WebJul 27, 2024 · During in vitro renaturation, the high concentration of denaturant has to be removed to facilitate disulfide-bond formation and correct folding of proinsulin to its native form (Harrison et al. 2015). Dilution of the solubilized protein in refolding buffer is by far the most popular choice in insulin production.
WebProinsulin measurement is a useful adjunct for the diagnosis of insulinoma. Proinsulin is normally converted to insulin and C-peptide in the beta cells.
