Published Workflows
Objective: Engineer and apply fluorescein-based adaptor strategies to control SynNotch signaling and downstream gene expression in mammalian cells using chemical, spatial, and matrix-based extracellular cues.
Why it works: The workflow uses a fluorescein-binding SynNotch receptor together with different fluorescein-based adaptor formats so that the same receptor platform can be triggered by chemically activated, photo-uncaged, or ECM-associated inputs.
