Revision17-April-2008 RFH
Synonyms2,2ʹ-Azino-bis(3-ethylbenzthiazoline-6-sulfonic Acid)
DescriptionSingle 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.
FormClear to very pale yellow solution
FormulationContains optimal concentrations of ABTS and H₂O₂ in a citrate buffer (pH 4.0) with proprietary stabilizers.
Recommended reaction conditionsSuggested procedure for use of ABTS in HRP-based ELISAs: 1. Complete all required incubations with antibodies and HRP-labeled probes. 2. Wash plate wells at least 4 times with phosphate-buffered saline (PBS) or Tris-buffered saline (TBS), containing 0.1% Tween®-20 detergent. 3. After the final wash, shake and blot all residual buffer from the wells. 4. Add 100 µl of ABTS Solution to each well and incubate at room temperature for up to 30 min. (If a kinetic study is desired, readings at 405 nm may be taken at intermediate intervals.) Note: Optimal incubation times may vary depending on the amount of HRP present. If color develops too quickly, zero order kinetics will not prevail. Dilution of the probe, antibody, or HRP-labeled reagent may be required. 5. Add 100 µl of stop solution, mix well, and read absorbance at 405 nm. [A 0.625 M oxalic acid solution is recommended as a stopping solution, as the colored product is most stable with this reagent (at least 1 h). Other acids may be employed (0.625 M oxalic acid > 0.5 M H2SO4 > 0.5 M HCl). 1% SDS may also be used as a stopping solution, provided that it is pure and clear (impure or turbid SDS solutions may interfere with absorbance readings).] Note: Variations in time, reagent volumes, and temperature may require further standardization by the user.
