Please email memc [a] with the assistance request, pending staff availability, your session will either be confirmed or rescheduled.

MEMC Workshops

It is usually held on the first Tuesday of the month from 9:30am to 12pm. Please email memc [a] for availability.

Screening Microscopes/Plunge Freezers

After-hours – or 24 hour – access, is given on a per instrument basis. This means for any instrument you want to book, you must be deemed independent on it by two separate MEMC staff members. To be independent, you must know how to properly start up, operate and shut down the instrument on your own. MEMC reserves the right to revoke ‘independence’ if we believe it is in the best course of action to prevent damage to instrumentation.

You may bring a guest to your session as long as they are a registered user at the center. If not, guests must be announced ahead of time by emailing memc [a] and must follow the visitor policy. More information about the guest/visitor policy can be found here.

Yes. First, we would recommend obtaining all the necessary consumables (gold wire and grids). Then, we can schedule a time to assist you with turning standard carbon foil on metal grids to gold foil on metal grids. Please email memc [a] once you have these consumables. Lastly, we used gold wire from Ted Pella which you can find here.

Krios Sessions

Please email memc [at] to schedule a grid drop off appointment. Note, if you are dropping off unclipped grids, they are due at the center no later than Wednesday 4:00pm, the week before the scheduled session. If you are dropping off clipped grids, they are due at the center no later than Friday 4:00pm, the week before your scheduled session. We encourage you to drop off grids well before the cut-off time and we accept grids up to 5 weeks ahead of your session. To open the Krios Grid Drop-off Checklist,  click here.

Grids are kept in our saved puck inventory for 2 weeks after a session, after that they are warmed up and discarded.

Any interested user should email memc [a] and their institutional representative an application. They must state that they are applying for rapid access time and submit an application. The application should include: a) Leginon project ID (if you do not have one please create one), b) Leginon IDs of the personnel that will be using the instrumentation, and c) a brief update of the progress of the project including why it is ready for the Krios (please include preliminary cryo data). Also, we prefer users to store their grids on site. If you receive time on another instrument you may always retrieve your grids during business days 10am-4pm. More information on rapid access can be found here.

Yes. The grids can be swapped out for new grids or new grids can be added to the ones already dropped off. If they are unclipped, they must be dropped off by Wednesday at 4 pm the week before your session. If they are clipped, they can be dropped off by Friday at 4pm the week before your session.  A new Krios Grid Drop-Off Form must accompany the grids.

We use Globus for data collection and that process was covered during new user orientation, but you may refer to their help guide here.

For our Titan Krios GIF/K3 systems the references need a y-flip for cryoSPARC and there is a file in your references folder that explicitly states the gain reference to use. For other parameters, such as pixel size, Cs, etc… you may find them through the webviewer.

For more information please email memc [at] .
