Description

Description: OG488 maleimide is the same molecule to Oregon Green® 488 maleimide (Invitrogen #O6034, Oregon Green® is the Trademark of Invitrogen). This fluorinated analog of fluorescein has higher photostability and a lower pKa ~ 4.7 while fluorescein maleimide has pKa ~6.4. The decreased pKa of OG488 maleimide makes its fluorescence essentially pH insensitive in the physiological pH range. This thiol-reactive OG488 maleimide can be used to make bright green fluorescent bioconjugates with excitation/emission maxima ~496/524 nm. It is an excellent replacement to fluorescein maleimide that has severe pH dependence and low photostability.
