Inclusion body purification
WebInclusion bodies are formed from partially folded protein intermediates and are composed of aggregates of mostly single types of polypeptide. This helps to isolate and purify the protein aggregates to homogeneity before solubilization and refolding. Proteins inside inclusion body aggregates have native-like secondary structures. WebJan 28, 2024 · The process involves four major steps, namely, (1) isolation of IBs (2) solubilization of IBs, (3) refolding of solubilized protein, and (4) purification of refolded protein. Bacterial cells are induced to overexpress gene of interest into inclusion bodies inside of the cell. Inclusion bodies are then isolated by breaking open the bacterial ...
