β¦ Synopsis
An improved method for the rapid extraction and purification of the nucleic acids from small amounts of Escherichiu co/i is described. The method is applicable to multiple samples of about 5 X IO" cells each, and can be completed in about 4-6 hr. Recovery is on the order of 60%, there is little detectable degradation or selective loss of RNA, and virtually all of the cellular-derived carbon in the final preparation is nucleic acid. 34

Adsorption to Matrex Gel Green A and successive elution with uridine provides a one-step procedure for the purification of uridine phosphorylase from Escherichia coli B. The homogeneous preparation of the enzyme can be obtained within a single day with an activity recovery above 80%.
## Abstract Until now it has not been possible to obtain nuclear bodies from __Escherichia coli__ after treatment with rifampicin. It was generally assumed that the crossβconnections between the DNA double strands which are sensitive towards ribonuclease are destroyed under the influence of inhibit
