Protein Purification

Design an effective purification strategy to obtain high purity functional protein.

PEF utilises a wide range of capabilities to purify different types of protein from both recombinant and native sources. Taking into consideration the end-use of the protein, a purification strategy is designed to achieve high purity and stable protein. PEF conducts small-scale screening to determine optimal resin and buffer, develops multi-step purification process and operates endotoxin-free purification.
