1. A method for producing amplified amounts of nucleic acids from mRNA, said method comprising:
- (a) converting mRNA to ds cDNA with a first primer comprising an RNA polymerase promoter region and at least one priming site;
(b) asymmetrically amplifying said ds cDNA with a second captureable primer to produce an amplified amount of captureable antisense cDNA;
(c) capturing said captureable antisense cDNA; and
(d) converting said captured antisense cDNA to captured ds DNA.

Abstract
Methods of enzymatically producing unbiased amounts of nucleic acid from mRNA are provided. In the subject methods, a sample of mRNA is converted to ds cDNA using a primer containing an RNA polymerase site and at least one priming site. The resultant ds cDNA is then asymmetrically amplified with captureable primer to produce captureable cDNA which is then converted to captured ds cDNA. The resultant ds cDNA may then be used in a number of different applications, such as in the preparation of amplified amounts of aRNA, in the preparation of cDNA probes, and the like.
