Quantifying cytokines on the protein level can be problematic because of low concentrations or degradation during sample handling. Aiming towards finding a simple method by which to quantify cytokines on the mRNA level, we combined existing and established molecular biology techniques. Based on the principle of quantitative competitive RT-PCR with a DNA-competitor, IL-1beta, IL-6, IL-12alpha and the housekeeping enzyme GAPDH are measured at levels down to 200 copies of mRNA.
