Functional Parameters

Figure 1. Single stranded DNA harvested from phage and run on a gel. The higher bands are phage genomic DNA while the lower bands at roughly 2-3kb correspond to the expected plasmid size.

The f1 origin was tested by comparing single strand DNA harvest using part of the [http://2010.igem.org/Team:Washington/Protocols/KunkelCapD Kunkel's mutagenesis] protocol. CJ236 cells were infected with M13K07 helper phage. The CJ236 cells varied in the present or absence of the f1 origin on the pSB1A3 or pSB3K3 plasmid. The SS DNA harvest was then run on a 50ml 1% agarose gel at 90V for 45minutes. As is clearly visible on the gel to the right single strand DNA of the plasmid is only made when the f1 origin is present.
