"This robot is awesome for setting up long and laborious lab assays with lots of repetitive steps. When using the silica-based QIAprep Spin Miniprep Kit, a protocol is contained in the QIAprep Miniprep Handbook, in Appendix C: Special Applications. to bind and remove something. Open circular plasmid, resulting from single strand nicks, usually migrates slower in agarose gels and forms (faint) bands above the supercoiled plasmid DNA band. To overcome this, continue mixing the solution by inverting it gentlyuntil a homogeneous blue suspension is achieved. Monarch Plasmid Lysis Buffer (B2) is designed for use with the Monarch Plasmid Miniprep Kit (T1010S/L). Do you have a protocol for the isolation of plasmid DNA from Agrobacterium?
