PE Mouse Anti-Human CD21

BD Pharmingen™ PE Mouse Anti-Human CD21

Name: PE Mouse Anti-Human CD21
Brand: BD Pharmingen™
SKU: 555422

Clone B-ly4

(RUO)

Flow cytometric analysis of CD21 expression on human peripheral blood lymphocytes. Whole blood was stained with either PE Mouse Anti-Human CD21 (Cat. No. 555422/557327/561768; solid line histogram) or PE Mouse IgG1 κ Isotype Control (Cat. No. 555749; dashed line histogram). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). Fluorescent histograms were derived from gated events with the side and forward light-scattering characteristics of viable lymphocytes. Flow cytometry was performed on a BD FACSCan™ system.

Reactivity: Human (QC Testing), Rhesus, Cynomolgus, Baboon, Pig (Tested in Development)

Isotype: Mouse IgG1, κ

Application: Flow cytometry (Routinely Tested)

Vol. Per Test: 20 µl

Workshop Number: IV B98

Entrez Gene ID: 1380

RRID: AB_395816

Storage Buffer: Aqueous buffered solution containing BSA and ≤0.09% sodium azide.

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).
An isotype control should be used at the same concentration as the antibody of interest.
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.
Source of all serum proteins is from USDA inspected abattoirs located in the United States.

Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.

Antibody Details

B-ly4

The B-ly4 monoclonal antibody specifically binds to CD21, a 145 kDa glycosylated type I integral membrane protein. CD21 is a receptor for the C3d complement fragment and for Epstein-Barr virus (EBV). CD21 is expressed on mature B cells, follicular dendritic cells, and some epithelial cells. It is also weakly expressed on the subset of mature T cells and thymocytes. CD21 plays a role in B-cell activation and proliferation. It may also play a role in modulating the function of T cells in the immune response to infections by lymphotropic viruses. Recently, CD21 was found to be part of a large complex containing CD19, CD81, and possibly other molecules.

This clone also cross-reacts with a major subset of, but not all, peripheral blood CD20+ lymphocytes of baboon, and both rhesus and cynomolgus macaque monkeys. A subset of CD3+ cells is also CD21+.

Format Details

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.

Format: PE

Excitation Source: Yellow-Green 488 nm, 532 nm, 561 nm
