Elisa assays are prone to two common types of standard errors, which must be watched out for and controlled against these are edge effect and hook effect an edge effect is the result of inconsistencies in the production of elisa multiwell plates or when assay conditions, such as stacking plates, cause the outer wells to behave differently. The difference between direct and indirect elisa is that indirect elisa requires the addition of a secondary antibody, while direct elisa only uses a primary antibody indirect elisa is considered to be more sensitive when detecting substances, but direct elisa is a quicker, cheaper process that . When developing any new elisa, it is important to test several different blockers for the highest signal: noise ratio in the assay many factors can influence nonspecific binding, including various protein: protein interactions unique to the samples and antibodies involved.
