BV421 Rat Anti-Mouse I-A/I-E
BV421 Rat Anti-Mouse I-A/I-E
Multicolor flow cytometric analysis of I-A/I-E MHC class II alloantigen expression on splenocytes from positive and negative mouse strains (left and center panels). Mouse spleen cells from either M5/114-negative SJL (Left Panel) or M5/114-positive BALB/c (Center Panel) mice were stained with BD Horizon™ BV421 Rat Anti-Mouse I-A/I-E (Cat. No. 562564), APC Anti-Mouse CD45R/B220 (Cat. No. 553092/561880) and APC Anti-Mouse CD11b (Cat. No. 553312/561690) antibodies. Two-color flow cytometric dot plots showing the expression of I-A/I-E MHC class II alloantigens versus CD45R/B220 and CD11b were derived from gated events with the forward and side light-scatter characteristics of viable splenocytes. The M5/114 monoclonal antibody detects I-Ad and I-Ed MHC class II alloantigens that are expressed on both B cells and macrophages. Flow cytometry was performed using a BD™ LSR II Flow Cytometer System. Immunohistofluorescent analysis of I-A/I-E expression by cells within C57BL/6 mouse spleen (right panel). A mouse spleen cryosection (5 µm) was fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655), blocked with 5% goat serum and 1% BSA diluted in 1x PBS, and stained with BD Horizon™ BV421 Rat Anti-Mouse I-A/I-E antibody (Cat. No. 562564, pseudo-colored green) and Alexa Fluor® 647 Rat-anti-Mouse CD19 (Cat. No. 557684, pseudo-colored blue). Images were captured on a standard epifluorescence microscope. Original magnification, 20x.

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 BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant™ dyes are used in a multicolor flow cytometry panel.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  4. 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.

M5/114.15.2

The M5/114.15.2 monoclonal antibody recognizes a polymorphic determinant shared by the I-A[b], I-A[d], I-A[q], I-E[d], and I-E[k] (but not I-A[f], I-A[k], or I-A[s]) MHC class II alloantigens that can be expressed by B cells, dendritic cells, monocytes, macrophages and activated T cells. It also reacts with cells from mice of the H-2[p] and H-2[r] haplotypes, and it is non-reactive with cells from NOD (H-2[g7]) mice. Flow cytometric analysis indicates that the M5/114.15.2 and 2G9 monoclonal antibodies have comparable reactivity on cells from mice with I-A[b], I-A[d], I-A[g7], I-A[q], I-E[d], and I-E[k] alloantigens.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
