title: In vitro synthesis of anti-mycobacterial antibodies in biopsies from skin lesions of leprosy patients.
abstract: To demonstrate local synthesis of anti-Mycobacterium leprae antibodies, biopsies from skin lesions of leprosy patients were cultured in vitro in a medium containing 14C-labeled lysine and isoleucine, and the culture fluids were analyzed by crossed immunoelectrophoresis with intermediate gel and autoradiography. The results show that anti-M. leprae antibodies were synthesized in vitro in the biopsies from the skin lesions of leprosy patients and that the specificity of the locally produced antibodies varied from patient to patient.
