From: Stability and assembly in vitro of bacteriophage PP7 virus-like particles
Purification of DTT/urea-disaggregated PP7 and 2PP7 coat protein by gel filtration chromatography in 10 mM acetic acid, 50 mM NaCl (about pH 4). To estimate the molecular weight of the putative dimer species, bovine serum albumin (68 kD), ovalbumin (43 kD), chymotrypsinogen (25.7 kD) and hen lysozyme (14.4 kD) were used as standards. They peaked at fractions 14, 18, 22 and 26 respectively.
