Table 1. Minibody/contaminant distribution throughout purification.

Stage Unbound Elute Clean
AG mini, HCP — DNA, ETX, lipid, dye
MMC HCP, DNA mini, dimer, HCP dimer, HCP
AX HCP mini, dimer, HCP HCP, DNA, ETX, virus
HA HCP mini dimer, HCP, DNA, ETX, virus

This table indicates trends and is not intended to suggest quantitative distribution. Lipid includes phospholipids, fatty acids, and steroids. Dye refers to pH indicator dyes used in cell culture. HCP = host cell protein; ETX = endotoxin.
