Characterization of a Monoclonal Antibody Specific for the Parasite Surface Antigen-2 of Leishmania major
The Leishmania major Parasite surface Antigen-2 (PSA-2) is a family of glycoinositol phospholipids anchored glycoprotoins expressed in both promastigotes and amastigotes. Promastigote PSA-2 comprises three polypeptides with approximate molecular weight of 96, 80 and 50 kDa. Amastigote express a dist...

The Leishmania major Parasite surface Antigen-2 (PSA-2) is a family of glycoinositol phospholipids anchored
glycoprotoins expressed in both promastigotes and amastigotes. Promastigote PSA-2 comprises three polypeptides with
approximate molecular weight of 96, 80 and 50 kDa. Amastigote express a distinct but closely PSA-2 polypeptide with
molecular weight of 50 kDa. In this study fusion of SP2/0 myeloma cells with immunized mice spleenocytes infected with
promastigotes of L. major intraperitoneally resulted to a clone of hybridoma producing a specific antibody that only reacts
with L. major parasite surface antigen (PSA-2). This mAb showed no crossreactivity with either other Leishmania species
including L. tropica, L. donovani and L. infantum or recombinant gp63. Western blot analysis of culture supernatant
revealed multiple bands with molecular weight of 50, 58, 80 and 96 kDa only in L. major. |
