RS/tRNA Additional Notes
Tested in live cell (HeLa):
Showed incorporation in HA-IFITM3-F8TAG at 50uM of exo-BCNK, endo-BCNK and 2'-aTOCK. Expression in presence of ncAA for 16 hours then depleted growth media for 6 hours after which they were labelled for 30 minutes with tetrazine flurophore. 2'-aTOCK was most efficiently incorportaed into all portien at higher protien expression levels compared to Exo-BCNK.
Expression of GFP-Y39TAG, showed incorporation for 2'a-TOCK was concentration independent.
