Abstract:
A panel of 377 commercially available monoclonal antibodies (mAbs) specific for a total of 144 CD antigens was submitted to the animal homologue section of the Eighth International Workshop on Human Leukocyte Differentiation Antigens (HLDA8, Adelaide, Australia) for cross-reactivity studies in a range of vertebrate species. Each of the mAbs in this study was screened for positive reactivity with guinea pig splenocytes by flow cytometry. In the first phase of this study 36 of the total 367 mAbs (9.81%) cross-reacted with splenocyte surface molecules. The majority (26 of 36) of these cross-reactive mAbs were analysed further to confirm appropriate cell subset expression by two-color immunofluorescence. Our results indicate that 15 anti-human CD9, CD10, CD14, CD20 (two clones), CD22, CD25, CD29 (two clones), CD32, CD47 (two clones), CD49d, CD49e, and CD86 mAbs exhibit clear cross-reactivity with guinea pig splenocytes. These mAb can potentially be added to the limited repertoire of reagents available for studies in this model system. This data clearly indicates that mouse anti-human CD mAb guinea pig cross-reactions have been defined and that an aim of this HLDA8 section has been fulfilled, i.e., to identify mAbs which recognize conserved, species-independent CD epitopes. These results will contribute to the availability of mAbs and tools in veterinary medicine and immunology.
