How the tissue samples were obtained in the
field.
Only a small bit of meristematic
tissue is required to extract the DNA.
After measuring the size of the
crown a pocket knife was used to remove a small sample of tubercle.
 |
The blade was wiped clean with
a paper towel and then with an alcohol wipe in between each sample.
 |
Each tissue sample then went
into a snack-sized ziplock bag with the location and specimen number
recorded on the bag with a permanent marker.
After being collated by specimen number they
were placed in a larger plastic ziplock bag and stored on ice in a
cooler until we reached the lab at UNAM.
