Please suggest any paper which gives the ABTS radical conc. Used in peroxidase assay in ELISA . The product from MERCK doesnt mention the conc. In the specification
Normally an 1mg/ml in perborate buffer. Check the Sigma-Aldrich catalogue number # 10102946001 . They have a recipe for the ABTS working solution on website. Just a note - TMB is much more sensitive than ABTS.
