Training for new users consists of:

  • lab safety training,
  • operation of the instrument and associated software,
  • use of data analysis software,
  • exporting or presenting data,
  • clean up and shutdown of the instrumentation.

Once the training is complete, researchers may schedule their experiments through the director of Biophysical Characterization (Lizz Bartlett) or online through FOM (Facilities Online Manager) at fom.umass.edu/fom

Once the training is complete, researchers may schedule their experiments through the director,  Lizz Bartlett dbartlett@umass.edu or online through Facility Online Manager (FOM) (access and reservations)

General
The Facility is staffed from 8:00AM until ~5PM on weekdays. Once trained, all registered users may request after-hours access. No one may gain access to the Facility using an ID not their own or use instruments for which they are not trained.

Training
All users must receive proper training before being permitted access to the Facility. Training is provided by the core director.

Scheduling
The use of instruments or training, by the UMass-Amherst community, requires an advance reservation using Facility Online Manager (FOM). If you do not have an account, please log in here: https://fom.pse.umass.edu/fom/ to create one. You will be expected to make reservations and logon to instruments using your FOM account.

Once you have reserved instrument time, please make every effort to be there and use it. If the Facility is not notified or the reservation canceled, you may be billed for any time you reserve. If you have made a reservation and wish to cancel it, please do so using FOM as soon as you can. This is only fair to all who use the Facility. We may bill no-shows and late cancellations, at our discretion.

Usage and Rates
Instruments are used (and billed) on an hourly or daily basis. For instrument usage totaling less than an hour during a day, we charge for a full hour. For usage totaling more than an hour, we charge for the actual time used. The daily rate assumes an 8-hour period. The usage patterns of the SEC-MALS, Biacore T200, ProteomeLab XL-I, and MicroCal AutoiTC200 preclude hourly rates for these instruments; the unit rates for these instruments are half day (4 hours) or full day (8 hours) of use.

Housekeeping
Users are expected to keep the equipment and equipment areas safe, tidy, and very clean. Repeated failure to maintain this policy may result in loss of use privileges.

Until an offsite server is established, users are encouraged to remove their data from the hard disk of the computer immediately after each session. Long term storage of data on the equipment computer is not recommended as the data can be inadvertently removed or overwritten without any warning.

Lizz Bartlett, PhD
Bringing thirteen years experience as the lead formulation scientist at ImmunoGen, Inc. developing six novel formulations for antibody-drug conjugates, resulting in four patents, in addition to creating a biophysical characterization group. As well as ten years as a lead scientist in Drug Product Development at Genetics Institute (now Pfizer), integral in developing the formulation for BeneFIX, resulting as co-inventor on two patents.

  • The Biophysical Characterization Core Facility at UMass Amherst is absolutely top-notch with state-of-the-art instrumentation. But the thing that separates this facility from others like it is its Director, Lizz Bartlett. With over 30 years of industry experience, she will not only guide you in selecting and setting up the instrument, but will also aid you in designing the experiment to best answer your question.

    —Joe Tilitsky, Gierasch Lab

  • The biophysical characterization facility enabled me to run experiments, collect data, and make conclusions that have been critical to my research. It's a wonderfully curated collection of instruments with excellent training and support from Lizz Bartlett. I'm grateful to have the opportunity to use this invaluable resource on our campus.

    —Libbie Haglin, Thompson Lab

  • Working on biophysical characterization core instruments has been a terrific plus for both research and training for my own and many other groups working at the chemistry-biology interface. With guidance from the Director Lizz Bartlett, we were able to consider multiple methods to follow up on an interesting discovery and choose the best one to provide key information for the project.
