WebProcess the culture supernatant/cell pellet/inclusion body, followed by extensive processing of the supernatant/cell pellet/inclusion body or diafiltration to extract or refold raw protein bulk. WebInclusion bodies are insoluble protein aggregates usually found in recombi-nant bacteria when they are forced to produce heterologous protein species. These particles are formed by polypeptides that cross-interact through sterospecific contacts and that are steadily deposited in either the cell’s cytoplasm or the periplasm.
WebBioRad protein assay was used to analyze the concentrations and yields of proteins. Our results show that 500 mL of bacteria have 41.3 ± 1.2 mg of total proteins, including 28.4 ± 1 mg of inclusion body, and 1.61 ± 0.09 mg of His-LfcinB could be purified, accounting for 3.9% of the total protein and 5.6% of the total inclusion body. WebInclusion bodies are insoluble protein aggregates usually found in recombinant bacteria when they are forced to produce heterologous protein species. These particles are formed by polypeptides that cross-interact through sterospecific contacts and that are steadily deposited in either the cell's cytoplasm or the periplasm.
WebExpression as inclusion bodies can allow expression of proteins that are toxic to the host cell. Optimizing for soluble expression The reasons for inclusion body formation are not well understood. However, it is well known that a reduced growth rate usually leads to more soluble expression and hence reduces the tendency to form inclusion bodies.
