Used to measure the concentration and activity of human α-enolase (ENO1) in biological samples such as serum, plasma, cell lysates, and tissue homogenates. This ELISA kit is particularly useful in research settings focused on cancer, where ENO1 is overexpressed in various tumors including lung, breast, and pancreatic cancers. It enables researchers to study the role of ENO1 in tumor metabolism, cell proliferation, and immune modulation. The kit is also applied in autoimmune disease research, as ENO1 can act as an autoantigen. Its high sensitivity and specificity make it suitable for monitoring disease progression and evaluating therapeutic responses in experimental models.
