Lab Plan for Holobiont Integration Project

Lab Plan for Holobiont Integration project

Protocols

Tissue extraction for molecular work
Beadbeating protocol: “Sample Prep” in K. Wong’s post
Separating symbionts from host in a tissue slurry: Protocol

DNA & RNA extraction
Protocol: Zymo-Duet

To test RNA and DNA quantity: Qubit
To test RNA quality: TapeStation
To test DNA quality: Gel Electrophoresis

Tissue extraction for physiology
Airbrushing: HIMB Protocol

Chlorophyll concentration
Following the protocol in: Wall et al 2018

Lipid content
Following Chris Wall’s protocol: Lipids
Check on these supplies:

  • Chloroform ACS grade
  • Methanol ACS grade
  • 0.88% KCl
  • UHP grade 5.0 nitrogen
  • Glass fiber filters
  • aluminum pans
  • large and small amber vials
  • cork borer and sharpener

Surface area
Wax-dipping: Following Stimson and Kinzie 1991
Method should vary with species of coral (depending on coralite structure), but single wax dip is the most effective (Veal et al 2010).
Small corallite (Porites sp., Stylophora sp.) structure - single wax dip
Acropora sp. needs double wax dip to seal deep corallites
Complex corallites (Goniastrea sp.) - single wax dip

Cell counts
“By-hand” Protocol: Symbiont Density
Flow Cytometer:
Prep cells

Total protein
Protocol: Pierce BCA

Dry biomass
Portions of the tissue slurry were dried (60 °C) to calculate dry biomass.
Protocol: ___

Ash-free dry weight
Portions of the tissue slurry were baked in a muffle furnace (4 hours at 500 °C) to calculate ash free dry weight as the difference between dry weight and the ash weight
Protocol: __
Can be done in the lipid protocol
