Collection:

Collection ID:CO001951
Collection Summary:Alexandrium minutum cells were collected by vacuum filtration onto GF/F filters and quenched with liquid nitrogen. Frozen cells with filters were stored in foil (previously muffled for 3 h at 450 °C) at -80 °C until extraction.

Sample Type:Algae
Collection Method:Filtration and Freeze
Storage Conditions:-80℃

Treatment:

Treatment ID:TR001970
Treatment Summary:Twice, first at the start of the experiment and again 24 h later, 1.5 mL of either 0.2 µM copepodamides (copepod cue) in DMSO (treatment, n=20) or DMSO alone (control, n=20) were added aseptically to 300 mL cultures of Alexandrium minutum resulting in a final concentration of 1 nM copepodamides.

Sample Preparation:

Sampleprep ID:SP001964
Sampleprep Summary:Non-polar extracts were dissolved at a concentration equivalent to 2.27 x 10^7 A. minutum cells mL-1 in dimethyl sulfoxide d6 (99.9% atom d6-DMSO; Cambridge Isotope Labs) containing 0.1% trimethylsilane (TMS), as internal standard. The media blank extract was prepared in the smallest volume of solvent possible (175 µL). The non-polar extracts were transferred to 3 mm NMR tubes, and analyzed using a Bruker Avance IIIHD 800 MHz NMR spectrometer equipped with a 3 mm triple resonance broadband cryoprobe. Spectra of non-polar extracts were acquired using a simple 1H NMR experiment (Bruker zg30 pulse sequence) with a spectral width of 9.6 kHz centered at 4400.00 Hz over 320 scans. One treatment replicate was lost and therefore its spectrum was not acquired.
