Abstract:
As result of the First International Swine CD Workshop, four monoclonal antibodies (mAb) (#002, 054, 118, and 127) clustered closely to the internal standard anti-porcine CD4 mAb, 74-12-4. To further characterize the relationship between these mAb, they were used in flow cytometry to inhibit binding of 74-12-4 to porcine lymphocytes. mAb #002 (74-12-4) and #054 (PT90) completely inhibited, while mAb #127 (10.2H2) and #118 (b38c6) partially inhibited (57% and 77% respectively), the binding of 74-12-4. Furthermore, none of the mAbs bound to a 74-12-4 negative strain of pigs. We conclude that the four mAb bind to the same, or a closely related, epitope on porcine lymphocytes.
