20 Page 20 2008 qPCR - Why Quality Matters Sample/template quality RNA quality control (Quality of template):  RNA degrades naturally due to enzymatic or autocatalytic mechanisms:  Any 5’ or 3’ biased design might fail or produce misleading results  Wrong priming strategy in the RT step can produce misleading results  Knowing RNA quality allows to accommodate the amplicon design and set expectations avoiding wrong interpretatio of results  All quantifications rely on comparable template quality to be meaningful

21 Page 21 2008 qPCR - Why Quality Matters Sample/template quality Quality of assay Robust and meaningful results QPCR assay validation/optimization (Quality of results):  The resolution of SYBR Green meltcurves is limited  T m depends on dye/template ratio  SYBR Green is a non-saturating dye  Verifying the size of PCR products is a recommended validation procedure:  Resolution of slab gels limited!

61 Page 61 2008 Principle of Pressure-Driven Flow For cell assays (analysis of cell fluorescence parameters) On-chip simple flow cytometric studies Pressure driven flow is used to move cells in a controlled manner through the micro- channels Cells are hydrodynamica lly focused to a portion of the channel by a side stream of buffer Cells pass the fluo-rescence detector in single file and each event is monitored in a histogram or dot plot The micro- channels of the glass chip are filled with cell buffer

62 Page 62 2008 The Bioanalyzer Lab-on-a-Chip Approach Separation on disposable, µ-fabricated glass chips made of two glass layers: one with micro-channels (x10µm, etched), one with through-holes glued into a plastic caddy which accommodates wells for gel, sample, standard (ladder), buffer and other reagents for handling nl-amounts of liquids one separation channel for ladder and sample microfluidic sample movement with fluorescence detection Setup micro-channels are filled with gel or buffer sample, ladder and reagents are filled into the respective wells chip preparation in less than 5 minutes Benefits convenient handling minimized risk of cross-contamination versatile design for multiple experiments on one platform

63 Page 63 2008 Flow Cytometry on a Chip - Hydrodynamic Focusing All six cell samples are hydrodynamicly focused to one side of the micro channel At each of the six pinch points the cell stream is joined by a buffer stream from one of the two buffer wells The two liquids do not mix immediately The cells then move towards the detector in single file
