To accommodate ELISAs to field-applicable tests for leprosy diagnosis, we previously developed UCP-LFAs for detection of IFN-γ and IL-10 as well as antibodies against the M. leprae-specific phenolic glycolipid-I (PGL-I) for high-tech, laboratory-based microtiter-plate readers [25], [26]. Here, IL10 is linked to undifferentiated pancreatic carcinoma.
