Multiparameter flow cytometric analysis of CD20 expression on human peripheral blood leucocyte populations. Whole blood was stained with either Biotin Mouse IgG2b, κ Isotype Control (Cat. No. 565415/555741; Left Plot) or Biotin Mouse Anti-Human CD20 antibody (Cat. No. 567709; Right Plot) at 0.5 µg/test. The cells were counterstained with PE-Streptavidin (Cat. No. 554061). The erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). The bivariate pseudocolor density plot showing the correlated expression of CD20 (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 FACSymphony™ A5 Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

Preparation And Storage
Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with biotin under optimum conditions, and unreacted biotin was removed.
Product Notices
- 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.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

Antibody Details
2H7
The 2H7 monoclonal antibody specifically binds to CD20, encoded by the MS4A1 (Membrane-spanning 4-domains, subfamily A, member 1) gene. CD20 is a 33-37 kDa, unglycosylated four-transmembrane phosphoprotein. CD20 is expressed on pre-B-cells, resting and activated B cells, and follicular dendritic cells, but not plasma cells. Low level CD20 expression is observed on a small subset of normal circulating T lymphocytes. The CD20 molecule is involved in the regulation of B-cell activation.

Biotin
Biotin is a ubiquitous co-factor (also known as Vitamin B7) that has many properties that make it extremely useful for molecular biology. Biotin has an extremely high affinity for the Avidin family of proteins (Kd = 10-15 M), making it the perfect tool to link two molecules. Biotin labeled antibodies can be combined with any number of Avidin-conjugated probes in order to customize an assay to a particular need. This is especially useful in the case of magnetic cell separation using streptavidin/magnetic bead conjugates, or in the case of flow cytometry using streptavidin/fluorophore conjugates.
