Optical Neutralization of Insulin


The "Neutralization of Insulin by Photocleavage in High Vacuum " is published in Chem. Commun.

Charge reduction and neutralization of electro-sprayed peptides is realized by selective gas-phase photocleavage of tailored covalent tags. We demonstrate this here for the first time for a large polypeptide, i.e. insulin. This is an important step towards the controlled neutralization, ionization of proteins, which will be required in novel matter-wave beam splitters and interference detectors for proteins.
