Description Monoclonal antibodies were raised against pathogenic promastigotes of Leishmania donovani of Indian origin.
Among these, one was used for immuno-affinity purification of a 78 kDa membrane protein present in both the
amastigote and promastigote forms of the parasite. Results of immunoblot experiments with the anti-78 kDa
antibody revealed that the protein was present only in parasites belonging to the L. donovani complex. The
expression of the protein was observed to be the same during different phases of growth of the promastigotes.
Therefore, the 78 kDa protein is neither stage-specific nor differentially regulated. Surface iodination and
subcellular fractionation of the promastigotes indicated that the protein was localized on the cell surface. The
78 kDa protein was found to inhibit the binding of promastigotes to macrophages significantly, suggesting that
it may play a role in the process of infection. Thus, here we report the purification of a surface protein of
L. donovani of Indian origin, which may play an important role in the process of infection.
