FAR-RED FLUORESCENT PROTEINS WITH IMPROVED DETECTABILITY BY RED EXCITATION LIGHT

摘要

Aspects of the present disclosure are directed towards far-red monomeric fluorescent proteins that have a high level of brightness such that the proteins are visible over the autofluorescence aspects of tissue. In certain embodiments, the fluorescent proteins are derived from Entacmeae quadricolor. The fluorescent proteins are implantable in the cell and can be excited by light of at least 600 nm.
