A panel of 380 commercially available monoclonal antibodies (mAbs) against human CD molecules from various sources was tested during the 8th Human Leukocyte Differentiation Antigen Workshop (HLDA8) for cross-reactivity on canine peripheral blood leukocytes by flow cytometry. In addition, all mAbs were used to label a 50:50 mixture of platelets and erythrocytes of the same dogs. This testing resulted in 51 cross-reacting mAbs. mAbs with specificity for CD9, CD29, CD42a, CD61, and CD41/CD61 showed cross-reactivity with canine platelets in a non-polymorphic and one mAb with the erythrocyte antigen CD235a in a polymorphic reaction pattern. Canine leukocyte-reactive mAbs included those with specificity for CD11a, CD11b, CD14, CD18, CD21, CD22, CD47, CD49d, CD49e, CD56, CD62L, CD91, CD94, and CD172a. In addition, several mAbs resulted in a staining pattern of canine cells which suggest that the canine epitope equivalents have an alternate expression pattern from that expected for humans (CD1a, CD35, CD44, CD45, CD75s, CD81). In summary, this study confirmed the reactivity of previously described cross-reactive mAbs with canine cells and resulted in the characterization of mAbs recognizing so far undetectable canine CD molecules.

Three hundred and seventy six monoclonal antibodies (mAbs) raised against human leukocyte surface antigens were analyzed by flow cytometry for cross reactivities against mink leukocytes. We found 53 mAbs (14%) to cross react. This study defined cross reactions to the following human markers: CD1a, CD9 (4 mAbs), CD10, CD11a (2 mAbs), CD14 (3 mAbs), CD18 (5 mAbs), CD20 (atypical reaction), CD21, CD25 (atypical reaction), CD29 (3 mAbs), CD32, CD41, CD42a, CD44 (4 mAbs), CD45, CD45RO, CD47 (2 mAbs), CD49d (3 mAbs), CD61 (2 mAbs), CD62P, CD66abcd, CD71, CD75s, CD79b (2 mAbs), CD86, CD88, CD104 (atypical reaction), CD172a, CD236R (glycophorin C, (atypical reaction)), Xg(a) carbohydrate antigen, Rhesus antigen and two unspecified PAN-reactive mAbs. In order to characterize the molecular mass of the corresponding cross reacting mink markers, the mAbs were used to immunoprecipitate the surface antigens. Fourteen mAbs out of the 53 mAbs reactive with mink leukocytes gave reproducible IP findings. The masses of the precipitated antigens were generally in good agreement with those of the homologous human markers. We also performed immunohistochemical staining analyses on formalin fixed, paraffin embedded mink tissue from lymph node and spleen, and found 7 out of 22 mAbs to give a positive signal. Generally, the immunohistological analyses resulted in expected staining patterns.
