Measuring mRNA expression is fundamental to placental research. Ideally, mRNA transcript numbers are directly quantified. However, PCR analysis using the ΔΔCT method relies on the stability of housekeeping genes and only reports relative expression. Digital PCR (dPCR) directly quantifies mRNA copy number and is more accurate than quantitative PCR. We quantified absolute mRNA copy number of housekeeping genes in normotensive pre-term (n = 20), severe preeclamptic (n = 11) and term (n = 12) placenta using dPCR. Whilst there was some variation, we confirm absolute mRNA copy number of GAPDH, TOP1, CYC1 and YWHAZ in placenta does not significantly alter between these cohorts, or across gestation.
