Methylisothiocyanate (CH(3)NCS) was photolyzed at 193 and 248 nm, and the resulting time-resolved infrared emission was observed. Similar experiments were performed on methylthiocyanate (CH(3)SCN) photolyzed at 193 nm. Previous work suggested that these isome...

Two methods for the determination of methionine in proteins have been used to estimate the extent of methionine sulfoxide obtained upon exposure of proteins to oxidizing agents. Both methods are based on prior treatment with cyanogen bromide, which attacks me...
