Additionally, Table 2 provides a quick reference for some of the popular strains, their genotypes, and their primary use in the lab. These strains are all based on E. Table 2: Lab strains of E. Note: Inactivating mutations in specific genes are signified with a minus sign - as is typically standard; just having the gene listed indicates it is non-functional.

However, recent advancement of biotechnology has shown substantial recovery of bioactive protein from such insoluble IBs by solubilization and refolding processes. In addition, gene fusion technology has also widely been used to improve the soluble protein production using E. This study demonstrates that mild-solubilization and in vitro refolding strategies, both are capable to recover soluble scFv protein from bacterial IBs, although the degree of success is greatly influenced by different fusion tags with the target protein.

It was observed that the most commonly used fusion tag, i. On the other hand, mild solubilization process potentially could recover soluble and functional scFv protein from non-classical IBs without assistance of any fusion tag and in vitro refolding step. The recovery yield achieved by mild solubilization process was also found higher than denaturation—refolding method except while scFv was refolded in fusion with MBP tag.

Concomitantly, it was also observed that the soluble protein achieved by mild solubilization process was better structured and functionally more active than the one achieved by in vitro refolding method in the absence of MBP tag or refolding enhancer. Maltose binding protein tagged scFv has shown better refolding and solubility yields as compare to mild solubilization process.

However, in terms of cost, time and tag free nature, mild solubilization method for scFv recovery from bacterial IBs is considerable for therapeutic application and further structural studies. The online version of this article In the recent time, antibody based biomolecules are being frequently used in disease diagnosis and prevention.

One of such widely used biomolecules is single chain variable fragment scFv antibody which is particularly attractive due to its smaller size, low immunogenicity and low cost production [ 1 ].

However, production of fully functional scFv antibody protein from bacteria is still challenging due to its misfolding and formation of inclusion bodies IBs [ 23 ].

Excess production of recombinant protein in the bacterial cytosol often triggers the partially folded proteins to interact with each other that results in protein aggregation thus IB formation [ 45 ]. The reducing environment of the bacterial cytoplasm also contributes to protein misfolding as well as IB formation by inhibiting intra-disulfide bond formation [ 6 ]. Generally, IBs are protein aggregates with very little or no biological activity [ 7 ]. Currently, with the aid of recombinant technology and protein engineering, several strategies such as gene fusion technology, co-production of chaperones and foldases, use of mutated host strains, lowering expression temperatures and inducer concentration have been exploited for efficient soluble protein production in E.

Now a days, denaturation and refolding of classical and non-classical IBs are becoming prevalent to recover soluble and active protein from E. In this study, gene fusion technology was applied along with denaturation—refolding process to recover soluble scFv protein from bacterial IBs. In addition, mild solubilization strategies have been verified as high yielding and cost effective in comparison to the complete denaturation and in vitro refolding technique [ 13 ].

To obtain bioactive protein, IBs are usually denatured with high concentration of chaotropes such as urea or guanidine hydrochloride GdnHCl [ 14 ]. High concentration of chaotropic agent results in complete denaturation of insoluble IBs which are further subjected to a single refolding step to recover soluble protein [ 16 ]. Several studies have mentioned earlier that the recovery yield of soluble protein from bacterial IBs depends on its nature and the strength of denaturing agents which are applied during the solubilization process [ 719 ].

Generally, in vitro refolding technology includes complete denaturation of classical IBs with high concentration of denaturing agents followed by dilution in refolding buffer and subsequent dialysis to remove excess salts and other denaturing agents [ 22021 ]. The major drawbacks of this method are its complex and expensive operational process which further needs extensive optimization at a number of steps [ 22 ]. In addition, use of high concentration of denaturing agent results in complete denaturation of secondary structure of IB protein leading to re-aggregation during successive refolding process [ 23 ].

Consequently, recovery yield of soluble protein is greatly reduced during the process of in vitro refolding. Currently, with the knowledge of genetic and protein engineering, novel tailored-made strategies have been applied to improve the soluble protein production from E.

Gene fusion is one such commonly used technology that has shown to improve the soluble protein production in bacteria [ 24 ]. A widely accepted study has shown that fusion of maltose binding protein MBP at the C-terminal of recombinant scFv greatly influences its soluble and functional expression in E. Another recent study has shown that MBP-scFv conjugates retain better in vitro solubility and stability as compared to untagged scFv [ 26 ].It saves a lot of time and money because we now do all our cloning in SnapGene first and catch any snags in the strategy before they hold us up.
