Characterizations of ac-LK and Tamra-LK. A Chemical structures and amino acid sequences of acetylated and Tamra-labeled LK. B-E The HPLC chromatograms and MALDI-TOF mass spectras of ac-LK (B, C) and Tamra-labeled LK (D, E). Both CPPs were analyzed by HPLC with 70–75% of ACN (0.1% TFA) (> 97% purity) at 220 nm. Ac-LK; MS [M + H]+ 3648.62 (calcd), 3648.25 (found), Tamra-LK; MS [M + H].+ 4018.75 (calcd), 4018.93 (found)
