I think free alkalies react with CNBr to form alkali bromide and alkali 
cyanide.  i.e. You often dispose of excess CNBr by mixing with dilute 
NaOH.  I don't know if 300mM is enough, but it probably reduces the 
amount of CNBr reacting with protein so that there might not be enough 
(or any) left.

Sincere regards,
