WebExpression of heterologous proteins in E. coli often leads to the formation of protein aggregates known as inclusion bodies (IBs). Inclusion body aggregates pose a major hurdle in the recovery of bioactive proteins from E. coli. Usage of strong denaturing buffers for solubilization of bacterial IBs results in poor recovery of bioactive protein. WebJan 1, 2009 · For example, add 10 ml of solubilized protein in 6 M GuHCl at one time with rapid mixing to 590 ml of a suitable refolding buffer to achieve a 60-fold dilution. The protein concentration will be 16 μg/ml during the refolding, much lower than with reverse dilution and less likely to result in aggregation. 3. ims lowes login https://jeffstealey.com
