描述 | The uptake of IPTG by E. coli is notable for its independence from lactose permease at higher concentrations, suggesting the involvement of alternative transport mechanisms. While low concentrations of IPTG utilize lactose permease for cellular entry, higher concentrations used for protein induction allow IPTG to enter cells without relying on this specific permease[1]. |

溶解方案 |
DMSO: 60 mg/mL(251.78 mM),注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO H2O: 100 mg/mL(419.64 mM),配合低频超声助溶 以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂: ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
