Information for Project Initiation, Sample Submission, and Inquiries

To initiate a project, submit a sample, or schedule ­­instrument time, please follow the WORKFLOW described (on right).

All projects and services are subject to approval by the Facility Director.  Most new projects require a consultation prior to initiation of work.  Consultations include advice on the best experimental approach, timing of the experiment, sample preparation and charges.  Samples are accepted only after the project has been approved and assigned to a Facility staff member.

Rates.  Our rate sheet captures the per sample cost or hourly rate for most of our services.  In general, costs for most proteomics projects can be determined from the rate sheet.  However, most small molecule projects are quotated by proposal and initiate following mutual acceptance. 

The Facility will not accept BIOHAZARDOUS and RADIOLABELED samples.

RG-3 or select agents ( WILL NOT BE ACCEPTED unless inactivated by a process approved by an Institutional Biosafety Committee (IBC).

Guidelines for submitting samples for protein analysis

Excised gel bands should be placed in 0.5 ml microcentrifuge tubes previously washed with 1% formic acid in 50% ethanol for 5 minutes (discard wash).

****Keratin contamination will always be observed.
Precautions must be taken to minimize contamination****
1. Wear gloves at all times and work with a mask or shield when cutting gel bands.
2. Thoroughly wash and methanol rinse anything that will come in contact with the sample, i.e., gel apparatus, staining trays, gel excising equipment and tubes.  Rinse the microcentrifuge tube and its cap with 1% formic acid in 50% ethanol before putting in the gel band.


Guidelines for shipping

In general, most samples should be shipped in a sealed container containing dry ice. For compliance on packaging and transport of hazardous substances see IATA ( and DOT ( for additional guidance.

Samples may be shipped by overnight service to:
