Downstream sample preparation for subsequent quality attribute analysis represents “a significant bottleneck in process development for non-antibody biologics,” wrote Kevin Brower, PhD, global head of ...

Bed-height Optimization Can Reduce Cost and Increase Speed of Production Affinity chromatography is potentially the most selective method for protein purification and is often included as a primary ...

Tedious, time-consuming, exasperating: Those are perhaps the three words that researchers use most commonly to describe protein purification. Proteins, and their little sisters the peptides, are among ...

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 ...
