Figure 3From: New cell line development for antibody-producing Chinese hamster ovary cells using split green fluorescent proteinRelationship between the q Ab and green fluorescence intensity in 30 selected clones. Median green fluorescence intensity (GFP mean) and qAb were measured by flow cytometry analysis and ELISA, respectively. The qAb and GFP mean (X, Y) pairs for each clone were plotted to calculate the correlation coefficient (R2).Back to article page
