Live Cell Analysis of Fluorescent Co-Culture Assay
Measure % RFP Positive Cells in Samples Containing GFP, 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.
