Analysis of Antibody Aggregate Content at Extremely High Concentrations Using Sedimentation Velocity with a Novel Interference Optics
Fig 1
Interference detectors of the Optima XL-I ultracentrifuge (left) and the custom-built Aida ultracentrifufe (right).
The larger camera surface of Aida allowed for a higher optical magnification factor of 2 vs. 1.75 in the XL-I centrifuge after adapting the lens system accordingly. Additional improvements are described in the text.
