Tmb stop solution recipe
Web1N or 2N HCl can be used as stop solution for TMB instead of 2M H2SO4 Cite 1 Recommendation 8th Feb, 2016 Anne Balloch Murdoch Children's Research Institute We use 2M orthophosphoric acid.... WebIt is customary in most routine ELISA protocols using TMB as the chromogenic substrate to stop the TMB color development process by the addition of some formulation iteration of acidic stopping solution. The intent here is to create a low enough pH environment from addition of the acid stop solution to shut down the HRP redox activity.
