TMB BlueSTOP Solution is formulated to stop color development in microwell assays and maintain the blue color of TMB.  Unlike traditional acid-based TMB stopping solutions, the O.D. value of TMB does not change upon addition of TMB BlueSTOP. The stopped substrate is stable for an extended period and can be read at 650 nm.

TMB BlueSTOP is ideal for use with SeraCare's KPL microwell peroxidase substrates, SureBlue and SureBlue Reserve 1-Component TMB, and TMB 2-Component Microwell Peroxidase Substrate.  The reagent is supplied as a convenient, ready-to-use solution that is stable for a minimum of one year.

Product Highlights:

  • A single 650-nm filter can be used to read TMB before and after stopping.
  • Enables monitoring and control of color development in microwells
  • Stopped reactions are stable for at least 2 hours


  • Application: ELISA
  • Measurement: 650 nm
  • Stability: 2 years from date of receipt
