cDNA Library Protocols

The first libraries of complementary DNA (cDNA) clones were con­ structed in the mid—to—late 1970s using RNA—dependent DNA polymerase (reverse transcriptase) to convert poly A* mRNA into double—stranded cDNA suitable for insertion into prokaryotic vectors. Since then cDNA technology has become a fundamental tool for the molecular biologist and at the same time some very significant advances have occurred in the methods for con­ structing and screening cDNA libraries. It is not the aim of cD...
