Figure 4From: Evaluation of an in silico predicted specific and immunogenic antigen from the OmcB protein for the serodiagnosis of Chlamydia trachomatis infectionsReproducibility of the OmcB Ct ELISA assay. The figure shows OD values, at 450 nm, of the 12 tested sera obtained in two ELISA tests conducted on two different days. Each line indicates the reactivity of one serum on the two days. The differences between the OD values for all sera were less than 20%.Back to article page
