Quantification ofMALT1gene expression by real-time PCR. Logarithmic plot of fluorescence signal (y-axis) versus number of PCR cycles (x-axis). Samples D1, D2, D3, and D4 represent results obtained with RNA extracted from peripheral blood mononuclear cells from 4 healthy donor samples. MALT1 curves in duplicate for case 2 (red and green lines) and SSK-41 cell line (blue and yellow lines), all with similar MALT1 expression levels with respect to healthy donors, are shown.
