BV421 Rat Anti-Mouse CD127
BV421 Rat Anti-Mouse CD127
Two-color flow cytometric analysis of CD127 expression on Mouse spleen cells. Splenic leucocytes from a C57BL/6 Mouse were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) [Cat. No. 553141/553142]. The cells were then stained with Alexa Fluor® 647 Rat Anti-Mouse CD3 antibody (Cat. No. 557869) and either BD Horizon™ BV421 Rat IgG2a, k Isotype Control (Cat. No. 562602; Left Plot) or BD Horizon™ BV421 Rat Anti-Mouse CD127 antibody (Cat. No. 566377; Right Plot) at 0.5 μg/test. Two-color flow cytometric contour plots showing the correlated expression of CD127 (or Ig Isotype control staining) versus CD3, were derived from gated events with the forward and side light-scatter characteristics of viable leucocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ X-20 Flow Cytometer System. Data shown on this Technical Data Sheet are not lot specific.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unconjugated antibody and free dye were removed.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation).  When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells.   However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls.  It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime BD Horizon Brilliant dyes are used in a multicolor flow cytometry panel.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

A7R34

The A7R34 monoclonal antibody specifically binds to mouse CD127 which is also known as the Interleukin-7 Receptor alpha chain (IL-7Rα). CD127 associates with CD132 (common γ chain) to form a high-affinity signaling IL-7R complex that mediates the biological functions of IL-7. CD127 can also complex with the Thymic Stromal Lymphopoietin Receptor (TSLPR) subunit to bind and mediate cellular responses to TSLP. CD127 is a 65-75 kDa type-I transmembrane protein that belongs to the hematopoietin receptor and the Ig gene superfamilies. Mice lacking CD127 display profoundly impaired development of the B and T lymphoid cell lineages, but display no obvious nonlymphoid abnormalities. CD127 is expressed on common lymphoid progenitors and early stages of B lineage development in the bone marrow, the earliest thymocyte progenitors, CD4-CD8- double-negative and CD4+ and CD8+ single-positive thymocytes, naïve and memory T lymphocytes, γδ TCR+ T cells, thymic NK cells, and bone marrow stromal cells. CD127 is downregulated upon activation of naïve T cells and CD127 re-expression identifies effector cells that subsequently differentiate into memory T cells. The A7R34 antibody blocks IL-7 binding to CD127. This antibody has been used in both in vitro and in vivo studies to define the biological roles played by CD127.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
