Introduction: Leishmania parasitic infections are the important causes of health problems in many parts of the world, especially in developing countries. Monoclonal antibodies have been used as valuable tools for the detection, treatment and characterization of the antigenic markers of parasites. This study through applicable techniques aims to produce mAbs against Iranian type of Leishmania( L). infantum. Materials and Methods: Standard strains were cultured and their antigens were used. BALB/c mice were injected with freeze-thawed promastigote twice together with Freund adjuvant. Three days before cell-fusion, the antigen through vein was injected into the mice. Then the mice were killed. After that their spleen lymphocytes were mingled with myeloma SP2/0. In the next step, the isolation of monoclones was performed by limiting dilution method. Results: 16 mAb against promastigote form of L.infantum parasite were obtained ,3 of which showed optical density (OD) more than 1nm, designated as 5D2 FV, 4G5 FV and 5D6 FIV. Then, anti-promastigotes L.infantum mAbs were obtained from these hybrids. These antibodies are effective in the logarithmic phase of the parasite. Conclusion: It seams these antibodies can demonstrate reaction against Iranian strain of promastigotes L. infantum and can be employed in the diagnosis of kalazar disease
