Monitoring of active groups of cyanogen-bromide-activated paper discs used as allergosorbent.

The amount of active groups of cyanate esters and imidocarbamates present on cyanogen-bromide-activated paper discs were estimated. The protein-binding capacity of activated discs was found to be dependent on the amount of these active groups. The results suggested that monitoring of active groups on activated discs can help in preparing consistent allergosorbent for immunoassays.
