Section 4. Anion Exchange Separation of Protein Standards
The starter kit enables you to learn to use the DuoFlow Maximizer or Pathfinder
systems by programming and running separation of a premixed anion exchange
standard containing equine myoglobin, conalbumin, chicken ovalbumin, and
soybean trypsin inhibitor, using a 1.3 ml UNO Q1 column (catalog #720-0001).
Equine myoglobin is not retained on the UNO Q1 column and elutes in the void
volume. Conalbumin, chicken ovalbumin, and soybean trypsin inhibitor bind to
the column and require increased salt concentrations for elution. Separation
requires approximately 6 minutes.
