Objective To develop a sensitive and stable substrate for enzyme‐linked immunosorbent assay(ELISA)and carry out methodology evaluation tests on it .Methods A kind of substrate with tetramethyl benzidine and urea peroxide as its main compo‐nents were made up ,its sensitivity ,precision and storage stability were evaluated and compared with other three kinds of substrate . Results This substrate was more sensitive than two of the three commercial substrates .The variable coefficient of precision test was 3 .5% .The optical densities(OD) of the new substrate after stored one day ,seven days ,one month ,six months ,twelve months in 4 ℃ environment were 2 .268 、2 .403 、2 .358 、2 .278 、2 .330 respectively ,the standard deviation was 0 .056 185 ,the variable coeffi‐cient was 2 .4% .Conclusion The substrate proposed in this paper displays good sensitivity ,precision and stability .The preparation method is simple ,reproducible .This substrate not only satisfies the requirements of laboratory research ,but also meets with the de‐mands for commercial kit development due to its function as an important component of test kits .It is an economical and effective choice for both laboratories and research transformation .
