Miniprep refrigerated bacteria
WebNope, you can miniprep modest sized colonies from plates. Turbid cultures are good enough, in fact saturated cultures produce DNA with more endotoxins. The longer they are in stationary phase the more endotoxins they produce and they stop making more plasmid. WebSmall-scale plasmid isolation, called plasmid miniprep, requires a small amount of bacterial culture. Normally, a 2 – 5 ml culture provides sufficient cells that can be processed for …
