TAEL 2.0
Multi-Component SwitchTAEL 2.0 is a modified version of the TAEL/C120 optogenetic transcription system in which both the TAEL transcriptional activator and the C120 regulatory element were altered. In zebrafish embryos, blue light induces TAEL dimerization, binding to the C120 element, and transcriptional activation to drive light-inducible gene expression.
