Primer Concentration

Concentration of Template and Primer

Supply the Core Labs 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.

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
Length Total DNA in
Final Volume
Length Total DNA in
Final Volume
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 Labs 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.
