As a universal and extensively adopted technique, enzyme-linked immunosorbent assay (ELISA) can be used to detect and quantify small molecules in many applications both clinical and analytical. However, generally, students experiment mechanically using commercial ELISA kits according to the instructions and eventually produce a standard curve to calculate the concentration of the sample to be measured, cannot understand the critical factors and process of method establishment. This study systematically introduced undergraduates to using the pathogen-specific antigen and establishing an indirect ELISA method to detect the diagnostic target pathogen "Burkholderia pseudomallei." This course aimed to develop the experimental skills of the students and improve their scientific research knowledge, which fully embody the organic combination of scientific research and teaching. Students independently selected the diagnostic antigen target of interest, obtained the antigen proteins using genetic engineering techniques, and established an ELISA method through a series of conditional optimization experiments. In addition, typical student-generated data, experimental methods, and a student feedback interpretation are presented in this study. Overall, the students were able to combine abstract knowledge with practice and understand the principles and applications of antigen--antibody interactions, thus enabling them to gain practical experience in molecular biology techniques, and learn how to use this principle to establish an ELISA method for detecting infectious diseases.
