Mouse anti Rat MHC Class II RT1Bu/L antibody, clone OX-3 (MCA45R) used to demonstrate MHC Class II staining on rat brain by immunohistochemistry on cryosections.
Image caption:
Increased immunoreactivity for MHC-II in the CC after focal striatal ischemia. Photomicrographs represent control animal injected with sterile saline (A,B) or ischemic animals injected with ET-1 at 3 (C,D); 7 (E,F); 14 (G,H); and 30 (I,J) PLDs. Maximum MHC-II immunoreactivity was present at 7 days (E,F), which has been confirmed by quantitative analysis (K). The results of quantitative analysis (K) are expressed as mean ± standard error of the mean (SEM). One-way ANOVA with Tukey’s post-hoc test (p <0.05). Similar overwritten letters did not show significant statistical differences. Left-sided photomicrographs in lower magnification with a scale bar of 20 μm, and right-sided ones, with higher magnification with a scale bar of 100 μm.

Mouse anti Rat MHC Class II RT1Bu/L antibody, clone OX-3 recognizes a polymorphic determinant of the rat RT1B MHC class II antigen, reacting with haplotypes u and l. The literature reports reactivity with Lewis, Wistar and AO strain rats but not BN, DA or PVG/c strains. This antibody is useful for distinguishing RT1B positive cells from different rat strains, e.g. for recognising cells of donor origin in bone marrow reconstituted radiation chimaeras.

The major histocompatibility complex (MHC) is a cluster of genes that are important in the immune response to infections. In rats, this complex is referred to as the RT1 region. In mice, this complex is referred to as the H-2 region.

Mouse anti Rat MHC Class II RT1Bu/L antibody, clone OX-3 also cross reacts with mouse strains of the H-2 haplotypes b and s. Analysis of recombinant mouse strains has mapped the OX-3 determinant to the H-2I-A region.

This product is routinely tested in flow cytometry on Lewis rat splenocytes.
