See post for details on extracting DNA from eelgrass swabs from the FHL 2026 V. pec., eelgrass and mussel experiment!

Background info on the project

DNA Extraction of Eelgrass Swabs Info:

Samples processed

Started with one sample/treatment plus 2 DNA extraction blanks to test the protocol:

sample_id treatment_id treatment sample_type
S_ESW_01 ESW eelgrass + sw eelgrass_swab
S_EVP_03 EVP eelgrass + vp eelgrass_swab
S_EM_03 EM eelgrass + mussel + sw eelgrass_swab
S_EMVP_02 EMVP eelgrass + mussel + vp eelgrass_swab
S_Blank_01 NA NA NA
S_Blank_02 NA NA NA

Protocol notes:

Extraction Kit: Qiagen DNeasy PowerSoil Pro Kit (Cat: 47014)

Extraction Notes: here

Protocol was modified by Becca Maher specifically for swabs from eelgrass tissue (see link to notes above).

Eelgrass swab sampling protocol: here

Notes for next time:

  1. Turn on the heat block to 65C before starting protocol so it’s ready on time.

Results:

To check to see if this (new to me) protocol worked for these samples, I ran 1ul of each sample on the Nanodrop.

Results:

but this is just all DNA… not V. pec. Just wanted to check to see if there’s DNA from the samples before I process the remaining 28!
