DNA Extraction

- Incubate tails overnight at 56°C in DirectPCRLysis reagent plus Proteinase K (0.5 mg/ml) under constant agitation.

- Stop reaction at 85°C for 45 min.

- Spin for 1 min at 8000 rpm.

 

 

PCR reaction

- Note that the stock solutions containing Cre primers (TK139/TK141) and primers for the positive control (ADV28/29) should be at 100 µM. Store TK139/TK141 in small aliquots at -20°C. ADV28/29 is stable at 4°C.

- The stock solution containing Taq is at 2.5 U/µl.

- Prepare a reaction mix per tube/animal according to the following table
