Product Summary for MHC Class I Antibody (R1-21.2) - Chimeric - Azide and BSA Free


This antibody was raised by immunising Lewis 1F rats with mouse CH-1 lymphoma cells. Spleen cells from immunised rats were fused with X-63Ag8-653 myeloma cells to generate hybridomas.


This antibody is specific for murine MHC class I, and binds to polymorphic H-2 determinants expressed on most haplotypes. This antibody is, therefore, able to bind all H-2 class I molecules, independent of the allele. This antibody inhibits the binding of most mouse anti-H-2 antibodies to H-2k cells.

Scientific Data Images for MHC Class I Antibody (R1-21.2) - Chimeric - Azide and BSA Free

Western Blot: MHC Class I Antibody (R1-21.2) - Chimeric [NBP3-09017] - Mouse thymus tissue lysate (35ug protein in RIPA buffer) was resolved on a SDS PAGE gel and blots were probed with NBP3-09017 at 1 ug/ml before detection using an anti-rabbit secondary antibody. A primary incubation of 1h was used and protein was detected by chemiluminescence.
Immunocytochemistry/Immunofluorescence: MHC Class I Antibody (R1-21.2) - Chimeric [NBP3-09017] - Immunofluorescence analysis of paraformaldehyde fixed mouse splenocytes immobilized and stained with NBP3-09017 at 10 ug/ml followed by Alexa Fluor 488 secondary antibody (2 ug/ml), showing membrane staining in a subset of cells. The nuclear stain is DAPI (blue). Panels show from left-right, top-bottom NBP3-09017, DAPI, merged channels and an isotype control. The isotype control was stained with anti-Fluorescein antibody (NBP2-52638) followed by Alexa Fluor 488 secondary antibody.

Application Notes
This chimeric rabbit antibody was made using the variable domain sequences of the original format, for improved compatibility with existing reagents, assays and techniques.

This antibody binds murine H-2 MHC class I molecules, and has been used in both structural and biochemical studies. It has been employed to assess MHC class I expression in frozen, acetone-fixed mouse brain sections by immunohistochemistry (Miralves et al, 2007), and to stain paraffin-embedded sections of mouse liver for H-2Kb expression (Limmer et al, 2005). It has also been used to precipitate mouse H-2Kk and H-2Dk class I molecules from detergent lysates of Ltk3.3/1 cells (Rada et al, 1990), and to stain H-2Kb and H-2Kk-expressing cells in FACS analysis (Bendelac, 1995). Cellular radioimmune assays have been used to confirm the binding of this antibody to spleen cells, and assess its strain specificity (Koch et al, 1983).
Please Note: Optimal dilutions of this antibody should be experimentally determined.

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).
