Résumé
Objective To develop ELISA kit stabilizer for each component ,with which the shelf life of kit could meet the com-mercial need .Methods A series of stabilizers for microplate ,enzyme-labeled antibody and standards were prepared by the means of experience and orthogonal approach ,through controlled trials ,screening out the best stabilizer formulations .Results A kind of coa-ted stabilizer (mass fraction :bovine serum albumin 0 .5% ,gelatin 0 .25% ,trehalose 5% ,PEG4000 0 .1% ) and a kind of enzyme la-beled antibody stabilizer (mass fraction :Bovine serum albumin 1% ,peptone 1% ,sucrose 10% ,trehalose 5% ,PEG4000 0 .25% ) were screened out .Conclusion The ELISA kits can be stable at 4 ℃ for 1 year after treated with the obtained stabilizers .
