Abstract | A non-radioactive multiple reverse transcription-PCR method for the relative quantitative analysis of low abundance mRNA is described. Chemiluminescent detection of cDNA products amplified by PCR and incorporating biotin-labelled dCTP was used for analysis of specific gene expression. After determining the optimal concentrations of RNA and cDNA, the tube-to-tube variations were minimised by transcription and amplification of the endogenous standard mRNA coding for protease C from Aspergillus niger, together with the transcript of interest. All the obtained data were relative values comparing to the internal standard pepC. By the method the difference in mRNA level between the two transformants with different pkaC gene copy number coding for cAMP-dependent protein kinase (PKA) catalytic subunit from A. niger was detected which was in accordance with the diferences in specific PKA enzymatic activity between both strains. | |
