Fragment analysis service

We will add the size standard of your choosing and perform electrophoresis on the samples..

Before pooling multiplex PCR products

  • We recommend running a mini-gel to verify that your PCR product works.
  • Determine optimal PCR concentration by serial dilution.
  • Example of possible microsatellite optimized concentration: pre-PCR = 50 ng/µl, post amplification 25 ng/µl
  • To avoid Plus A problem, order primer with tails. See User Bulletin: Plus A Artifacts for more information.

Rates

The minimum number of samples for a fragment analysis submission is 24 samples. You may submit fewer, but you will still be charged for 24 wells.

If samples are submitted in an incorrect plate type, the user will be charged a re-plate fee.

Submission protocols

  • Yale users: 1-2 µl of each fluorescently labeled PCR product brought to a final volume of 10 µl with water or HiDi formamide.
  • External users: 1-2 µl of each fluorescently labeled PCR product brought to a final volume of 10 µl with water. 

We will add the size standard of your choosing to your submission.

All samples must be submitted in a (non-fully-skirted) 96-well optical plate with clear 2 mL wells. For thicker plastic plates, the angled corner must be in A12. (See the Plasticware specifications page.)

Please fill your plate by column; i.e: A1-H1, A2-H2, and so on. 

You may fill out the Sample Sheet Template form if you wish to have specific names for your samples.

It must be sealed properly with strip caps or sealing film to avoid spillage/cross-contamination. If using stop caps, we recommend wrapping the plate with parafilm.

The submission is light sensitive, and should be wrapped in aluminum foil.

If you are shipping your samples, be sure to protect your wells with packing paper, bubble wrap, plate holders, etc. to avoid any breakage.
