Sequencing protocol (Sequenase 2.0 Kit)

1- 5 ml minilysate (from boiling method, 1/10 vol)

Add 15 µl Mix 1.

Incubate at 37o C for 30 min.

2- Add 10 µl (NH4)OAc (7.5 M) + 60 µl EtOH, or 12 µl 0.5 M (NH4)OAc (pH 4.5) + 75 µl EtOH.

Incubate 10 min in dry ice/EtOH bath.

Spin 15 min in Microfuge in cold room.

Wash pellet 2X with 70% EtOH.

Dry pellet in SpinVac.

3- Add 11 µl Mix 2.

Incubate at 37o C for 15 min.

Leave at room temperature for 10-15 min.

4- Add 4 µl Mix 3.

Incubate 5 min at room temp.

Place on ice.

5-Add 2.5 µl dd/dNTPs (dA, dC, dG, dT) per well of microtiter plate.
