Iron and Heme Core Facility
The Iron and Heme Core Facility has been in operation since 2016 and is part of the NIDDK sponsored Center for Iron and Heme Disorders (NIH U54DK110858). It is also serves as one of the University of Utah shared-resource Health Science Cores facilities which are established service/recharge centers offering services to research facilities across the country. The Iron and Heme Core provides analyses of heme and precursor compounds and metals present in biological samples. The core specializes in the UPLC quantification of heme and other tetrapyrroles, and the measurement of activities of all eight enzymes in the heme biosynthetic pathway, and in the ICP-MS analysis of iron and other common metals in biological systems.
This Facility is equipped mainly with two Waters Acquity ultra performance liquid chromatography (UPLC) systems (Classic and H-Class Plus), each with its own solvent manager, sample manager, tandem high sensitivity photodiode array and fluorescence detectors, and reverse phase C18 column. An Agilent 7900 ICP-mass spectrometer with an SPS4 auto sampler is dedicated for metal analysis. Other supporting equipment allow for sample storage, handling, processing for analysis and data processing, and some of these are a dark room, fume hoods, a deoxygenation system, refrigeration and freezer space, a spectrophotometer, centrifuges, various tissue and cell disruptors, hot blocks, mixers and sample dryers.
With more than a quarter century of performing laboratory research on the heme biosynthetic pathway, the people with the Iron and Heme Core have contributed to high impact research that has lead to publications in PNAS, Elife, J. Biol. Chem., MicrobiologyOpen, Chemical Reviews, and in Blood Cells, Molecules, and Diseases.

* Only two components may be quantified at most in the same run. If all three were requested, that would be two runs for the same set of samples. If samples do not allow quantification of two components in the same run (amounts present are very disparate), another run will be performed to complete the requested service. The extra run would require 1/2 of consumables, no BCA, and 1/2 tech time. (For example, blood and spleen have very high heme and need two runs to quantify heme and PPIX/ZnPPIX.)
** For analyses on all tissues not needing enzyme activity measurements.

Charge Rates Procedure / Federal Facilities and Administration (F&A) Rate
Part of the University’s agreement with the Federal Government regarding F&A is that the University will not offer a lower than F&A rate to other kinds of sponsors. That means that the University has to use, at minimum, the same rates for commercial sponsors as it does for the Federal Government. The University would jeopardize its relationship with the Federal Government (the University’s single largest sponsor) if it were to accept rates lower than the current federal F&A rate.
The current F&A Rate is: 54%
The facility internal rate is used when exclusively internal funding sources are used. The F&A / external academic rate applies when external funding sources are used i.e. Federal Government or other academic universities. For more information about F&A rates at the University of Utah please see: 6.3 Indirect Costs/Facilities and Administrative Costs (F&A)
Preparation of Samples for Shipping
For most assays please send the samples as follows:
| Sample Type | Minumum Quantity | Form/Condition |
| Serum, Body Fluids | 1 mL | Quickly Frozen |
| Cells | > 100 uL packed cell pallet | Washed with PBS, pelleted, supernatant discarded and then frozen |
| Tissue | ~ 100 mg | Flash Frozen |
| Fresh Blood | 1 standard collection tube | With anticoagulant, in ice bath, and covered with foil |
| Feed and other complex/hard materials | 1 g | dried and ground to fine powder |
- Please send all frozen samples packed in dry ice for overnight shipping and weekday delivery to:
Iron and Heme Core Facility
Wintrobe Research Building Rm #621
26 North Medical Drive
Salt Lake City, UT 84132
Notify the Iron & Heme Core to ensure that someone is available to receive the samples. - Please contact us for the quantity needed if you want us to run multiple assays per sample.
- Unless otherwise requested, results of analyses heme and its precursor compounds shall be reported in nano- or picomoles per mg protein in the sample, and enzyme activity shall be reported as nano- or picomoles product per mg of total sample protein per hour.
- Please notify us if you wish to receive leftover samples after processing and assay has been completed.
- A FedEx number is required if the project is for an external user.
- All samples will be discarded 30 days after results have been sent to the investigator’s lab, unless we receive a return request.
