Protein purification

Find out about the protein purification services and facilities available within the Biotechnology Facility.

We currently have two AKTA purification instruments available to book, an AKTA Go and an older AKTA FPLC. These can be booked by users as a package to include use of all buffers, columns, reagents and SDS-PAGE analysis, or booked for use of the AKTA only, with users providing reagents and columns.

Training is available and must be undertaken before users are able to book to use these instruments themselves.

Purifications can also be run as a service by the Biotechnology Facility technical team. Please contact the team for details.

This instrument can run a single column with four inlet pumps. It also has a sample loading pump for easy loading of larger sample volumes. Methods are available for each column, or individual runs can be controlled manually. For smaller sample volumes (up to 5 ml) a variety of sample loading loops are available.

This instrument can run a single column and has two buffer chambers. It does not have a sample loading pump, but samples of up to 150 ml can be loaded using a super loop. This can also be run manually or using pre-programmed methods.

Columns available to use on these two systems are shown in the table below. If a desired column is not listed please discuss this with us. We are always looking to expand our column library to suit the needs of our users.

Columns available

Below is a table of columns we currently have available. If there is a column that you require that is not on the list please contact us.

Column Application
HisTrap FF (1 ml, 5ml) Affinity chromatography for the purification of his tagged protein
HiTrap Q FF (1ml, 5 ml) Anion exchange chromatography, for protein separation by charge
HiTrap Q HP (1ml) Anion exchange chromatography, for protein separation by charge
HiTrap SP FF (1ml) Cation exchange chromatography, for protein separation by charge
HiTrap Phenyl HP (1ml) Hydrophobic interaction chromatography, for protein separation by hydrophobicity
Superdex 200 10/300 increase Size exclusion chromatography, for protein separation by size (maximum load 0.5mL)
Superdex 200 16/600 Size exclusion, for protein separation by size (maximum load 5 mL)
