a, d Lamellar cylinders composed of M13 bacteriophage (6.5 mg/mL) in the presence of dextran (20 mg/mL) without (a) and with (d) a 10-T magnetic field; (i) wide-view optical microscopy image, (ii) magnified optical microscopy image, and (iii) 3D reconstruction of confocal laser scanning microscopy (CLSM) images with negative fluorescent contrast. b, e Phase behavior of the virus assembly upon changing the concentrations of the virus and dextran without (b) and with (e) a 10-T magnetic field. c, f Diameter distributions of the lamellar cylinders at the equilibrated state, formed from [virus] = 6.5 mg/mL and [dextran] = 18 ~ 22 mg/mL, without (c) and with (f) a 10-T magnetic field. All assembly experiments were conducted in tris-buffered saline (pH 7.5, 50 mM of tris, 150 mM of NaCl) within a glass sandwich cell at 20 °C. The box-whisker plot of diameter is based on > 100 different lamellar cylinders under the same conditions, using the whisker method with min and max data and the Tukey quartile method.
