Basicproceduresforbacteriaculture1

A. Phenol extraction of DNA samplesPhenol extraction is a common technique used to purify a DNA sample (1). Typically, an equal volume of TE-saturated phenol is added to an aqueous DNA sample in a microcentrifuge tube. The mixture is vigorously vortexed, and then centrifuged to enact phase separation. The upper, aqueous layer carefully is removed to a new tube, avoiding the phenol interface and then is subjected to t......阅读全文
