Figure 10. Retention of tdTomato and GFP intrinsic fluorescence. A-B compares freeze substitution (A) and formalin (B) for impact on tdTomato intrinsic fluorescence, while panels C and D compare GFP fluorescence. There was little obvious difference for tdTomato fluorescence, while GFP fluorescence is essentially eliminated by freeze substitution.
