  1. Stock Solution:

    • 10 mM Tris-HCl (pH 8.2), 1 mM EDTA, 25 mM NaCl 

      • 100 ug/ml Proteinase K (add just before use) 

      • DNA extraction buffer: 

    • Proteinase K (10 mg/ml) 

  2. Method:

    • Put fly into 1.5 ml tube and keep on ice. 

    • Crush with 50 ul of DNA extraction buffer using pipet tip 

    • Centrifuge for 1 min at maximum speed 

    • Transfer supernatant in PCR tube 

    • Incubate for 30 min at 37°C 

    • Incubate for 5 min at 95°C 

    • Puton ice immediately 

    • Store at -20°C
