REL PDBe PDBe PDBe 2012-01-04 2012-01-20 2012-01-27 2016-03-09 Three-dimensional reconstruction of another targeted individual antibody particle by individual-particle electron tomography (IPET). The reconstruction displayed three ring-shaped domains that corresponding to three domain of IgG antibody.

EM Specimens were prepared by optimized negative-staining EM specimen preparation protocol as described Zhang L. and Ren G, Journal of Lipid Research, (2010) 51, 1228-1236 and (2011) 52, 175-84. In brief, antibody was diluted to 0.01 mg/ml with deionized water. Aliquots (about 3ul) were applied to the 200 mesh glow-discharged thin carbon-coated EM grids (Cu-200CN, Pacific Grid-Tech, USA). The grid was washed by deionized water for three times, and then washed by 1% uranyl formate for three times before blotting to drying.
