CEP

Key Product Details

Product Description

CEP is a chemoproteomic reagent. It is a clickable electrophilic purine used to directly quantify protein-RNA interactions on proteins through photoaffinity competition with 4-thiouridine (4SU)-labeled RNA in cells. It is a cysteine reactive probe used in photo-activatable-competition and chemoproteomic enrichment (PACCE) method for global quantification of protein-RNA interactions in living cells.
