Optogenetic proteins and fluorescent dyes should be carefully selected to avoid optical crosstalk and consequent disruptions in readouts or cellular activity.

Quoted textsource-backed

Therefore, optogenetic proteins and fluorescent dyes should be carefully selected to avoid optical crosstalk and consequent disruptions in readouts and/or cellular activity.

Claim 3limitationsupports2023Source 1DOI PubMed

Spectral congestion is a major obstacle in all-optical cardiac electrophysiology because overlap among excitation, activation, and emission spectra causes optical crosstalk.

Quoted textsource-backed

However, spectral congestion poses a major obstacle, arising due to the overlap of excitation/activation and emission spectra of various optogenetic proteins and/or fluorescent dyes, resulting in optical crosstalk.
