About the instrument

Scientific instrument
Cressington 208 iridium sputtering tool

Iridium is useful for coating samples before electron microscopy. The Cressington 208 iridium sputtering tool provides very smooth, conformal coatings which are free of the grain structure found in films of Au or Au-Pd. Chromium would also be a good choice for coating SEM samples, but iridium oxidizes much more slowly, and so it has an advantage over fine-grained chromium films. 

A sputter coater for gold is located next to the chromium system. Gold is used for coating electron-beam resist before lithography, but it is not a good choice for SEM samples.

    Metabolic flux and enrichment studies using MIMOSA

    In this subcore, parameters of cellular and tissue metabolic flux are assessed by incorporation of stable isotope labeled tracers (e.g., 13C, 15N, 2D) into metabolism. The CMC uses the targeted mass isotopomer multi-ordinate spectral analysis (MIMOSA) platform to interpret stable isotope labeling patterns for calculation of rates of discrete steps in glycolytic and mitochondrial metabolism. Such measurements can be used to identify differences in fuel usage (e.g., glycolysis vs. beta-oxidation), and non-oxidative (reductive carboxylation, anaplerosis and cataplerosis) contributions to the TCA cycle.

    Islet isolation and function

    In this subcore, our technical expertise in isolating rodent islets including rats, mice and most recently ground squirrel islets, from the pancreas ex-vivo allows researchers to study the intact islets for their studies or to proceed with substrate stimulated insulin secretion functional studies using our BioRep Technologies Islet Perfusion Systems (8-channel and 12-channel) offered by our core. For non-rodent islet studies, human donor islet procurement assistance as well as unction studies are also offered.
