BioPEG Grids are hydrophilic SMART Grids that have been functionalized with polyethyleneglycol (PEG). The PEG
coating is intrinsically inert towards the adsorption of proteins, cells and other biomolecules, thus providing a
zero-background starting surface. Standard bio-conjugation chemistry (e.g. using biotin moieties) may be used to
covalently link biomolecules to the PEG surface.
To order SMART Grids, please make your selection below. For assistance in selecting the correct window size and thickness for
your applications, see our configuration page.
