Ready-to-use solution for ELISA.

Supplier: MP Biomedicals

2,2-Azino-bis-(3-ethyl-benzthiazoline-6-sulfonic acid) (ABTS) has been used as a chromogenic substrate for horseradish peroxidase (HRP), both in general activity assays and in ELISA applications. Activity of HRP using ABTS appears about four-fold higher than using pyrogallol. It is mainly used as a substrate in sensitive peroxidase assays.
2,2′-Azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) is a peroxidase substrate suitable for use in ELISA procedures. This substrate produces a soluble end product that is green in color and can be read spectrophotometrically at 405 nm. The reaction may be stopped with 1% sodium dodecyl sulfate (SDS). Recommended for ELISA (microwell) procedures, not recommended for membrane applications.

2,2'-Azino-bis-(3-ethylbenzthiazoline-6-sulfonic Acid) Solution is oxidized to a radical action showing absorption maxima at 820 nm, 734 nm, 650 nm and 405 nm, in the presence of hydrogen peroxide and HRP. The latter frequency demonstrates a significant molar extinction coefficient and is generally employed for most ABTS assays. Stopping the reaction with acid does not alter the 405 nm spectrum allowing kinetic and endpoint methods to be measured at the same wavelength. Provided as a room temperature stable, single component ABTS solution satisfactory for quantitative analysis of HRP based systems.
