  • Shuttles are ADA compatible

Parking at the Chesterfield
Duke visitors have a two-hour parking option, which is first come/first served access, to the visitor parking lot at the back of the building near the railroad tracks. We share this 2 hour parking with other tenant's visitors, and are not designated a certain proportion of parking for our guests at this site. Do not park beyond the fencing or cones; this is a construction area.

We have designated guest parking under the building and that can be reserved for up to six spaces for School of Medicine, and seven spots for School of Engineering per day. There are two calendars (below) that you can use to reserve parking spaces under the building. Please note if the current total of 13 spaces has already been met, then other accommodations will need to be made.

For larger events that might exceed the total number of parking or events lasting longer than two hours, we typically work with the building management to open up the 704 W Pettigrew St parking deck for more visitors on the day of the event. 

1. Sample Submission Consultations

Prior to submitting any samples for new projects, please contact us.

You can submit samples and check the status of submitted samples with PAMLIMS (see below).

If the samples are extensions of previous projects, please contact the scientist you previously worked with to discuss these samples: 

Proteomics Project Leads:

Metabolomics Project Lead:

We cannot accept samples without consultation and the electronic submission of the sample.

Priority will be given to DCI members and time-sensitive projects, including preliminary data needed for timely grant submissions and additional experiments needed for manuscript resubmissions.

2. Electronic Sample Submission Process

Effective January 17th, 2023, our Facility will be using a new sample submission called PAMLIMS. Following a consultation with one of our staff members (see step 1 above), that staff member will send you a PAMLIMS link to a) create an account and b) electronically submit your samples. There will be additional instructions within the PAMLIMS system.

** Note that existing projects and data currently in Express Repository has been archived. To retrieve data stored on Express, you will need to contact us and it will be re-mounted on Duke Box.

If you have any questions on this new system, please feel free to contact us or browse the "Q&A" section within PAMLIMS.


3. Instructions for Sample Delivery 

Please follow the instructions on our website for project consultations and subsequent sample delivery, and review the new sample delivery procedures below. If you have any questions, contact us.

We utilize video conferencing solutions for all project discussion.

The shipping address for samples sent by other delivery methods is below. Please ensure the samples have been submitted electronically before shipping samples.

Procedures for Sample Delivery 

  1. Submit your order into our system and prepare samples for delivery. You must contact your DPMCF Project Leader, Erik SoderblomLucas Li, or Matt Foster before submitting samples electronically. This will ensure our lab is ready to analyze your samples.
  2. Samples can be delivered directly to the Chesterfield via prior arrangement and scheduling with your DPMCF contact. Our scientists will meet you at the front door and collect your samples. Bring samples and a hard copy of the electronic submission(s).
    1. Use wet ice if samples need to be stored at 4oC.
    2. Use dry ice if samples need to be stored at -80oC.
    3. Ensure that the sample name on each tube matches the sample name on the hard copy of the order, and the order number of samples delivered matches the number of samples in your order.
  3. For delivery via the on-campus drop site, bring samples and a hard copy of the electronic submission(s) to Heather Hemric, ZhengZheng Wei or So Young Kim in MSRB3. They will accept samples by appointment between 2 - 3 PM on Mondays and Tuesdays. Please call (919)-684-8224 or email to notify them when you will be submitting samples. They will meet you at the lobby of MSRB3 to receive your samples, which will be delivered to the Chesterfield by courier the next business day.
    1. Use wet ice if samples need to be stored at 4oC.
    2. Use dry ice if samples need to be stored at -80oC.
    3. Ensure that the sample name on each tube matches the sample name on the hard copy of the order, and the order number of samples delivered matches the number of samples in your order.
    4. The staff at MSRB3 will review your order in the system with you, help make any necessary changes and ensure your samples are properly packaged for transport.
  4. Scientists from DPMCF will be available by phone to discuss any issues that may arise.

Sample Drop-Off Hours at MSRB3:

  • Monday – Tuesday: 2 – 3 P.M. (sample will arrive in Chesterfield next business day)

A courier will pick samples up from MSRB3 between the drop-off periods and will bring samples to Chesterfield the next business day, arriving at Chesterfield at ~ 2:30 P.M.
We are committed to ensuring that your samples are properly transported for analysis. Please do not hesitate to contact any DPMSR scientist with questions or concerns.
*NOTE: If you have samples that need to be processed in a time-sensitive manner (e.g. co-IP samples that have not been eluted off a resin or beads), please let us know prior to drop-off so we can coordinate same-day delivery and sample prep.
*NOTE: Due to transport issues, we can no longer accept your full SDS-PAGE gel.

  1. Cut out the bands to be analyzed using the normal precautions to minimize keratin contamination.
  2. Place the bands in a small volume of water, PBS or 50mM ammonium bicarbonate buffer in a micro-centrifuge tube.

We offer SDS-Page protein separation as a service. If we perform this step, we will share the image of the gel with you prior to cutting bands to ensure that the appropriate band(s) are excised and analyzed.

SDS-PAGE Gel-band Handling Recommendations

Although nearly any SDS-PAGE system can be utilized upstream of an LC-MS analysis, we recommend Invitrogen’s NuPAGE Bis-Tris mini-gel system. A good general purpose gel covering a large MW range (6-200 kDa) is the 4-12% gradient gel (Cat. No NP0321) using MES running buffer. These pre-cast gels provide excellent resolution, fantastic staining sensitivity (10 ng BSA using colloidal blue staining kit, Cat. No. LC6025), and are highly compatible with downstream LC-MS analysis. Additional product information.

Important reminders to avoid keratin contamination:

  1. Any gel manipulation prior to trypsin digestion should be done in a BSC or laminar flow hood.
  2. Wear nitrile (not latex) gloves.
  3. Wear a lab coat and make sure there is no gap between your coat sleeve and the gloves (lab tape works well).
  4. Ensure that gels are cut against a clean glass plate (methanol rinse) using a new, methanol-cleaned scalpel or razor blade. Please cut as close to the margins of the band as possible, to avoid background contamination from the non-stained region of the gel.
