MHC Class II Antibody (P7/7) - Chimeric - Azide and BSA Free

Immunocytochemistry/Immunofluorescence: MHC Class II Antibody (P7/7) - Chimeric [NBP3-09015] - Immunofluorescence analysis of paraformaldehyde fixed mouse splenocytes immobilized on Shi-fix(TM) cover-slips and stained with the chimeric rabbit IgG version of P7/7 (NBP3-09015) at 10 ug/ml followed by Alexa Fluor(R) 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 NBP3-09015, DAPI, merged channels and an isotype control. The isotype control was stained with anti-Fluorescein antibody followed by Alexa Fluor(R) 488 secondary antibody.

Flow Cytometry: MHC Class II Antibody (P7/7) - Chimeric [NBP3-09015] - Mouse splenocytes were stained with anti-Fluorescein IgG antibody (4-4-20; isotype control, black line) or the rabbit IgG1 version of P7/7 (NBP3-09015, blue line) at a dilution of 1:100 for 1h at RT. After washing, bound antibody was detected using a goat anti-mouse IgG AlexaFluor(R) 488 antibody at a dilution of 1:1000 and cells analyzed using a FACSCanto flow-cytometer.

MHC Class II Antibody (P7/7) - Chimeric - Azide and BSA Free Summary

• Additional Information: Recombinant Monoclonal Antibody
• Immunogen: This antibody was raised by immunising DA rats with PVG.R8 rat spleen cells. Splenocytes from immunised rats were then isolated, and fused to the myeloma line NSO/u to generate stable hybridomas.
• Specificity: This antibody recognises the rat RT1Bu/Du MHC class II antigen, and cross-reacts with haplotypes c, d, l and n. This antibody stains MHC class II molecules in a number of rat strains, including PVG, F334, LEW, and BN. However, this antibody is not reactive with RT1a haplotype rats, including Wistar rats. This antibody also cross-reacts with murine I-A and I-E molecules of all haplotypes tested, including H-2b, d, f and k, so can be used in all mouse strains.
• Isotype: IgG Kappa
• Clonality: Monoclonal
• Host: Rabbit
• Gene: HLA-DMA
• Purity: Protein A purified

Applications/Dilutions

• Dilutions:
  • Flow Cytometry
  • Immunocytochemistry/ Immunofluorescence
  • Immunohistochemistry
  • Immunoprecipitation
• Application Notes: This chimeric rabbit antibody was made using the variable domain sequences of the original Rat IgG2b format, for improved compatibility with existing reagents, assays and techniques.
  
  This antibody reacts with murine MHC class II I-A and I-E molecules, as confirmed by two-dimensional gel electrophoresis of Ia immunoprecipitates from metabolically labelled murine lymphoma cells (Momburg et al, 1986). Cross-blocking studies with anti-Ia beta -chain MAbs indicate that P7/7 binds to the beta -chain of murine Ia (Momburg et al, 1986). This antibody has been used to stain acetone-fixed mouse pancreas sections to study lymphocyte infiltration (Signore et al, 1987; Signore et al, 1989) and ethanol-fixed mouse brain sections (McMenamin et al, 1998). In flow cytometric analysis, this antibody has been employed to identify MHC class II-expressing murine cells (Hayball & Lake, 2004; Heath et al, 1991), and to analyse the surface phenotype of murine N9 microglial cells (Dimayuga et al, 2005). This antibody has been used in immunofluorescence analysis of acetone-fixed thymus sections to identify MHC-II positive and negative medullae (Aschenbrenner et al, 2007).

Background

MHC Class II antigens are heterodimers consisting of one alpha chain(31-34kD) and one beta chain (26-29kD). The family of monoclonal antibodies (ER-TR 3, ER-TR 2, ER-TR 1) detect MHC class II antigens encoded by the murine Ia region of the H-2 complex, corresponding to the human HLA-DR region. MHC Class II antigens are a valuable tool for studying T helper cell interaction with class II positive antigen presenting cells (dendritic cells, B cells, macrophages) and offer new possibilities for studying the development of T helper cells since these antibodies also stain stromal cells in the thymus. MHC Class II antigens are also inducible on a number of other cells (endothelium and epithelial cells) by interferon gamma.
