Iptg induces tac production
WebSep 13, 2024 · The present invention provides a method for manufacturing an artificial polypeptide fiber, the method comprising: a step for bundling a plurality of raw material fibers containing an artificial polypeptide; and a step for bringing an obtained bundle of raw material fibers into contact with a composition containing a binder and an enzyme. WebThe culture is cooled down to room temperature. Protein production is induced by adding 100 mM IPTG to a final concentration of 0.4 mM and the culture is further incubated overnight at 18 °C with shaking. 4. Cells are harvested by centrifugation at 3500 × g for 30 min and the cell pellet is washed with 200 ml of 1× TBS.
