Two competitive enzyme immunoassays for the detection of IgG class antibodies to hepatitis a antigen

Two competitive enzyme immunoassays (EIA) techniques were developed: in the first (COMP-1), test sera were added together with HAV antigen on anti-HAV IgG-coated wells followed by an anti-HA VHRP conjugate; in the second (COMP-2), test sera and anti-HA VHRP conjugate competed for HAV epitopes previo...

description Two competitive enzyme immunoassays (EIA) techniques were developed: in the first (COMP-1), test sera were added together with HAV antigen on anti-HAV IgG-coated wells followed by an anti-HA VHRP conjugate; in the second (COMP-2), test sera and anti-HA VHRP conjugate competed for HAV epitopes previously adsorbed to anti-HA V IgG-coated wells. Both procedures used tetramethylbenzidine (TMB) as a substrate. Both competitive tests were shown to be reproducible and suitable for routine diagnosis and research purposes.<br>Foram desenvolvidos dois ensaios imunoenzimáticos (EIA) competitivos: no primeiro (COMP-1) colocou-se numa placa sensibilizada com anti-HAVIgG as amostras teste juntamente como antígeno HA Vea seguir o conjugado anti-HA VHRP; no segundo (COMP-2), as amostras teste e o conjugado anti-HAV HRP competem pelos epitopos do antígeno HAV previamente absorvido na placa sensibilizada do anti-HAV IgG.
