Purifying natively folded proteins from inclusion bodies using sarkosyl, Triton X-100, and CHAPS.

چکیده
We describe a rapid, simple, and efficient method for recovering glutathione S-transferase (GST)- and His6-tagged maltose binding protein (MBP) fusion proteins from inclusion bodies. Incubation of inclusion bodies with 10% sarkosyl effectively solubilized >95% of proteins, while high-yield recovery of sarkosyl-solubilized fusion proteins was obtained with a specific ratio of Triton X-100 and CHAPS. We demonstrate for the first time that this combination of three detergents significantly improves binding efficiency of GST and GST fusion proteins to gluthathione (GSH) Sepharose.

Optimizing Primary Recovery and Refolding of Human Interferon-b from Escherichia coli Inclusion Bodies
Background: The refolding of proteins from inclusion bodies is affected by several factors, including solubilization of inclusion bodies by denaturants, removal of the denaturant, and assistance of refolding by small molecule additives. Objectives: The purpose of this study was optimization of recombinant human interferon-b purification in order to achieve higher efficiency, yield, and a produ...
متن کاملImproved recovery of active GST-fusion proteins from insoluble aggregates: solubilization and purification conditions using PKM2 and HtrA2 as model proteins.
The glutathione S-transferase (GST) system is useful for increasing protein solubility and purifying soluble GST fusion proteins. However, purifying half of the GST fusion proteins is still difficult, because they are virtually insoluble under non-denaturing conditions. To optimize a simple and rapid purification condition for GST-pyruvate kinase muscle 2 (GST-PKM2) protein, we used 1% sarkosyl...

Recently, we found that sphingomyelin bound and activated hepatitis C virus (HCV) 1b RNA polymerase (RdRp), thereby recruiting the HCV replication complex into lipid raft structures. Detergents are commonly used for resolving lipids and purifying proteins, including HCV RdRp. Here, we tested the effect of detergents on HCV RdRp activity in vitro and found that non-ionic (Triton X-100, NP-40, Tw...

The effect of Triton X-100, Na cholate and Tween 80 on the solubilization of integral membrane proteins in intact cells, spheroplasts and inner-membrane fragments of Salmonella typhimurium was studied. The detergents were used in various concentrations (1.6 to 64 mM) and cytochromes b and d were used as marker to monitor the solubilization of membrane-bound proteins. Results showed that no inne...
متن کاملRefolding Process of Cysteine-Rich Proteins: Chitinase as a Model
Background: Recombinant proteins overexpressed in E. coli are usually deposited in inclusion bodies. Cysteines in the protein contribute to this process. Inter- and intra- molecular disulfide bonds in chitinase, a cysteine-rich protein, cause aggregation when the recombinant protein is overexpressed in E. coli. Hence, aggregated proteins should be solubilized and allowed to refold to obtain nat...
