PC Azido-PEG3-OH is a photocleavable PEG linker featuring an azido moiety for copper-catalyzed click chemistry with alkyne, DBCO, BCN, and an OH group which may be further derivatized or functionalized. This structure allows for efficient photorelease of linked molecules, typically achieving over 90% cleavage in 5-25 minutes using a near-UV lamp. The PEG3 spacer increases the water solubility of the molecule.
Usually ships within 24 hours.
