MHC Class I antibody | VPM19
The major histocompatibility complex (MHC) is a cluster of genes that are important in the immune response to infections. In sheep, this is often referred to as the ovine leukocyte antigen (OLA) region. Ovine MHC Class I functions in the recognition and presentation of foreign antigens to T-cells.
Ovine MHC Class I is a membrane glycoprotein with a molecular weight of approximately 44kDa, expressed on the cell surface of all peripheral blood leucocytes.
Clone VPM19 has been in used in studies on a number of domestic animal diseases, in particular Maedi Visna virus infection, a disease of significant inportance in commercial sheep flocks (Lee et al. 1996, Ryan et. al. 2000 and Wu et. al. 2008). Clone VPM19 has been cited as recognising MHC class I in some other species and has been used in a study of Feline herpes virus infection (Montagnaro et. al. 2009).
