The poster featured in this blog provides background information and data on development of Rapid Digestion-Trypsin.
Improvements in Protein Bioprocessing
As more and more protein-based therapeutics enter research pipelines, more efficient protocols are needed for characterization of protein structure and function, as well as means of quantitation. One main step in this pipeline, proteolysis of these proteins into peptides, presents a bottleneck and can require optimization of multiple steps including reduction, alkylation and digestion time.
We have developed a new trypsin reagent, Rapid Digestion–Trypsin, that streamlines the protein sample preparation process, reducing the time to achieve proteolysis to about 1 hour, a remarkable improvement over existing overnight sample preparation times.
How Does it Work?
With this new trypsin product, proteolysis is performed at 70°C, incorporating both denaturation and rapid digestion. The protocol can be used with multiple protein types, including pure proteins and complex mixtures, and is compatible with digestion under native, reduced or nonreduced conditions.
My former research career was spent in academic laboratories, and I don’t have first-hand experience in the world of bioprocessing. However in my current job as a science writer/copy editor, I create product information and literature about products that are useful to bioprocessing engineers and technicians, and thus wanted to learn more about this diverse area, where discovery and processing of biomaterials results in better therapeutic drugs, better biofuels and even healthier foods.
Bioprocessing is a combination of biological science and chemistry, and a burgeoning science field. Burgeoning is an understatement. Exploding is a much more apt description.
This 2011 Science magazine careers article defines bioprocessing thusly:
“Bioprocessing is an expanding field encompassing any process that uses living cells or their components (e.g., bacteria, enzymes, or chloroplasts) to obtain desired products, such as biofuels and therapeutics.”
