Colony PCR is a convenient high-throughput method for determining the presence or absence of insert DNA in plasmid constructs. Individual transformants can either be lysed in water with a short heating step or added directly to the PCR reaction and lysed during the initial heating step.
The key steps to colony PCR are: 1) design primers to detect the presence of your insert; 2) set up a standard PCR reactio n (primers, dNTPs, polymerase) using the supernatant of lysed bacteria as template; and 3) run your PCR product on a gel to analyze product size.
Colony PCR is a method for rapidly screening colonies of yeast or bacteria that have grown up on selective media following a transformation step, to verify that the desired genetic construct is present, or to amplify a portion of the construct.
Colony PCR is a method used to screen for plasmids containing a desired insert directly from bacterial colonies without the need for culturing or plasmid purification steps. With SapphireAmp Fast PCR Master Mix, the colony PCR workflow is further improved and can be set-up with three basic steps: Pick a colony, "Poke" to a replica plate, and
16 de jun. de 2023 · Colony PCR allows researchers to quickly check that the clones obtained after the transformation step of their molecular cloning protocol, have the desired genetic insert. It uses lysed bacterial or yeast cells as a DNA template in a PCR reaction, saving time and resources in the lab.
Prepare the PCR mastermix, and aliquot to PCR strip-tubes. Use P20 multichannel to add 1 ul colony lysate to PCR mix. Run a PCR reaction on the thermocycler with a program that matches the PCR kit, necessary extension time, and an anneal temperature suitable with your PCR screening primers.
