Fluorescein-PEG4-Acid Chemical Properties,Usage,Production

Description

Fluorescein-PEG4-Acid is a xanthene dye with excitation/emmission maximum 494/517 nm and a free terminal carboxyl acid. Terminal carboxylic acid can react with primary amine groups in the presence of of activators (e.g. EDC, or HATU) to form a stable amide bond. It be used as quantum yield standard. Hydophilic PEG spacer increases solubility in aqueous media and reduces steric hindrance during binding.

Uses

Fluorescein-PEG4-acid is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
