For standard samples supply the Core Facilities with a mixture that contains 12 picomoles of primer, and templates at the concentration listed below, in a final volume of 12 µL in water. If using one of the ten supplied primers, provide listed amount of template in 6 µL water. This is double the amount of template and primer that we actually need so that we can rerun samples if there are any problems. We may reject samples if supplied otherwise. More information on primer concentrations below*
DO NOT ASSUME WE WILL DILUTE YOUR SAMPLES TO THE CORRECT CONCENTRATION.
We will run whatever you supply and assume you have diluted correctly.
Concentration of double-stranded template (in water) to supply Core Labs:
|PCR Product||Vector + Insert
Total DNA in
|Length||Total DNA in
|500 bp||25 ng||3 kb - 5 kb||400 ng|
|800 bp||50 ng||6 kb - 9 kb||600 ng|
|1000 bp||125 ng||10 kb - 15 kb||1 μg|
|2000 bp||250 ng||>15 kb||1.2 μg|
|3000 bp||350 ng|
*Please consult with Core Facilities staff about amounts of template and primer to use for BAC’s, YAC’s, PAC’s, cosmids, bacterial genomic DNA or M13 preps.
*For degenerate primers, add 12 picomoles primer per degeneracy, but do not exceed 100 picomoles.
If you have a primer in solution that is 100 micromolar, that is the same as 100 nmol/ml or 100 pmol/µl. We only need 12 picomoles in one sequencing reaction so dilute in the following method:
We supply the following primers:
|Forward Primer (M13F)

Our turnaround time is generally 2 days for 'standard' orders.
'Premium' orders are guaranteed a one-business day turn around time when both the order and samples are submitted for processing by 8:00am in the core facility. Drop samples off at Core Facilities, which is housed in the Agricultural and Life Sciences Building, Room 3012, Oregon State University. Samples go in the "To Do" boxes in the freezer and a web submission form must be submitted.
We are open for drop off from 8:00 am to 5:00 pm. Sample drop-off is in 3012 Agricultural and Life Sciences (ALS) Building.
Questions should be addressed to Katie Carter. Call (541)737-3413 for more information.
