PE Rat Anti-Mouse CD127
Expression of CD127 (IL-7Rá) in the bone marrow. BALB/c bone marrow leukocytes were stained with either PE-conjugated rat IgG2b, κ isotype control mAb A95-1 (Cat. No. 553989, left panel) or PE-conjugated  mAb SB/199 (right panel) and a cocktail of FITC-conjugated antibodies to the lineage markers CD3e (mAb 145-2C11, Cat.

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 with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

Recommended Assay Procedures

Note: Investigators are highly encouraged to titrate the antibody up to saturating levels for optimal performance, minimizing the risk for dim staining.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  5. An isotype control should be used at the same concentration as the antibody of interest.

SB/199

The SB/199 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 effects 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. IL-7Rα is expressed on common lymphoid progenitors and early stages of B lineage development in the bone marrow, on the earliest thymocyte progenitors, on CD4-CD8- double-negative and CD4+ and CD8+ single-positive thymocytes, and on most peripheral T lymphocytes. Intestinal intraepithelial lymphocytes with low-density γδ TCR expression upregulate CD127 expression in response to IL-2, which may be secreted by neighboring αβ TCR+ T cells.

PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
