(a) Detection of CFP10-ESAT6 using conventional ELISA method with illustration of binding antibody-antigen complex with labelled detection antibody in sandwich form. Negative controls (without antigen) show that no colour appears in well 3, whereas wells containing antigen show blue coloured signal. (b) Detection of CFP10-ESAT6 using our developed LFIA platform with illustration of binding antibody-antigen complex in sandwich form. Two coloured lines indicate the presence of antigen, while one coloured line indicates no antigen detection.
