m-dPEG®4-acid, product number QBD-10234, is a short, methyl-capped, discrete chain length polyethylene glycol (dPEG®) spacer. The reactive end of the molecule terminates in a propionic acid group. The terminal propionic acid moiety can be coupled directly to free amines using EDC or another carbodiimide. Alternatively, the reactive end can be functionalized with N-hydroxysuccinimide (NHS); 2,3,5,6-tetrafluorophenol (TFP); 2,3,4,5,6-pentafluorophenol (PFP); or some other activating agent for reaction with amines.
m-dPEG®4-acid can modify amine-functionalized surfaces (carbon nanotubes, other nanoparticles, quantum dots, etc.) or free amines on biomolecules. When used to coat surfaces or modify biomolecules, m-dPEG®4-acid reduces, and often eliminates, non-specific binding and increases hydrophilicity. Please note that modification of surface amines on biomolecules with this uncharged, methyl-capped dPEG® spacer may alter the overall charge of the resulting conjugates.
In published scientific reports, m-dPEG®4-acid has been used in the following applications:
surface modification of polyelectrolyte multilayers;
thin films used for the detection of viable pathogenic microorganisms; and,
peptide modification.
