BD Pharmingen™ PE Mouse Anti-Human HLA-DR

Name: PE Mouse Anti-Human HLA-DR
Brand: BD Pharmingen™
SKU: 568230

Clone L243

(RUO)

Multiparameter flow cytometric analysis of HLA-DR expression on human peripheral blood leucocyte populations. Whole blood was stained with either PE Mouse IgG2a, κ Isotype Control (Cat. No. 553457; Left Plot) or PE Mouse Anti-Human HLA-DR antibody (Cat. No. 568230/568231; Right Plot). Erythrocytes were lysed with BD PharmLyse™ Lysing Buffer (Cat. No. 555899). A bivariate pseudocolor density plot showing the correlated expression of HLA-DR (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 Celesta™ Cell Analyzer System and FlowJo™ software.

Product Details

Brand: BD Pharmingen™

Alternative Name: MHC class II antigen; HLA class II histocompatibility antigen

Reactivity: Human (QC Testing)

Isotype: Mouse IgG2a, κ

Immunogen: Human lymphoblastoid B-cell line RPMI 8866

Application: Flow cytometry (Routinely Tested)

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 to the dye under optimum conditions and unconjugated antibody and free dye were removed.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to 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 CompBead to ensure that BD® CompBeads are appropriate for your specific cellular application.

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

L243

The L243 monoclonal antibody specifically binds to HLA-DR, a major histocompatibility complex (MHC) class II antigen. HLA-DR antigens are encoded by genes within the Human Leukocyte Antigen (HLA) Complex located on chromosome 6. HLA-DR is a transmembrane heterodimeric glycoprotein composed of an α chain (36 kDa) and a β subunit (27 kDa) expressed primarily on antigen presenting cells including B cells, dendritic cells, monocytes, macrophages, Langerhans cells, and thymic epithelial cells. HLA-DR is also expressed on activated T cells. This molecule plays a major role in mediating cellular interactions during antigen presentation to CD4-positive T cells.

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
