WebAfter optimization of viral MOI and shRNA sequence used, an induction curve was performed for each target using varied concentrations of IPTG or DOX, as indicated. Induction of shRNA expression was carried out for 48 hours, after which total RNA was harvested from the treated cells and target expression was measured by qRT-PCR.
WebNov 30, 2016 · The majority of bacterial expression systems use isopropyl beta-thiogalactopyranoside (IPTG) for induction. The key to this is when and how much. Induction can be done at early (OD = 0.2-0.4), middle (OD = 0.6), or late (OD = 0.8-1.0) phases and IPTG concentrations can be varied from 0.1 – 1.0 mM using a concentrated stock. WebThis protocol describes the preparation of a Isopropyl β-D-1-thiogalactopyranoside (IPTG) stock solution at various concentrations.. A typical stock solution concentration is 100mM IPTG..
