Fig. 2From: Easily-controllable, helper phage-free single-stranded phagemid production systemGelRed-stained 1% agarose gel image of ss DNAs produced by arabinose induction. The phages were produced by arabinose at indicated concentrations when the OD610 values of E. coli cultures (HB101/VCSM13ΔPS(PBAD-pII) bearing pBS189R-BsmBI or pSB189L-BsmBI) reached between 0.4 and 0.5. The reverse image is shown. Ara, arabinose; SM, 1 kbp ladder DNA size markerBack to article page
