PCR verification for Uppsala-Sweden team

Helping the Uppsala team with a PCR verification of one of their assemblies.

Summed up their total construct length in pSB1x3 to 6566 bp.

• K1: C2 & C4 (x2)
• K2: C2 & C5 (x2)

Standard colony PCR settings:

• Elongation time: 10 min
• Annealing temp: 55 °C and 60 °C

PCR run ON.
