The Iron and Heme Core’s primary mission is to facilitate research into the role of heme, heme precursors and transition metals in both normal and disease states. The iron and heme core lab has extensive experience with the separation and identification of tetrapyrroles and with running and developing heme biosynthesis pathway enzyme assays.

The Iron and Heme Core provides analysis of metals, precursor porphyrins and heme. The core will measure activity of the enzymes responsible for heme biosynthesis. Analysis and quantification of heme and its precursors can be obtained for cell pellets, tissue, whole blood, urine, feces and other complex biological materials. Analysis of enzyme activity can be provided for cell pellets, tissue and blood.

Porphyrin Analysis

Porphyrins from urine, feces, cell lysates, serum, blood, media concentrates from mammalian cells and yeast and other biologic samples are analyzed using a Waters UPLC system. Porphyrins are separated on a reverse-phase C18 column, 2.1x 100 mm BEH, and visualized with the tandem high sensitivity photodiode... Show more »

Porphyrin Analysis

Porphyrins from urine, feces, cell lysates, serum, blood, media concentrates from mammalian cells and yeast and other biologic samples are analyzed using a Waters UPLC system. Porphyrins are separated on a reverse-phase C18 column, 2.1x 100 mm BEH, and visualized with the tandem high sensitivity photodiode array and fluorescence detectors of the UPLC.

Standard molecules analyzed include: heme (as hemin chloride), the precursor porphyrins (uroporphyrin, heptacarboxylporphyrin, hexacarboxylporphyrin, pentacarboxylporphyrin, and coproporphyrin) of both I and III isomers, protoporphyrin IX and zinc protoporphyrin IX. We may also assay for bilirubin and biliverdin. (Standards for most of these are available from Frontier Scientific, Logan, UT, and the remainder are generated by our lab)

There are instances where additional absorptive or fluorescent peaks are observed with “tetrapyrrole signatures” that do not correspond to the standard molecules listed above. When standards are not available and there is enough sample, fractions can be collected, pooled and analyzed by our sister CIHD core, the Metabolomics Core, at the University of Utah.

UPLC analysis of total heme and PPIX

A Waters Acquity ultra-high pressure liquid chromatography (UPLC) system equipped with a reverse-phase C18 column, a photodiode array detector and a fluorescence detector are used to determine total heme and PPIX. Samples are subjected to solvent extraction and all noncovalently associated heme and PPIX are solubilized and quantified. Hemin chloride (the Fe+3 equivalent of heme formed during sample processing) and PPIX are used as standards for quantitation.

Pricing includes sample processing, protein quantification for normalization (where needed), and assay run in triplicate.

Spectral analysis of Heme

An Agilent 8453 diode array spectrophotometer can also be used for the spectrophotometric analysis of hemes. Typically, samples are solubilized in 200 mM NaOH in the presence of pyridine to obtain the pyridine-ferrohemochrome derivative spectra. Simultaneous determination of hemes a, b, and o, is possible from the pyridine hemochrome spectra. Each heme species is quantified using the well-established alpha band extinction coefficients at characteristic absorbance maxima obtained from the reduced-minus-oxidized spectra.

Pricing includes sample processing, protein quantification for normalization (where needed), and assay run in triplicate.
