article, and we have added most of the antibodies in this publication to
the database: We have started adding many of the commercially available
antibodies which were derived against these less typical species, so
we have one resource to look for these reagents.  > Analysis of the

213 Monoclonal antibodies (mAbs) raised against leucocyte surface antigens
from human and 11 animal species were analyzed for reactivities against
leucocytes from human and 15 different animal species. We found 77 mAbs
(36%) to cross-react. Altogether, 217 cross reactions were registered out
of 3195 possible combinations (7%). Most of the cross reacting mAbs had
integrin or MHC class II specificities. This study defined cross reactions
on the following markers: CD1a, 1c, 2, 4, 5, 8, 9, 11a, 11b, 14, 18, 20,
21, 23, 29, 31, 41, 43, 44, 45, 45R, 46, 49, 61, 62L, TCR gamma/delta,
BCR, Thy-1, MHC class I and MHC class II, Swine-WC7 and Cattle-WC1. In
order to characterize the molecular weight (MW) of the corresponding
cross reacting antigens, selected mAbs were used to immunoprecipitate
the antigens. The MW's of the analyzed precipitated antigens were in
good agreement with the MWs of the homologous antigens. The followed
strategy was found to be efficient and economical in defining new
