WebSchéma explicatif de l'opéron lactose. L' opéron lactose, ou opéron lac est un opéron nécessaire au transport et au métabolisme du lactose chez Escherichia coli, ainsi que d'autres bactéries de la flore intestinale. L'opéron lactose est composé de trois gènes structurels : lacZ, lacY et lacA. Il est régulé par plusieurs facteurs ... WebIPTG induction. IPTG Induction and Extraction of Proteins from Bacteria Prepared by Swathi Arur and Sudhir Nayak Induction in bacteria can be performed using one of two basic methods. Fast induction does not work for all proteins and can give you suboptimal yields. Slow induction can enhance the solubility of some proteins.

WebOne percent of the seed culture was inoculated into LB broth supplemented with 0.5 mg/ml L-arabinose, 20 μg/mL chloramphenicol and 50 μg/mL kanamycin until the OD 600 reached 0.35. At this point, cells were cooled to 4°C for 15 min and subsequently induced with 0.1 mM IPTG at 15°C for 24 h. WebMar 9, 2010 · Small-scale tests showed no difference in expression between induction with either IPTG (0.1, 0.5 and 1.0 mM) or lactose (0.5% w/v) using the pCOLD system, therefore the cheaper lactose was used for induction. All cultures were induced at an OD 600 ~0.5 and cultivated at 25°C for 20 h.
