Although qRT-PCR studies provide valuable information about the relative expression of transcripts in a cell, they are difficult to perform with very small numbers of cells (for example, 1–1,000 cells ...

Libraries of cDNA clones are valuable resources for analyzing the expression, structure and regulation of genes, and for studying protein functions and interactions. Full-length cDNA clones provide ...

In a unanimous decision last month, the Supreme Court ruled that naturally occurring genes are not patentable. But, said the Court, cDNA, a man-made copy of the genetic messenger in cells, is ...
