Brand: PE Mouse Anti-Human IgA2
SKU: 571777

Clone A9604D2 (also known as DLDD2) (RUO)

Multicolor flow cytometric analysis of IgA2 expression on viable Human peripheral blood lymphocytes. Human peripheral blood mononuclear cells (PBMC) were washed and cultured in complete tissue culture medium overnight to minimize nonspecific immunofluorescent staining. The cells were harvested and stained with APC Mouse anti-Human CD19 antibody (Cat. No. 555415) and with either PE Mouse IgG1, κ Isotype Control (Cat. No. 349043; Left Plot) or BD Pharmingen™ PE Mouse Anti-Human IgA2 antibody (Cat. No. 571776/571777; Right Plot). DAPI Solution (Cat. No. 564907) was added to cells right before analysis. The bivariate pseudocolor density plot showing the correlated expression of cell surface IgA2 (or Ig isotype control staining) versus CD19 was derived from gated events with the forward and side light-scatter characteristics of viable (DAPI-negative) lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

Preparation And Storage

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. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

Source of all serum proteins is from USDA inspected abattoirs located in the United States.
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.
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).
For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
An isotype control should be used at the same concentration as the antibody of interest.

Antibody Details

A9604D2

The A9604D2 monoclonal antibody specifically recognizes the Fc region of the human Immunoglobulin A (IgA) subclass known as IgA2. IgA2 is comprised of two identical heavy chains encoded by IGHA2, and two light chains, either Igκ or Igλ, that are linked together by disulfide bonds. The A9604D2 antibody does not crossreact with other human immunoglobulin heavy chain (IgH) subclasses, including the IgA1 subclass. IgA2 is expressed by plasmablasts, plasma cells, and memory B cells as well as by some myeloma or plasmacytoma cells. IgA2 is expressed in either a transmembrane form that serves as an antigen-specific B cell surface receptor or in a soluble secreted form. Monomeric and dimeric forms of IgA2 are found in the serum although at lower levels than IgA1. Multimeric forms of secretory IgA2 connected by a J-chain and secretory component are typically found in higher levels than IgA1 in bodily secretions. Secretory IgA2 is transported across epithelial cells and into the lumen of mucosal tissues including the gastrointestinal and respiratory tracts and is found in human breast milk. IgA2 functions in the agglutination of microbes and can block their adherence to or infection of human cells. It can also bind to CD89 (FcαRI) expressed on neutrophils, monocytes, macrophages, and eosinophils to trigger a variety of immune responses including phagocytosis, antibody-dependent cell-mediated cytotoxicity, and the release of inflammatory cytokines and mediators such as in the response to microbes.

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.
