title: GSM7349977: 27S CMCT and NaHCO3 replicated 1; Escherichia coli; OTHER
library_construction_protocol: The ribosomal particles were isoalate using a  20-40% gradients were made in a buffer consisting of 20mM HEPES KOH pH 7.5, 150mM NH4Cl, 1mM MgCl2 and 4mM BME. The NGS sequencing library was performed following the randomer workflow of the Selective 2'-hydroxyl acylation analyzed by primer extension and mutational profiling(SHAPE-MaP) protocol(Smola et al. 2015)
