Expression of proteins in bacterial host cells, particularly E.coli, has gained much attention in recent years. Low expression outcome is the main tech. drawback associated with this procedure, further restricting its largescale application in industry. Therefore, application of new amendments or reformations are required before further proceedings. Extremely low frequency magnetic fields (ELF-MFs) have shown to significantly affect biol. processes, including gene expression, in E.coli. In current study, we investigated whether application of ELF-MF could result in overexpression of proteins in E.coli or not. Cluster of differentiation-22 (CD22), as a model protein, was expressed in E. Coli Rosetta (DE3) under continuous exposure to ELF-MF after applying various concentrations of Iso-Pr ss-D-1-thiogalactopyranoside (IPTG) (0.25-1.25 mM) as inducer. The strength and frequency of electromagnetic fields (EMFs) ranged between 15 and 100 mT and 2.5-20 Hz resp. Interestingly, application of 55 mT EMFs with frequencies ranging from 2.5 to 2.8 Hz significantly enhanced the yield of expression at all studied IPTG concentrations Contrarily, EMFs with intensities other than 55 mT meaningfully declined protein expression at IPTG concentrations equal to 1 and 1.25 mM. In conclusion, application of specific range of ELF-MFs may be exploited as a new modification for enhancing heterologous expression of proteins in E.coli. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Safety of (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol).
(2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Safety of (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol
