG1, κ Isotype Control (Cat. No. 557872; dotted line histogram). The erythrocytes were lysed with BD PharmLyse™ Lysing Buffer (Cat. No. 555899). The fluorescence histograms were derived from events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometry was performed using a BD™ LSR II Flow Cytometer System.
