TMB X-tra Prestained

Prestained TMB X-tra, ready-to-use substrate for colorimetric detection in ELISAs based on Horseradish Peroxidase labeled antibodies.

  • This patented type of TMB with a red indicator combines all the important qualities of TMB X-tra™, eliminating possible mistakes during pipetting. The red color is also useful in automatic analyzers, giving the warning “Reagent low” when it is time for filling up the substrate. The red indicator disappears after addition of the stopping solution and will neither affect the sensitivity nor the stability of the substrate.
  • Ready-to-use, Mono-component, one-step chromogenic substrate containing 3,3′,5,5′-tetramethylbenzidine, substrate buffer and hydrogen peroxide
  • approximately 60% higher activity level than Prestained TMB ONE™, resulting in a higher sensitivity and a reduced incubation time for a fast assay reaction
  • excellent resistance to raised temperatures
  • Negligible batch-to-batch variations

Properties

  • Free of harmful organic solvents
