Abstract
Twenty-six monoclonal antibodies (mAbs), assigned to the CD44/CD45 section of the First International Swine CD Workshop, were compared for their reactivity against a selected group of target cells by one- and two-color flow cytometric analysis. Based on staining and reactivity patterns the 26 mAbs were assigned to six groups, group F1 mAbs were designated CD44 mAbs; and groups F2 and F3 as CD45 mAbs. With the information available, a CD designation could not be given to the mAbs in groups F4, F5 or F6 consisting of four, three and four mAbs each, respectively. The reactivity of all six mAbs in group F1 (MAC35, 25–32, PORC24A, H22A, BAG40A, and BAT31A) was blocked by soluble porcine CD44. One mAb in this group (MAC325) reacted with a cell surface protein with a molecular weight of 80 kDa and was designated as CD44; the other five mAbs were designated as wCD44 because no molecular weight was known. Blocking experiments utilizing a cross reactive anti-human CD44 (mAb Z062) allowed the definition of the wCD44a epitope recognized by mAbs PORC24A and H22A. The group F2 mAbs (74-9-3; MAC323; K252.1E4; and 2A5) were designated as CD45 based on their broad reactivity pattern with lymphoid and myeloid cells and their ability to immunoprecipitate three polypeptides with an apparent molecular weight of 226, 210 and 190 kDa. The F3 mAbs (MAC327; MAC326; 3a56 and −a2) were designated as CD45R based on their restricted reactivity against lymphoid and myeloid target cells, and their ability to immunoprecipitate either two polypeptides with an apparent molecular weight of 226 and 210 kDa (mAbs MAC327 and MAC326) or a single polypeptide with an apparent molecular weight of 210 kDa (mAbs −a2 and 3a56). Sequential immunoprecipitation analyses confirmed the relatedness of the F2 and F3 group mAbs. The work conducted for this first workshop led to the definition of six mAbs specific for CD44, four mAbs specific for CD45, and four mAbs specific for CD45R which should prove to be very valuable reagents for the study of the porcine immune system.
