Regulatory Status Legend
The M1/42 monoclonal antibody (mAb) specifically recognizes intact Histocompatibility-2 Region (H-2) class I antigens (Ags), also known as mouse Major Histocompatibility Complex class I (MHC-I) Ags. This mAb reportedly binds to one or more of the H-2 Ags (H-2K, H-2D, and likely H-2L) that are primarily expressed on most nucleated somatic cells of hematopoietic and nonhematopoietic origin. H-2 class I molecules are comprised of a ~45-50 kDa type I transmembrane heavy chain glycoprotein that is noncovalently linked to ~13 kDa β2-microglobulin (β2-m). The extracellular region of the polymorphic heavy chains is comprised of three globular domains (α1, α2, and α3), followed by a transmembrane region and a cytoplasmic tail. Sequence variations are manifest in regions of the α1 and α2 domains that line the peptide-binding cleft involved in Ag presentation. The M1/42 mAb reportedly binds to H-2 class I Ags from multiple mouse haplotypes including a, b, d, j, k, s, and u. It does not bind to separated H-2 class I heavy chains or β2-m. Cell surface CD8 molecules bind to invariant sites of the H-2 heavy chains and can provide coreceptor signaling for Ag-mediated activation through the T cell receptor. H-2 class I molecules that present self-Ags can lead to self-tolerance of maturing CD8+ T cells due to thymic selection. Alternatively, these molecules can present foreign peptide Ags to mature peripheral CD8+ T cells resulting in cell-mediated immune responses against foreign Ags. H-2 class I Ags also serve as ligands for activating and inhibitory receptors expressed by NK cells and some T cells. The M1/42 antibody is useful for analyzing H-2 class I Ag expression on cells or cell lines. Cells from different experimental systems, eg, stressed cells that have undergone infection or transformation, may express little or no H-2 class I Ag. In contrast, cells undergoing activation or responding to certain factors (eg, interferons) may express upregulated levels of these Ags.
The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50-nm) filter set. BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser.
BV510 is a polymer-based dye that is brighter than BD Horizon V500. Due to similar excitation and emission properties, BD Horizon BV510 and BD Horizon V500 cannot be used simultaneously.

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 BV510 under optimal conditions that minimize unconjugated dye and antibody.
- This antibody was developed for use in flow cytometry.
- The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- 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.

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) are used in the same experiment. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794).
