Paenarthrobacter aurescens | expression induction with 0.4 mM IPTG at 25°C for 5 h is the best condition for the expression of soluble TreS, higher temperature or IPTG concentrations lead to a higher rate of inclusion bodies, whereas a temperature below 20°C and lower IPTG concentrations decreases the total amount of TreS | up |
