We collect samples at 11:30 am 6:30 pm at the following locations:


  • By Mail: send your samples and order form overnight or second day air (no ice) to: 

             UC Berkeley DNA Sequencing Facility
             310 Barker Hall #3202
             Berkeley, California 94720-3202

             Place samples in a secondary container such as a 50 mL falcon tube to prevent crushing during shipping.


Turnaround Time:

  • You should receive your results via e-mail by the following business day if not sooner.  
  • Early bird catches the worm:  The results of the first three plates of the day are e-mailed by 7PM on the same day.
  • Please let us know right away if you do not receive your results by the expected date.


Accounting Information:

  • For UC Berkeley accounts: We need your chartstring (e.g. 1-56620-19900-22233-44-none-FN248) or a 10 digit "speed-type" reference to your chartstring. You can use the Chart of Accounts Validation Web Service to check that your on-campus accounting information is current. If it is not, contact your lab manager, your accounting department or your PI.
  • For other UC-system accounts: Use the accounting information you would normally use for any on-campus charge. Labs from CHORI and LBNL are charged the on-campus rate plus the cost of billing (10%) and should have a current purchase order number or IUT number.  Outside labs are charged 58% surcharge and should generate a purchase order and attach it to their order form or send a check with your samples made out to "UC Regents".
  • Call us if you have any questions  (510) 642-9601


How to view my chromatogram files:
