Are inclusion bodies the bane of your existence or a hidden opportunity? For researchers working with recombinant proteins in E. coli, finding your target protein in an insoluble pellet is a common frustration. But science shows these aggregates are specific, reversible, and often highly pure. This article dives into the mechanisms of protein aggregation, offers proven strategies to prevent it, and provides a step-by-step guide to solubilizing and refolding your protein for m

Is your Western Blot showing a band at the wrong molecular weight? This is one of the most common frustrations in the lab, but it's not a dead end. An unexpected band size is often a critical clue, not a failed experiment. The theoretical calculated weight from amino acid sequence rarely matches the observed weight on a gel. This discrepancy can be caused by a host of biological reasons from post-translational modifications like glycosylation to protein cleavage, splice varia
