3-Aminotyrosine

Product Description

3-Aminotyrosine is an unnatural amino acid that induces red shift when incorporated into fluorescent proteins and fluorescent protein-based biosensors. Causes spontaneous and efficient red shift of GFP in HEK293T cells, shifting excitation and emission maxima by 56 and 95 nm respectively. Induces red shift in a range of fluorescent proteins containing tyrosine-derived chromophores, including teal fluorescent mTFP1, yellow fluorescent Citrine, and circularly permuted YFP and GFP. Also induces red-shift in fluorescent protein-based biosensors, including iGluSnFR (a glutamate sensor), iGABASnFR (a GABA sensor), dLight1.2 (a dopamine sensor) and iATPSnFR1.1 (an ATP sensor).
