Colonies from cDNA library on agar plateIsolate DNA from each clone, denature and bind to nylon membranesAdd total mRNA under hybridising conditions
Wash off unbound mRNA; single species is bound to each membraneElute bound mRNAUse mRNA to direct in vitro protein synthesisTest for production of desired protein by
procedures such as immunoprecipitation/electrophoresisFig. 6.29General principles involved in the technique of a hybrid select translation.228 Recombinant DNA and genetic analysis
