Untreated paper substrates: prepare reactions
Sample prep
guidelines
• If you are processing a blood sample collected on untreated paper substrate,
make the punch as close as possible to the center of the sample to ensure optimum
peak intensity. Increasing the size of the punch may cause inhibition during PCR
amplification.
• If you are using a Bode Buccal DNA Collector
™
,
make the punch as close as possible to the tip of the
DNA collector to ensure optimum peak intensity.
Increasing the size of the punch may cause
inhibition during PCR amplification.
• For manual punching: Place the tip of a 1.2 mm
Harris Micro-Punch on the card, hold the barrel of
the Harris Micro-Punch (do not touch the plunger),
gently press and twist 1/4-turn, then eject the punch
in to the appropriate well on the reaction plate.
• For automated punching: Please refer to the User Guide of your automated or
semi-automated disc punch instrument for proper guidance.
Prepare the
reactions
1. Add Prep-n-Go
™
Buffer (Part no. 4467079) to the reaction plate:
2. Add samples to the reaction plate:
3. Centrifuge the plate to ensure the punches are immersed in the Prep-n-Go
™
Buffer.
