For other salt forms please inquire. 2',2''-Di-c-didGMP is an analogue of the bacterial second messenger c-diGMP (Cat. No. C 057) which selectively binds the c-diGMP class II riboswitch over the class I riboswitch. It can be useful for discriminating between these two classes of c-diGMP-binding RNAs and for studying RNA-based c-diGMP signalling. Detailed technical information available.
