[Monoclonal antibodies to insulin influencing its biological activity].
Somatic hybridization was employed for obtaining 335 hybridomas producing monoclonal antibodies to insulin. Twelve hybridomas were cloned by a method of maximum dilutions, and specific immunoglobulins, secreted by them, were characterized by solid phase immunoenzyme assay. Monoclonal antibodies possessed different activity with relation to human, porcine and cattle insulins, indicating their specificity to different epitopes on the insulin molecule. Antibodies of IN-2 and IN-3 clones were capable of inhibiting insulin biological activity in vivo. In experiments on rabbits antibodies of IN-2 clone decreased a 3-fold insulin hypoglycemic action, and antibodies of IN-3 clone caused an increase in the life span of mice after administration of insulin at high doses to them.
