Description
| This dataset consists of a flow cytometry experiment from two cultures of Dinophysis acuminata. Cell samples were extracted from cultures that were saturated vs limited in its prey, Mesodinium rubrum, every two hours for 96 hours (4 days). Cellular DNA was stained with DAPI, which was then analyzed for particle scatter (forward, side) and fluorescence (405nm excitation, 440/50nm bandpass) on the Attune CytPix imaging flow cytometer, targeting ≥ 1000 Dinophysis events per sample.

Notes
| Flow cytometric data and in-flow light microscopy images. The cell_cycle.atx file contains all the data including both the flow cytometric and image data and can be viewed and accessed with the Attune Cytometric software. The data from this experiment are split into three portions: the fcs, images, and stats. The .fcs datasets include flow cytometry data that includes the fluorescence and scatter values for all triggered events in each sample. The images dataset includes a .zip file containing all the images captured under the flow cytometry gating strategy. The stats dataset includes a .csv table with summary statistics for each gate in each sample. |

Data Source
| Lab experiment covering two culture treatments (prey-saturated, prey-limited). Samples taken every 2 hours in triplicate from each treatment over 96 hours.
Samples were collected via pipet into Falcon tubes, centrifuged at 2800rcf for five minutes, fixed in 1% glutaraldehyde seawater solution for 45 minutes, re-pelleted (5 minutes, 2800 rcf), then stored in 1-mL ice-cold methanol at -20˚C for no more than 5 days. Prior to analysis, samples were centrifuged at 4000 rcf for 5 minutes. Pellets were washed in cold filtered seawater, resuspended in a staining buffer (filtered seawater, 1% Triton-X-100, 100 ug/mL RNaseA, and 0.5ug/mL DAPI), and incubated at 4˚C overnight before feeding into Attune CytPix. |
