The present invention relates to a method for producing CRM197 recombinant protein in cells. The method comprises culturing a cell comprising an expression plasmid with a polynucleotide and inducing expression of the CRM197 protein.

CRM197 protein expression

A bidirectional digital communication circuit and a bidirectional digital communication method for combining multi-channel signals to a duplex digital communication system apply time division multiplexing. The signals can be unidirectional and bidirectional; signals relationship is not necessary. The direction detector circuit determines signal directional automatically to avoid the signal loop. It's suitable for applying to fiber, cable or wireless communication system which is needed to minimize the communication channels.
