Can I pause a bacterial culture at 4°C

22 January 2013 - 06:39 AM

Hi evryone,

I'm doing a 5ml liquid culture of DH5 E.coli transformed with an ampicillin resistance plasmid. I'd like to have a culture that  grew 12 to 16h in LB before doing the miniprep but that is really not fitting well my planning. I was wondering if it's OK to pause the culture by placing the tube at 4°C and then replace them at 37°C ?
WIll this step have any consequence on the bacterial growth or the plasmid expression?

Thanks in advance for your answers!

Sabrina
