Pyrene-PEG2-azide is a pyrene labeled PEG derivative containing an azide group which enables Click Chemistry labeling with any alkyne-bearing molecules and thus turns any molecule into pyrene-bearing probe. The hydrophilic PEG linker can increase solubility and facilitate attachment to biomolecules in aqueous solutions.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
