Azido-PEG3-carboxytetramethylrhodamine 110 conjugate, Thermo Scientific Chemicals

Description

Azido-PEG3-carboxytetramethylrhodamine is used as a water soluble azide functionalized- TAMRA dye. The water-soluble PEG spacer minimizes the interaction between the dye and the biomolecule to be labeled, used to detect or label alkyne- or cyclooctyne-containing molecules or biomolecules by fluorescence spectroscopy following an azide-alkyne click chemistry reaction.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
