ELISA Reagents and Buffers
TMB (3,3´,5,5´- tetramethylbenzidine) is a substrate for horseradish peroxidase (HRP). Our mono-component, liquid TMB solutions combine TMB, substrate buffer and hydrogen peroxide for a safe, ready-to-use, one step, chromogen system. The products do not contain harmful solvents. Recommended for ELISA procedures, liquid TMB yields a soluble blue end product read at 655 nm. The TMB reaction may be stopped with 0.2 M H2SO4 resu…
This new type of TMB with a red indicator combines all the important qualities of TMB ONE, eliminating possible mistakes during pipetting. Further the red colour may be 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 solutionand will neither affect the sensitivity nor the stability of the substrate. Stability…
The TMB PLUS has a higher activity level, resulting in a higher sensitivity and a reduced incubation time than found using the TMB ONE. TMB is a substrate for HRP. The mono-component, liquid TMB solution combines TMB, substrate buffer and hydrogen peroxide for a safe, ready-to-use, one step, chromogen system.The product does not contain harmful solvents. Recommended for ELISA procedures, liquid TMB yields a soluble blue end pr…

10 OD to 50 OD concentrated nanoparticles that have been optimized for rapid assays without the traditional boiling and centrifugation steps. The BioAssay Works gold sol production process is unique, by eliminating the boiling step, and because of the concentrated gold, you do not have to dilute the sols prior to conjugation, nor do they have to be centrifuged to remove free antibody. The elimination of these two steps alone i…
The Au/Ag particles have increased advantages in light or laser applications, when taking light scattering measurements. The BioAssay Works silver/gold nanoparticles and conjugates production process is unique, by eliminating the boiling step, and because of the concentrated gold, you do not have to dilute the sols prior to conjugation, nor do they have to be centrifuged to remove free antibody. The elimination of these two s…
New pNPP ONE Substrate – The pNPP (p-NitroPhenyl Phosphate) liquid, ready-to-use substrate is a highly active and stable formulation utilized for measuring AP- (Alkaline Phosphatase) probe activity. The solution is a solvent free buffer solution containing stabilized pNPP using sodium azide as preservative. In kinetic assays p-nitrophenol appears yellow and is measured at 405 /650 nm. If stopped reactions are preferred, add…
