Vector Labs is closed to observe Juneteenth (US Holiday) on Wednesday, June 19th.
We will be back in the office on Thursday. We will respond to emails upon our return. Have a wonderful day.

O-propargyl-puromycine (OPP) (CCT-1407)



O-propargyl-puromycin (OPP) is an alkyne analog of puromycin that is efficiently incorporated into newly translated proteins, which are rapidly turned over by the proteasome and can be visualized or captured by copper(I)-catalyzed azide-alkyne cycloaddition. Unlike methionine analogs, OPP does not require methionine-free conditions and, uniquely, can be used to label and assay nascent proteins in whole organisms.
