1. Introduction
The sampling and storage of leaf samples for DNA extraction has a big impact on the final quality and quantity of the DNA extracted.

3. LEAF SAMPLE COLLECTION PROCEDURE
Please familiarise yourself with the contents of this kit and read through the following steps in this guide before sampling your leaves. It may be useful to practice sampling a few leaf discs first before starting on your test samples.
A. PROCEDURE USING THE BASIC LEAF CUTTING TOOL
5. Rinse the leaf cutting tool in water between each leaf and shake dry to avoid cross-contamination between samples.
6. Repeat steps 1 – 5 until you have collected all the leaf discs you require for your project. To confirm how many leaf discs you need for your project, please contact 3CR Bioscience at labservices@3crbio.com.
B. PROCEDURE USING THE ADVANCED LEAF CUTTING TOOL
- Record the ID of the sampled leaf onto the Plate Map provided.
- Rinse the leaf cutting tool in water between each leaf and shake dry to avoid cross-contamination between samples.
- Repeat steps 1 – 4 until you have collected all the leaf discs you require for your project. To confirm how
many leaf discs you need for your project, please contact 3CR Bioscience at labservices@3crbio.com.
4. PACKING YOUR LEAF SAMPLES FOR SHIPPING
5. Expel as much air from the bag as possible and then close the seal. This step seals in the remaining air around the samples and allows the desiccant sachets to absorb moisture from the sample to reduce the chance of fungal growth.

6. Pack the rack(s) into a secure box for shipping to 3CR Bioscience.
7. Prepare customs commercial invoice and book a shipment with your preferred courier making sure to take note of the tracking number. Alternatively, 3CR Bioscience can arrange the sample collection for you. Please contact your sales representative if you wish us to manage this on your behalf.
8. Complete an electronic plate map file and send this to labservices@3crbio.com along with the tracking number of your shipment. You will receive an email to confirm that we are aware you have shipped your samples. You will also receive an email once we receive the samples to confirm that we have them.
