ABTS (2,2'-Azinodi 3-Ethyl Benzthiazoline Sulfonic)

2,2'-Azinodi(3-Ethyl Benzthiazoline Sulfonic Acid) (ABTS) is a commonly used chromogen for the detection of Horseradish peroxidase in enzyme immunoassays (ELISA). This single component, produces a soluble blue-green reaction product that is measured at 405 nm. This product requires no mixing prior to use, and has a shelf life of 18 months when stored at 4 - 8° centigrade.

TMB Soluble Reagent (Aqueous)

TMB - This aqueous non-hazardous liquid substrate for peroxidase consists of Tetramethylbenzidine (TMB) plus dilute hydrogen peroxide in a single-reagent stabilized form. The reagent has been specifically formulated for measuring peroxidase in ELISA systems which is stable for long-term storage providing sensitivity greater than OPD. This reagent is available as a single component, ready-to-use reagent. When used in conjunction with our proprietary TMB Stop Buffer (TSB), the resulting color product will not fade or darken for several hours. Our TMB products have been in production for over ten years and have built a reputation for robust performance, unparalleled stability and next to zero lot-to-lot variation. Each TMB formulation can be specifically engineered to meet the needs of your specific assay. Inquire about custom vialing, labeling, kit assembly and drop shipping.
