Difluorocarboxyfluorescein Cadaverine, 5-isomer

Overview

Difluorocarboxyfluorescein Cadaverine, 5-isomer (sold under Oregon Green™ 488 Cadaverine, 5-isomer name) is a carbonyl reactive building block used to modify carboxylic groups in the presence of activators (e.g. EDC, or DCC) or activated esters (e.g. NHS esters) through a stable amide bond. It also can be employed as a polar tracer and as a reactive dye for labeling proteins via a carboxylic acid moiety. Difluorocarboxyfluorescein Cadaverineis a fluorinated analog of fluorescein that overcomes some of the key limitations of fluorescein, including greater photostability and a lower pKa (pKa ~ 4.7 versus 6.4 for fluorescein), making its fluorescence essentially pH insensitive in the physiological pH range. Difluorocarboxyfluorescein Cadaverine, 5-isomer structurally is identical to Invitrogen’s Oregon Green™ 488 Cadaverine, 5-isomer. Please contact us for GMP-grade inquiries.
