Azide-PEG4-Azide

作者：德尔塔日期：2022-04-27

Azide-PEG4-Azide PEG4 diazide (CAS# 101187-39-7) is a homobifunctional linker with two azide groups. It can be used for the synthesis of dimeric molecules with a hydrophilic core by Click chemistry.

Azide-PEG4-Amine

作者：德尔塔日期：2022-04-27

Azide-PEG4-Amine PEG4 amine azide (CAS# 134179-38-7) is a bifunctional linker with amine and azide functional groups. It is based on a tetraethyleneglycol core. The length of the PEG4 linker is 1.4 nm. Coumarin 343 is a blue emitting fluorophore that can serve as a FRET donor for fluorescein (FAM). This azide derivative can be conjugated with alkynes by Click chemistry. An extended linker arm between the fluorophore and the azide group enhances solubility, and provides spatial separation between the dye and the biomolecule. &nb
