Live cell analysis of fluorescent co-culture assay
Measure percentage RFP Positive Cells in Samples Containing Green Fluorescent protein (GFP), Red Fluorescent Protein (RFP) and Non-Expressing Cells
A 96-well plate containing samples with varied % of RFP, GFP and non-expressing HeLa cells were counted using Celigo. Bright field, green fluorescence and red fluorescence channels were used.
Step 1. Acquire & view images on Celigo image cytometer

View whole-well cell images
Double click any well on the well map to display whole-well images. Zoom in to see details as shown below in cell image examples.

Step 2. Gate and circle counted cells automatically

Celigo gating and segmentation interface
Overlay of bright field, GFP+ and RFP+ cells identified by Celigo image processing software. GFP vs RFP intensity scatter plot is also shown. When the gate on the scatter plot is modified by dragging, the counted cell image is updated automatically.

Step 3. Review plate level results for each of the wells in the 96-well plate

Results are displayed in a plate-based format
Step 4. Export results for each of the wells in the 96-well plate and produce data plot
