Plasmid amplification is provided in Escherichia coli bacteria cells. Plasmid linearization by restriction cleavage can be ordered as a follow-up service. Such an operation is recommended especially when the plasmid is used as a PCR standard. Amplified plasmids are delivered either in midiprep or maxiprep quantities. Typical yields are stated below.
If the plasmid DNA is intended for use as a PCR template, it is recommended to use it as a linear DNA. A circular plasmid mostly has a supercoiled conformation, where the target sequence is less accessible for primers and for polymerase.
This service is recommended when it is necessary to verify whether a correct sequence was cloned in, whether plasmids were not misidentified (mistaken by accident), or to verify that there are no errors in the plasmid sequence.
