Descrizione

Descrizione generale

Peroxidase substrate that is soluble, safe, convenient and has good overall performance in ELISA. ABTS^™ Chromophore develops intense blue-green color that can be measured at 405 nm to 410 nm. May be used for both kinetic and endpoint reactions.

Single component peroxidase substrate which is soluble, safe, convenient and has good overall performance for ELISA. In the presence of horseradish peroxidase (HRP) and hydrogen peroxide, ABTS is oxidized to an intense blue-green, water-soluble product. This product is a radical cation having an absorption maximum at 416 nm. Typically, product formation is measured spectrophotometrically at 405 nm, allowing a quantitative analysis of HRP-based systems. The color formation as a function of time may be monitored, or the reaction may be stopped by the addition of acid; since the acid does not alter the absorbance at 405 nm, one may perform both kinetic and endpoint measurements at the same wavelength.

Attenzione

Toxicity: Irritant (B)

Stato fisico

Contains optimal concentrations of ABTS and H₂O₂ in a citrate buffer (pH 4.0) with proprietary stabilizers.

Ricostituzione

ABTS^™ solution should be stored at 4°C, but must be warmed to room temperature before use. The solution should be protected from exposure to direct sunlight, and should be discarded if it becomes bright yellow or turbid.
