a Gel-permeation chromatography (GPC) analysis of PcLs with 8, 16, 32, 64, 128 repeating units. b Combined MALDI-TOF mass spectra of PcLs encoding the letter (E, 1201.5 Da), two-letter word (SE, 2082.9 Da), four-letter words (SEQU, 3920.4 Da and ENCE, 3996.5 Da), 64-bit word (SEQUENCE, 7674.5 Da), and 128-bit word (SEQUENCESEQUENCE, 15105.3 Da). The peak was assigned to a [M + Na]+ ion. c MALDI-TOF spectra of 64- and 128-bit PcL showing no deletion errors or contamination of lower molecular-weight fragments.
