Mouse Anti-CD28 Recombinant Antibody (clone 1C6) (CAT#: PABL-365)

Recombinant Mouse Antibody (1C6) is capable of binding to Canine CD28. This antibody could inhibit MLRs at 20 nanomolar concentrations as effectively as CTLA4-Ig, suggesting that the binding site of the mAb inhibits CD28 interaction with CD80/CD86.

Figure 1 Histopathology of 4 dogs treated with anti-CD28 (1C6) mAb.

The top left panel shows H520 necropsy lung section at 100× magnification demonstrating edema (top arrow), dense lymphocytic infiltrate (middle arrow), and hemorrhage (bottom arrow). The middle left panel shows H520 necropsy lung section at 250× magnification after antimouse peroxidase polymer staining of deparaffinized lung section (arrow points to pulmonary macrophages coated with anti-CD28 mAb). The bottom left panel shows 250× magnification of antirabbit peroxidase polymer control. The top middle panel shows H517 necropsy small intestine section at 100× magnification demonstrating significant hemorrhage on the tips of the villi. The center middle row shows normal small bowel at100× magnification for comparison. The bottom center panel shows H208 necropsy small intestine section at 100× magnification; the arrow points to an enlarged and densely packed Peyer patch. The top right and middle right panel shows H514 necropsy lymph node section at 100× (top) and 250× (middle) magnifications; the arrows point to apoptotic bodies. Slides are stained by hematoxylin and eosin unless otherwise noted.
