<p>A method for assaying heterogeneous nuclear ribonucleoprotein B1 (hnRNP B1) mRNA present in a sample, the method comprising a step of using a first primer homologous to at least a portion downstream from the 5'-end of a specified nucleotide sequence of the RNA and a second primer complementary to at least a portion upstream from the 3'-end of the specified nucleotide sequence to produce double-stranded DNA containing the promoter sequence and the specified nucleotide sequence downstream from the promoter sequence, wherein at least one of the first and second primers has a promoter sequence at the 5'-end, a step of using the double-stranded DNA as template to produce an RNA transcript, a step of using the RNA transcript in turn as template for DNA synthesis to produce the double-stranded DNA, a step of nucleic acid amplification in which the aforementioned steps are repeated under conditions that simultaneously promote each of the steps, and a step of assaying the amount of the RNA transcript.</p> |
