Run 2-5 µl of sample + 2-5 µl of glycerol load buffer on a 0.8-2% agarose gel.

Load 5 µl of 0.1µg/ml DNA ladder. Use either 100-bp or 1-kb DNA ladder size as appropriate.

Ladders commonly used in lab.

Estimate band concentrations by eye or by saving the image in TIFF format and finding band densities with [[http://rsbweb.nih.gov/ij/][ImageJ]]. Compare to a reference band of similar density and determine the concentration of the original sample.

---+++ DNA purification

Use illustra™ GFX™ PCR DNA and Gel Band purification kit or Qiagen kit or similar reagent. Be sure to elute in buffer compatible with DNA sequencing applications. (Buffer 6 for the GE kit, or ddH<sub>2</sub>O)

For all practical purposes assume 90% recovery of the input DNA sample as long as it is >200 bp in length. Smaller fragments are not bound as efficiently by the column.

---+++ Sequencing Reaction

Normal submissions to RTSF at MSU should be in 96-well plates.
