Introduction
HIC is a versatile technique and can show high selectivity to individual molecules according to their exposed hydrophobic zones. It is particularly useful for intermediate and final-stage purifications.
Butyl SepFast™, Phenyl SepFast™, and Octyl SepFast™ are hydrophobic interaction chromatography (HIC) adsorbents with carbon chains of C4, C6 (benzene ring), and C8, respectively. They are specially designed for the purification of biological molecules based on their hydrophobicity profiles.
HIC media requires much milder purification conditions than reversed phase chromatography (RPC) media. Hence biological activity can be maintained in HIC separations unlike RPC operations.
HIC media normally binds at moderate to high salt concentrations. It is therefore logical to place a HIC step after an IEX step where molecules are usually eluted at high salt conditions.
SepFast™ HIC media offers a broad range of choices from C4 to C8. Generally speaking, the longer the carbon chain, the higher the surface hydrophobicity.
Biotoolomics HIC media gives you:
- High sample loading capacity
- High separation power
- Available at all pack sizes from analytical up to full manufacturing scale.
- Chemically stable Agarose base matrix.
- Can be produced in high and low ligand densities, alternate crosslinking levels and different bead sizes to optimise the media to the separation.
- All versions can be scaled up and produced for GMP use
- More choices than other suppliers.
The feature and selection guide is listed as follows:
| 4HF serial (50µm - 150µm) | 6HF serial (50µm - 150µm) | Large Beads (150µm - 350µm) | HighRes (25µm - 50µm) |
| The above HIC media is designed to purify most medium to large proteins | The above HIC media is designed to purify peptides or smaller proteins | The above HIC media is designed to purify proteins from crude or viscous samples | The above HIC media is designed to purify proteins that require high resolution |
