The ELISA has a specificity of over 99%. It is so specific that we only need to use clean pipettes, microtiter wells, and reagents. They do not need to be sterile. What accounts for this very high specificity?
A) The presence of enzymes in the reagents
B) The presence of antibodies in the microtiter wells
C) The unique binding properties of the antigen-antibody interaction
D) The use of fluorescence detection
