cDNA library


cDNA li·brar·y

a collection of copy (cDNA) fragments that have been made by reverse transcriptase from the mRNA of a particular cell, organ, or organism.

cDNA library

a collection of cDNA CLONES representing the RNA molecules present in a particular preparation obtained from a given CELL or TISSUE TYPE. Where the library is from a particular cell type it will be representative only of a selection of the total GENES present, because only some of those genes will be expressed to produce mRNA. see CDNA. Compare GENE BANK.
