Prep for Sequencing Protocol

Protocol
Difficulty
intermediate

Steps

1
Gather materials and label new tubes

Collect amplified samples, new tubes (excluding negative control), and exoSAP enzyme solution kept on ice. Label all new tubes clearly for organization.

2
Transfer amplified samples to new tubes

Transfer 5 microliters of each amplified sample into labeled new tubes. Return the original amplified samples to the fridge.

▶ 01:27
3
Add exoSAP enzyme and incubate

Add 2 microliters of exoSAP enzyme solution to each sample, wiping the tip before expelling due to viscosity. Cap, mix, centrifuge to collect, then place in thermocycler on exoSAP program.

4
Prepare new tubes for sequencing reactions

Obtain two new tubes per digested DNA sample to create separate forward and reverse sequencing reactions. Label sample numbers on the front and F or R direction on the back.

5
Set up sequencing reaction master mix

Add 10 microliters of water to all new sequencing reaction tubes, then add 3 microliters of digested DNA sample to both its forward and reverse reaction tubes using fresh tips for each transfer.

▶ 08:16
6
Add primers and finalize reactions

Add 2 microliters of the appropriate primer (forward or reverse) to each corresponding reaction tube. Cap all tubes, mix, and centrifuge to collect samples.
