Bacterial Origin Cloning: We currently have four alternative origins of replication for use in bacteria. Our bacterial origins of replication are normally flanked by two SwaI restriction sites. They will function if they are inserted in either orientation between these two sites.

 

Phage and Mammalian Origin Cloning: We also have a range of other origins of replication, including the SV40 origin of replication for mammalian cells and the F1 phage origin of replication that can be used to create single stranded DNA. These are currently available in either the SbfI or PacI sites respectively, however, they can be inserted into other positions on request.
