Recombinant Antibody
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.
Alternative Names
P7.7; I-A; Ia; I-E; MHC-II; MHC Class II
UniProt
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.
Application Notes
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 β-chain MAbs indicate that P7/7 binds to the β-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).
