Abstract
18S Metabarcoding PCR Protocol using Invitrogen Platinum Hot Start PCR 2X Master Mix (REF 13000014) buffer.
Preparing the PCR tubes
Preparing the PCR tubes
Label PCR tubes and place them under a UV light for Duration00:10:00 .

10m
Preparing the master mix
Preparing the master mix
Add Amount10 µL of Invitrogen Platinum Hot Start PCR 2X Master Mix (REF 13000014) buffer and Amount8 µL of molecular water to a 1.5 mL tube PER NUMBER OF SAMPLES i.e., for 4 samples, add 40 uL of buffer and 32 uL of molecular water to a 1.5 mL tube.
Mix well using a vortex, then centrifuge.

Transfer Amount18 µL of the master mix to each PCR tube.

Transfer Amount5 µL of the DNA template to each PCR tube.

Transfer Amount2 µL of the Metabarcoding Primer to the assigned PCR tube. Immediately place primers on a PCR Cooler Rack after use.

Mix the samples well using a vortex, then briefly centrifuge them using a microcentrifuge or platefuge to ensure all contents are at the bottom.
Place samples in a thermo cycler and set to a PCR protocol. Set the thermo cycler to use a heated lid and wait until the lid and block are close to the temperature. See 8.1 for thermo cycler specifications.
Tip: In the Bik Lab, select protocol “METAB-HS” on thermo cycler.
METAB-HS Protocol:
Lid: 105°C
Volume: 25 μL
1. 94°C, 3:00
2. 94°C, 0:45
3. 50°C, 1:00
4. 72°C, 1:30
5. GOTO step 2, 34X
6. 72°C, 10:00
7. 4°C, ∞
Close the thermo cycler lid well.
