DNA from IDT will typically be delivered in a white flaky substance, which need to be resuspended, before the DNA is ready for use

Materials

• Table centrifuge

• EB/TE buffer

• Genes/Primers from IDT or other DNA provider

Procedure

1. Quickly spin the DNA down in the table centrifuge

2. Calculate the amount of EB buffer need to dilute the gblocks to a desired concentration. Important: gene fragments and primeres are not diluted to the same concentration: The concentration of gene fragments is usually 25 ng/μL and for primers it is 100 μM.

3. Genes/Primers from IDT or other DNA provider

   • DNA from IDT usually comes in dried flakes of 500 or 1000 ng of DNA. To achieve the desired concentration (usually 25 ng/μL) the needed amount of EB buffer is 40 μL (for 1000 ng samples) or 20 μL (for 500 ng samples)

   • In order to calculate the the molar amount of primer, use the NEB calculator

4. Add the calculated amount of EB buffer

5. Store the resuspended DNA at -20°C

Basic protocol on plating of the fungi.

Materials

• Agar plates with media of interest

• Sterile toothpicks

Procedure

Plating using mycelia

1. Open the plate containing the mycelia from the species of interest

2. With a sterile toothpick, scratch the surface of the mycelia.

3. Spike the new agar plate with the toothpick.

4. Repeat steps 1-3 times. Three inoculation points should be made in the agar making forming a triangle.

5. Put the plate into a plastic growth bag.

6. Place growing bag into the incubator.

Plating using spores

1. Touch the sterile tooth pick in the spore suspension.

2. Spike the new agar plate with the toothpick.

3. Repeat steps 1-3 times. Three inoculation points should be made in the agar making forming a triangle.

4. Put the plate into a plastic growth bag.

5. Place growing bag into the incubator.
