General Notes
Mouse anti Sheep MHC class II Dq DR antibody, clone 49.1 recognizes a polymorphic epitope on ovine MHC class II DQ and DR molecules, constitutively expressed on antigen presenting cells including dendritic cells, B lymphocytes, monocytes, macrophages, activated T lymphocytes and may be induced on a range of other cell types by interferon gamma.The major histocompatibility complex (MHC) is a cluster of genes some of which are important in the immune response to infection. In sheep, this complex is referred to as the ovine leukocyte antigen (OLA) region. There are 2 major types of MHC class IIa molecules encoded by the OLA which are DR and DQ each composed of an alpha and beta chain. Mouse anti Sheep MHC class II Dq DR antibody, clone 49.1 recognizes ovine MHC II transfectants DQ - T28.1, DQ - T26.2 and DR - T31.3 but not DR - T8.1 (Ballingall et al. 1995).
