Supplier:
Adipogen
Description:
Photo-stable fluorescent probe (Ex: ~560nm; Em: 575nm) for the detection of nitric oxide (NO) in presence of oxygen, resulting in a triazolo-rhodamine analog (DAR-4M T) that exhibits about 840-fold greater fluorescence quantum efficiency. Suitable probe for monitoring RNS production, but not NO alone. Stable in a pH range of 4-12. Detection limit ~10nM.

Catalog Number:
(IC04821809)
Supplier:
MP Biomedicals
Description:
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.
