Rhodamine B-PEG2k-N3

C₂₈H₃₁ClN₃O₂(CH₂CH₂O)_nC₂H₄N₃

Polyethylene glycols (PEGs) are FDA approved hydrophilic polymers. They are non-toxic, non-immunogenic and non-antigenic, and are widely used in a variety of biomedical applications such as bioconjugation, drug delivery, surface functionalization, and tissue engineering. Rhodamine B-PEG2k-N3 is a heterobifunctional PEG with a Rhodamine B fluorescein dye and an azide endgroup. Rhodamine B has peak fluorescence emission at 572-575 nm.
