Penn State chemical engineers have demonstrated proof of concept for a new protein purification process that combines ultrafiltration's high throughput with high specificity achievable through ...

Effective and efficient protein purification processes are essential in drug discovery and development. Affinity fusion tags ...

For the novice protein purifier, finding a place to start might seem overwhelming, but fortunately the process can be approached systematically. Andrew Mitchell, technical consultant for Amersham ...

Depending on the process and who provides the statistics, downstream processing accounts for between 50–80% of the cost of producing biotech drugs. Whatever the exact number, protein purification ...

Engineers devised a way to purify protein drugs during manufacturing. Their approach, which uses nanoparticles to rapidly crystallize proteins, could help make protein drugs more affordable and ...

Most researchers know they need a pure protein. Few talk about how genuinely difficult it is to get one. A cell lysate contains thousands of proteins competing for the same space. Your target is in ...

Self-removing tags can be used for simple and effective purification of recombinant proteins and peptides. The key component of these tags is an intein, which is a protein element with the ability to ...

So long as living cells serve as tiny drug-making factories, they will, like much larger factories, generate unwanted byproducts. As industrial byproducts go, the cells’ byproducts, which are known as ...
