Abstract

Aim. The study of the effect of the erythropoietin coating procedure on sensitivity using the same secondary detection methods to quantify anti-EPO IgG positive animal sera. Materials and methods. Sera from experimental animals - rabbits and guinea pigs - after rhEPO injection were used. The methods includes directly coated ELISA and two types of immunochemical immobilization: capturing biotinylated rhEPO on streptavidin coated microtiier plates and capturing rhEPO via a specific antibody Results. Immunochemical rhEPO immobilization results in a sensitivity from 2 to 10 of magnitude higher than direct coating of rhEPO. Conclusion. Our findings show that the method of rhEPO immobilization to microtiter plates is a critical determinant for the sensitivity of ELISA used for measuring anti-EPO antibodies. Assays in which rhEPO was captured via a specific mAb, or in which biotinylated rhEPO was captured via streptavidin, are preferred to detect serum antibodies to native structural state.
