General description

Escherichia coli is a non-pathogenic, facultative anaerobic flora present in the intestine of human. It belongs to the genus, Escherichia, which consists of motile gram-negative bacilli.

Application

Escherichia coli has been used:
  • in the isolation of DNA from lyophilized cell
  • in the preparation of crude cell lysate for developing scalable purification method for recombinant protein A
  • as test proteome for comparative electrophoresis
