A process of refolding a recombinant protein from inclusion bodies (IBs) formed inside a host cell, is provided. The process includes homogenising a wet cells slurry to obtain a cell lysate incubating the cell lysate with a reducing agent to obtain a reduced cell lysate isolating reduced IBs from the reduced cell lysate to obtain isolated IBs solubilising the isolated IBs with a denaturing agent to obtain solubilised IBs and subjecting the solubilised IBs to a unit process of refolding to obtain a refolded recombinant protein.
