본문내용

Reverse-Phase Chromatography
 Stationary phase : silica- n-butyl, n-octyl, n-octyldecyl
 Mobile phase : polar solvent (acetonitrile, methanol)
 Application
- soluble in polar solvent (water)

Column selection : hydrophobicity, protein size
- hydrophobic, > 50 kDa : C4
- middle, 10 ~ 50 kDa : C8
- hydrophilic, < 20 kDa : C18

How can we enhance selectivity?
- ion-paring agent : 0.1% TFA (tetrafluoroacetic acid)
- buffer : phosphate buffer
