2/7 PCR & isolate DNA

Set up PCR to verify plasmid inserts

Isolate plasmid DNA from bacteria

Outside class: Begin collecting virgin females from the P- element lines this week

PCR reagents

• Invitrogen T7 Promoter Primer Catalog Number N560-02 (forward primer, 20uM)
• 5 µL sterile water
• PCR buffer
• 50 mM MgCl2
• 10 mM dNTP mix
• Taq polymerase (5U/µL)

PCR engine parameters

• 94 C 5 min
• 94 C 30 sec
• 55 C 30 sec
• 72 C 3 min
• repeat 30 x
• 72 C 6 min
• (protocol says 4C, should just be END) Note - can just stop, cold promotes condensation, and the product is sterile
