Suggested operating parameters for FPLC operation, gel filtration, and sample collection based on a GE Superdex 200 10/300 GL column
Procedure step | Flow rate (mL/min) | Approx. pressure (MPa) | Volume (mL) | Column fractiona |
---|---|---|---|---|
Equilibration | 0.6 | 0.6–0.7 | 4.8 | 0.2 |
Sample injection | 0.3 | 0.3–0.35 | 0.75 | 0.03 |
Elution before collection | 0.3 | 0.3–0.35 | 6.24 | 0.26 |
Fraction collection | 0.3 | 0.3–0.35 | 15.6 | 0.65 |
Regeneration | 0.6 | 0.6–0.7 | 21.6 | 0.9 |
Water rinse | 0.6 | 0.6 | 25 | 1.04 |
Ethanol storage | 0.6 | 0.6–0.7 | 25 | 1.04 |
Specific to Superdex 200 10/300 GL column with 24 mL packed bed.
Sample system pressures are for a column of moderate age. New columns will operate at 0.1 MPa less; older columns should be cleaned once pressures exceed 0.75 MPa. Volumes and column fractions are given to provide protocol programming guidelines following the Section 3 methodology.
