Recharge Rates

The Image Analysis component of the PLIF Core maintains its own recharge system where the income is used to cover part of the salary of the morphology technician Mr. Nelson. Work for non-Center members is only done on a time-available basis and at a 50% higher amount for technician time (since the Core provides 50% of the technician, Mr. Nelson’s, salary). The Center member rates are summarized below.

The Proteomic facilities are available at a highly subsidized rate as they do not include instrument service contract costs. GI Center members can be approved for up to $1000 of these recharges (annually) billed directly to the GI Center. The fee structure is displayed in the table below.

The Protein Folding Diseases Initiative Resources, several services are available (summarized below). The technician who is supported by the PFD initiative is contacted directly by phone or email. Antibody aliquots or tissues are typically provided within 2 business days of making the request. If a particular antibody on the list is not available, the technician will order it from the vendor (with express shipping) and inform the investigator when it arrives. No more than one aliquot per antibody is provided to any given investigator. The PFD has not had to set limits on how many antibodies can be tested by a given investigator, but limits (e.g., no more than 5 per month per investigator) may be set if warranted. The antibodies are purchased by the PFD Initiative.

 The prices listed below are subject to change.
