2. High Throughput DNA Sequencing Beckman CEQ 2000XL DNA Analysis System

3. Beckman CEQ 2000XL DNA Analysis System This is an automated unit capable of reading and analyzing DNA sequencing products that have been generated by incorporating WellRED fluorescent dyes into the DNA. The dyes fluoresce and are automatically detected and processed by the system’s software. The system is equipped with an array made up of eight parallel capillaries permitting electrokinetic injections of eight samples at a time. This high throughput setup allows for 96 samples to be processed and analyzed by the system's software in 24 hours. On average, sequences of 600 to 850 bases per sample can be generated, depending on primer and template qualities.

6. Guidelines for DNA Sample Preparation ***REMEMBER: HIGH QUALITY TEMPLATE WILL LEAD TO HIGH QUALITY DATA!!!! IT IS TO YOUR ADVANTAGE TO FOLLOW PROCEDURE!!!! Prepare templates properly: Resuspend in water or Tris-HCl. Do not resuspend in TE or EDTA reagents. Must be purified and free of ionic contaminants Best to use a commercial kit for purification! The Qiagen Qiawell and Qiaprep work well (dsDNA and ssDNA) Standard Alkaline Lysis Preps (NO PHENOL!!!) For PCR Products: Qiagen QIAquick PCR purification kit PCR products must be homogeneous Quantitate DNA: Spectrophotometeric Fluorometeric Agarose Gel Custom Primer Considerations: Quality primers necessary Purified by desalting, HPLC or OPC purification preferred Size around 20 bases with 18 bases as a minimum GC content should be less that 50% Avoid primer dimerization Ratio for dsDNA is greater than 40:1 primer:template molar ratio (~3.2 ρmol).
