PE Mouse Anti-Human Basophils (2D7)
Multiparameter flow cytometric analysis of Basophils (2D7) expression on human peripheral blood leucocyte populations. Human whole blood was fixed with BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049) and permeabilized with BD Phosflow™  Perm/Wash Buffer I (Cat. No. 557885), and the cells were then stained with either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; Left Plot) or PE Mouse Anti-Human Basophils (2D7)antibody (Cat. No. 568076/568077; Right Plot). The bivariate pseudocolor density plot showing the correlated expression of Basophils (2D7) [or Ig Isotype control staining] versus side light-scatter (SSC-A) signals was derived from gated events with the forward and side light-scatter characteristics of intact leucocyte populations. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

No. 562570) and then fixed with BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049) and permeabilized with BD Phosflow™  Perm/Wash Buffer I (Cat. No. 557885).

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.

2D7/BASO

The 2D7 monoclonal antibody selectively recognizes human basophils, Basophils (2D7). The antibody binds to a ~7.2 to 7.5 kDa basophil-specific protein, also known as the 2D7 antigen or ligand, present in secretory granules which has not been conclusively identified. Basophils normally comprise a relatively small percentage (<1%) of total peripheral blood leucocytes. Basophils express high levels of FceRI, a high affinity receptor for IgE. Upon activation through crosslinking of FceRI, basophils degranulate and may thus show reduced staining with the 2D7 antibody due to the release or destruction of the 2D7 antigen.  The activated basophils release proinflammatory mediators that can either counter parasitic infections or lead to acute or chronic allergic diseases, including anaphylaxis, asthma, and atopic dermatitis. Activated basophils release a variety of mediators including the vasodilator histamine, proteolytic enzymes, and several cytokines which promote inflammation as well as heparin which  prevents blood clotting. The 2D7 monoclonal antibody is useful for identifying human basophils since it does not recognize lymphocytes, monocytes, eosinophils, neutrophils, or mast 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.
