Glossary of Terms 256Lab-on-a-ChipLadderThe generic term for a microfluidic product, signifying a chemicalprocess or material movement taking place on a microchip. Incontrast to analysis in a standard laboratory that relies on humanintervention at several stages to manipulate or observe samplesand record results, the self-contained lab-on-a-chip represents analmost hands-free technology.A ladder well is located at the bottom right of the chip (after theladder has been loaded, this well also functions as a waste well).The ladder is analyzed first before sample analysis starts.The peak sizes and markers defined for the ladder in the assay areassigned consecutively, starting with the first peak detected in theladder. If too few peaks are detected in the ladder well, analysisstops and an error is generated. Peaks appearing above the uppermarker do not have to be detected. The Peak Table View for theladder well shows the peak size and concentration set in the AssayAnalysis Window.Figure 117.
