Abstract
A method of detecting the level of transcriptionally-related gene expression from a population of cells includes the steps of isolating mRNA and DNA from a population of cells, quantifying the amount of a specific subpopulation of target mRNA transcribed from the target DNA and normalizing the amount of quantified target mRNA to target DNA for measuring transcriptional activity of the target DNA; a measure of gene expression per gene dosage.
Claims8
A method of determining the level of transcription of a specific gene comprising the steps of:
- (a) isolating mRNA from a population of microorganisms;
- (b) isolating DNA from the population of microorganisms;
- (c) quantifying the amount of a specific target mRNA in the isolated mRNA;
- (d) quantifying the amount of a specific target DNA in the isolated DNA, the specific target DNA being the DNA from which the target mRNA is transcribed;
- and
- (e) dividing the amount of target mRNA by the amount of target DNA to determine the level of transcription of the target DNA as a measure of specific gene expression per gene dosage.
A method of determining the level of transcription of a specific gene in response to a gene expression stimulus comprising the steps of:
- (a) adding a gene expression stimulus to the environment of a population of microorganisms:
- (b) isolating mRNA from the population of microorganisms;
- (c) isolating DNA from the population of microorganisms;
- (d) quantifying the amount of a specific target mRNA in the isolated mRNA;
- (e) quantifying the amount of a specific target DNA in the isolated DNA, the specific target DNA being the DNA from which the target mRNA is transcribed;
- (f) dividing the amount of target mRNA by the amount of target DNA to determine the level of transcription of the target DNA as a measure of specific gene expression per gene dosage in response to the gene expression stimulus;
- and
- (g) comparing the specific gene expression per gene dosage in response to the gene expression stimulus to the specific gene expression per gene dosage in the absence of the gene expression stimulus.
