PCR (pg10)
An overlap PCR was done to combine the two separate parts of the PGA gene.
Make a more negatively charged biofilm.
A band of 3000 bp can be seen.

PCR Thermocycle.
PCR product was loaded (1 µL product + 4 µL H2O + 1 µL 6X loading buffer) on 1% agarose gel with 1:50000 SERVA DNA Stain G and gel was ran for 30 min at 100 V. Multiple bands visible on the gel.
