RS/tRNA Additional Notes
In E.coli, produced 6-12 mg/L sfGFP(150) with fidelity verified by MS and reactivity with tetrazines. Also incorporated a closely related ncAA with a TCO ring.

In HEK-293 cells, ncAAs were incorporated into an mCherry-eGFP construct, position 128 of the EGF receptor, and the nuclear protein jun in a jun-mCherry construct. Both extracellular and nuclear proteins reacted with a tetrazine label.
