FITC Mouse Anti-Human CD23

BD Pharmingen™ FITC Mouse Anti-Human CD23

Name: FITC Mouse Anti-Human CD23
Brand: FITC Mouse Anti-Human CD23
SKU: 561146

Clone M-L233 (RUO)

Flow cytometric analysis of CD23 expression on human peripheral blood lymphocytes. Whole blood was stained with either FITC Mouse Anti-Human CD23 antibody (Cat. No. 561146; Left Panel) or with a FITC Mouse IgG1, κ Isotype Control (Cat. No. 555748; Right Panel) and Alexa Fluor® 700 Mouse anti-Human CD19 (Cat. No. 557921). The erythrocytes were lysed with BD PharmLyse™ Lysing Buffer (Cat. No. 555899). The two-color flow cytometric dot plots were derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometry was performed using a BD™ LSR II Flow Cytometer System.

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

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.
Source of all serum proteins is from USDA inspected abattoirs located in the United States.
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.

Antibody Details

M-L233

The M-L233 antibody specifically binds to human CD23, the low affinity receptor for human IgE (FcεRII). CD23 is a type II membrane glycoprotein that is expressed by B cells, monocytes, macrophages, eosinophils, platelets and dendritic cells. CD23 mediates IgE-dependent cytotoxicity and phagocytosis by macrophages and eosinophils. Soluble CD23 (sCD23) can be released by CD23-positive cells as a result of proteolytic cleavage of membrane CD23. Larger fragments of sCD23 (e.g., 25-37 kDa) retain their IgE-binding capacity whereas smaller fragments (ie, ≤ 12 kDa) do not. Soluble CD23 may have immunoregulatory effects on the growth and differentiation of B cells and other cell types.

Format Details

FITC

Fluorescein (FITC) is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 518-nm. FITC is designed to be excited by the Blue laser (488-nm) and detected using an optical filter centered near 520 nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Format: FITC

Excitation Source: Blue 488 nm

Excitation Max: 494 nm

Emission Max: 518 nm
