The corresponding PDB (Protein Data Bank) format file is from Mike's immunoglobulin structure function site (http://www.umass.edu/microbio/rasmol/padlan.htm).
The first chrystal 3D structure of a complete immunoglobulin is that of B12, a human IgG1, anti-HIV1, determined in 2001 (PDB code: 1hzh in IMGT/3Dstructure-DB).
This IgG1 model is described in Fig. 1 in Anatomy of the Antibody Molecule by Eduardo A. Padlan, Mol. Immunol. 31:169-217, 1994.
It is a composite model of a F(ab')2 built from the Fab from 2ig2 and an Fc fragment from 1fc2. Part of the hinge region and other details are theoretically modeled.
