Product Specifications

Immunogen

Purified H-2Kb and H-2Db MHC-I molecules

Reactivity Notes

Predicted cross-reactivities: Sheep, Rat, Human, Guinea Pig, Hamster, Bovine, Porcine

Please note that this antibody is reactive to Mouse and derived from the same host, Mouse. Additional Mouse on Mouse blocking steps may be required for IHC and ICC experiments. Please contact Technical Support for more information.

Specificity

NB100-65938 recognizes a monomorphic epitope on the mouse MHC class I antigen. The epitope recognized by clone 2G5 is conformation dependent and is reported to be phylogenetically conserved. Reactivity has been observed with some canine samples suggesting that this antibody may recognize a polymorphic epitope of canine MHC class 1.

Clonality

Monoclonal

Host

Mouse

Isotype

IgG2B

Background: MHC Class I

The antigenic agglomerate major histocompatibility complex (MHC) class I molecules present antigenic peptides to CD8-positive T cells. It is now recognized that the products of the MHC genes are antigen-presenting molecules (APM) designed for the presentation of antigen fragments (peptides) to the T-cell receptor, thus participating in the immune response (1). Recently shown is a mechanism of antigen acquisition for cross-presentation that couples the antigen presentation system of two adjacent cells and is lost in most tumours: gap-junction-mediated intercellular peptide coupling for presentation by bystander MHC class I molecules and transfer to professional antigen presenting cells for cross-priming (2). The mammalian vomeronasal organ detects social information about gender, status, and individuality. It has been shown that small peptides that serve as ligands for major histocompatibility complex (MHC) class I molecules function also as sensory stimuli for a subset of vomeronasal sensory neurons located in the basal Gao- and V2R receptor-expressing zone of the vomeronasal epithelium (3).
