BODIPY-PEG-Mal

Boron-dipyrromethene-poly(ethylene glycol)-maleimide (BODIPY-PEG-MAL) is a functional dye combining a BODIPY chromophore, a defined-length PEG spacer, and a maleimide conjugation terminus. The PEG spacer is available in discrete chain lengths with different degrees of polymerization. The maleimide can add to cysteine thiols or other thiolated modules, providing a handle for conjugation at thiol sites. The PEG spacer separates the chromophore from the target attachment site. Chain length can be selected in relation to labeling position, local environment, and conjugate dispersion.
