Inclusion body purification
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 ... Webthe inclusion bodies due to differences in size and density compared to some contaminants, (3) low degradation of the expressed protein due to the inclusion body’s resistance to proteolysis, (4) high homogeneity of the protein of interest in the whole lysate before purification, which helps in reducing
