Monday June 22, 2020 update:

As Stanford enters Stage 2 research restart, SUMS' goal is to safely support research projects while adhering to physical distancing rules.  Processes for the most part will remain the same, with samples being dropped off for analysis and meetings and interactions continuing via Zoom.  Contact us via email at, or join our SUMS workspace on Slack and message us at #contact-sums.


Monday June 1, 2020 update:

As the purpose of Stage 1 research restart is to prepare the labs for an increase in research activities in Stage 2, SUMS is using this time to bring instruments back online and into proper operational condition.  Some instruments may be ready before others, and we will post status updates on this webpage.  Our goal is to safely support researchers' projects as they restart.

Please do feel free to submit iLab request(s) now, to help us gauge demand for the various SUMS instruments/capabilities.  It will be helpful for planning purposes to include a comment on the estimated length of time you would need between when we let you know we're ready to run samples and when your samples could arrive at the lab.

Note that the open access lab will also be operated on a drop-off model, at least for the initial stages of research restart.  There will be no fee changes nor additional charges for this service.  For open access planning, please send an email to with the following information:

  1. Open access instruments you will need samples run on
  2. Estimated number of samples/batch (for each instrument in #1)
  3. Projected frequency of batches (e.g. once a week)
For all users, there are 3 items that need to be completed before coming to drop off samples at SUMS.  The first two are Stanford-wide requirements; the third is specific to SUMS:
  1. Complete EHS-2470-WEB, "COVID-19 Hygiene Best Practices" in STARS
  2. Use the Stanford Health Check tool to self-report health status prior to coming on site to campus each day
  3. Review and complete the SUMS Staff/User Agreement - COVID Addendum

You will also need a Stanford Slack account (get started at to connect with the SUMS #sample-drop-off channel. 
Meetings and interactions other than sample drop-off will continue to be held remotely, typically via Zoom.  Please email if you have any questions or concerns



Tuesday May 19, 2020 update:

SUMS is currently able to support essential approved research projects; please contact us at to discuss and make arrangements.

For other projects, please continue getting in touch with SUMS via the email.  Ideally project discussions and planning will be completed ahead of time, so that we all can hit the ground running when restrictions are eased.

As you will be experiencing in your own labs, operations will be quite different under physical distancing.  Initially, the only in-person interactions will be for transferring samples to SUMS; SOPs will be provided.  When the open access lab reopens, it will be operated under a drop-off model for at least the initial stages of the campus research restart.  There will be no fee changes nor additional charges for this service.

Dear SUMS User,
In line with guidance from the University and consistent with the shelter in place order here in the Bay Area, Stanford University Mass Spectrometry will be entering a period of research shutdown effective March 17th. As a result, we will not be able to receive samples and the open access lab will be closed for the remainder of this period, currently estimated to continue through April 7th. As the COVID-19 situation is fluid, we would direct you to our website – – to find up-to-date information as our research operations come back online.
If you have recently delivered samples, or if you are waiting on research data, we are either 1) completing tasks remotely to deliver the data to you per our usual process, or 2) pausing the experiment in a safe way if samples have not yet been analyzed on our mass spectrometry instruments. If you would like more details regarding ongoing sample status, please contact us at with the iLab number in question, and we will provide further details specific to your project.
SUMS staff will still be available for research consultation, project planning, and other customized support via Zoom. If you’d like to speak with our team, please email your inquiries to and we will set up a time to meet. Also note that we will be continuing our seminar series via Zoom in the interim – our next event is this Thursday – so please see for details on upcoming events.
Thank you for your patience as we all navigate this complex new territory together. SUMS looks forward to supporting your research fully as soon as we are all able to return to full capacity.
Best Regards,
Allis Chien
SUMS Director

SUMS Director of Proteomics
