What can I do to improve the sensitivity of my qPCR assay?
If you are targeting a low-abundance gene, you may have trouble getting Ct values in a good, reliable range (Ct > 32). To increase the sensitivity of the assay, you may want to consider the following:
- Increase the amount of RNA input into your reverse transcription reaction, if possible
- Increase the amount of cDNA in your qPCR reaction (20% by volume max)
- Try a different reverse transcription kit, such as our SuperScript VILO Master Mix, for the highest cDNA yield possible
- Consider trying a one-step or Cells-to-CT type workflow (depending on your sample type)
Single cell gene expression analysis of pluripotent stem cells.
Authors:Abruzzese RV, Fekete RA,
Journal:Methods Mol Biol
PubMed ID:23546759
Analyzing gene expression profiles from cells en masse provides an average profile for the population which may obscure differences in individual cells. Using an optimized workflow for qRT-PCR, gene expression profiles of undifferentiated pluripotent stem cells reveal distinct gene expression profiles for individual cells, and a large expression level range ...

Toll-like receptor 4 engagement drives differentiation of human and murine dendritic cells from a pro- into an anti-inflammatory mode.
The dendritic cell (DC) coordinates innate and adaptive immunity to fight infections and cancer. Our observations reveal that DCs exposed to the microbial danger signal lipopolysaccharide (LPS) in the presence of interferon-? (IFN-?) acquire a continuously changing activation/maturation phenotype. The DCs' initial mode of action is pro-inflammatory via up-regulation among ... More
Interleukin-10 inhibits angiotensin II-induced decrease in neuronal potassium current.
Authors:Jiang N, Shi P, Desland F, Kitchen-Pareja MC, Sumners C,
Journal:Am J Physiol Cell Physiol
PubMed ID:23426971
Previously we demonstrated that viral-mediated increased expression of the anti-inflammatory cytokine interleukin-10 within the paraventricular nucleus of the hypothalamus significantly reduces blood pressure in normal rats made hypertensive by infusion of angiotensin II. However, the exact cellular locus of this interleukin-10 action within the paraventricular nucleus is unknown. In the ... More
