Inclusion body protein purification
WebEscherichia coli has been most widely used for production of the recombinant proteins. Over-expression of the recombinant proteins is the mainspring of the inclusion bodies formation. The refolding of these proteins into bioactive forms is cumbersome and partly time-consuming. WebInclusion bodies are found in bacteria as particles of aggregated protein. They have a higher density than many other cell components but are porous. [7] They typically represent sites of viral multiplication in a bacterium or a …
