Transcriptional profiling, which is directly or indirectly associated with expressed protein levels, has been used in various applications including clinical prognosis and pharmaceutical investigation of drug activities. Although the widely used reverse transcription polymerase chain reaction (RT-PCR) allows for the quantification of absolute amounts of mRNA (mRNA) from inputs as small as a sin...
BACKGROUND BCR-ABL fusion mRNA expression in bone marrow or peripheral blood can be used as a measure of minimal residual disease in patients with chronic myeloid leukemia (CML). METHODS We used an oligo(dT)-coated manifold support to capture the mRNA directly from the cell lysate. After reverse transcription, the cDNA was eluted from the manifold support, and BCR-ABL and GAPDH mRNAs were qua...
In situ hybridization analysis of tissue mRNA concentrations remains to be accepted as a quantitative technique, even though exposure of tissue sections to photographic emulsion is equivalent to Northern blot analysis. Because of the biological importance of in situ quantification of RNA sequences within a morphological context, we evaluated the quantitative aspects of this technique. In calibr...
We previously conducted basic research to quantify in situ hybridization (ISH) signals in rat testes. In this experimental model, we selected ribosomal RNA (rRNA) as the hybridizable RNA in paraffin sections, since it allowed us to easily analyze ISH signals expressed with digoxygenin (DIG)-labeled probes quantitatively through "posterization" of the images. We applied this method to analyze th...
