Rapid synthesis of a protein that cannot reach its native state leaves partly folded chains with exposed hydrophobic surfaces, which associate and precipitate. For disulfide-containing proteins this is the rule rather than the exception in E. coli. Inclusion bodies are in one sense convenient: they are dense, relatively pure and protect the protein from proteases.
The 13-residue extension of LR3 was originally part of making this expression workable.
Dilution lowers protein concentration so that intramolecular folding outpaces intermolecular aggregation. The redox buffer sets a mild oxidising potential under which thiols pair, mispair and exchange until stable disulfides form. Temperature, pH, time and additives are optimised for each protein. Yield of native protein is typically a fraction of the input, and the balance is isomers and aggregates.
This step is where the swap isomer arises and is why it must be controlled downstream.
Purification by ion-exchange and reversed-phase chromatography, with the latter resolving the disulfide isomers; buffer exchange; and lyophilisation. The certificate reports the outcome. This page describes a manufacturing process in general terms.
