Hediye Erdjument-Bromage

Hi Nerea,

You should be able to use alpha cyano hydroxycinnamic acid (ACCA) with the polymer PEG. See attached.

As Hediye Erdjument-Bromage suggested to you alpha cyano hydroxycinnamic acid , it is good matrix for PEG.

However if the molecular weight of your compound is higH, you can also try sinapic acid.
