Two-color flow cytometric analysis of human BTN3 (CD277) expression on human peripheral blood lymphocytes. Human whole blood was stained with APC Mouse Anti-Human CD3 antibody (Cat. No. 555335/561810/561811) and either PE Mouse IgG2a, κ Isotype Control (Cat. No. 553457; Left Plot) or PE Mouse Anti-Human CD277 antibody (Cat. No. 566006; Right Plot). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). Two-color flow cytometric contour plots showing the correlated expression of BTN3 (CD277) [or Ig Isotype control staining] versus CD3 were derived for gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometric analysis was performed using a BD FACSCanto™ II Flow Cytometer System.

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.
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- An isotype control should be used at the same concentration as the antibody of interest.

Antibody Details
232-5
The 232-5 monoclonal antibody specifically recognizes Butyrophilin 3 (BTN3), which is also known as CD277. BTN3 is comprised of three structurally related members, BTN3A1, BTN3A2, and BTN3A3. BTN3 molecules are transmembrane type 1 glycoproteins that belong to the Ig superfamily. The 232-5 antibody recognizes the variable region of the extracellular domains of BTN3 molecules. BTN3 molecules are differentially expressed by T, NKT, B, and NK cells, monocytes, macrophages, dendritic cells, as well as some stem cells and tumor cells. BTN3 expression is decreased upon lymphocyte activation. The extracellular domain of CD277 is structurally related to the B7 family of proteins that regulate T cell activation. A soluble form of the 232-5 antibody can serve as an agonist in BTN3-mediated regulation of anti-CD3 ± anti-CD28 antibody activated CD4+ or CD8+ T cells.

Format Details
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.
