TMB PLUS2 Prestained
Prestained TMB PLUS2™, 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 PLUS2™, 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 40% higher activity level than Prestained TMB ONE™, resulting in a higher sensitivity and a reduced incubation time compared to TMB ONE™
- Cost effective
- Improved version of the TMB PLUS™
- Negligible batch-to-batch variations
- Free of harmful organic solvents
- Development time: 5-30 minutes
- Stop solution: 0.2 M H2SO4
- At least 4 years at 2-8° C
