A complete cDNA library is one that contains at least one cDNA clone representing each mRNA in the cell. A method is provided in this unit for calculating the required base of a cDNA library such that the library should contain at least one copy of every mRNA. Either a phage or plasmid vector can be used in constructing a complete cDNA library, and protocols are described for both. Procedures for evaluating these cDNA libraries are also provided along with a procedure for evaluating the quality of the λ arms used in constructing complete phage cDNA libraries.
