For the 0.5 mm wide micro capillary electrophoresis chip, 0.33 μL of a 5μM solution (concentration was previously determined by oligonucleotide synthesis center, University of Wisconsin Biotechnology Center) was delivered into the separation channel. Using dimensional analysis and given the MW of this particular oligonucleotide was 31185μg/mol:(0.33 x 10-6 L) x (5 x 10-6 mol/1 x 10-6 L) x (31185μg/mol)= 0.514 μg or 51.4 ngThe calculation shows 51.4 ng of DNA was injected into the device. The sample was extracted from the device using passive pumping and was placed in a 100μL drop and analyzed in a Biotek HT fluorescent plate reader. The reading obtained was 45. Using the fit equation above, the concentration of extracted oligonucleotide in the 100μl drop was 0.0137 μM. Once again using dimensional analysis:
