Recommendations
For best results, we suggest the following; (Also check our helpful hints page!!!!! )
- Prepare the template DNA and primer in DI water...Do not use TE.
- Primer must be at least 18-24 bp with a melting point temperature of 50oC higher.
- The primer must be at a concentration of 3.2-10 pmol/ul.
- Indicate type of DNA template being sequenced; ds, ss, or pcr DNA (include size)
- For each reaction: 50-100 ng ssDNA, 0.5-1.0 ug cosmid DNA
0.5-1.0 ug dsDNA, 1-2 ug BAC, 2-3 ug bacterial genomic DNA - For successful direct genomic sequencing we strongly recommend a high quality genomic prep.
- For recommended DNA isolation methods please contact us for details at This email address is being protected from spambots. You need JavaScript enabled to view it. . We recommend Mo Bio Laboratories for DNA isolation kits for the ease and quality of the preps as well as the low cost per sample.
- Carefully check all templates for proper concentration and purity... LOW TEMPLATE CONCENTRATION, SALT,and or ALCOHOL contamination in preps will result in failure of sequencing reaction !!!
- For sequencing a PCR and DS product:
- 100-200 bp 10-20 ng/rxn
200-500 bp 20-40 ng/rxn
500-1000 bp 30-80 ng/rxn
1000-2000 bp 50-100 ng/rxn
>2000 bp 100-200 ng/rxn
single-stranded 50-100 ng/rxn
double-stranded 200-500 ng/rxn
cosmid, BAC 0.5-1.0 ug/rxn
bacterial genomic DNA 2-3 ug/rxn - Adjust to a final volume of 10ul and label tubes w/ DNA concentration and date.
- Note: It is the responsibility of our clients to check all electrophoregram for:
- mis-calls
- spacing
- we do not edit any of the sequence
