ProteomicsProtein stable isotope fingerprinting (P-SIF): Chocolate Pots (Yellowstone) biomass
Protein stable isotope fingerprinting (P-SIF) is a method to measure the carbon isotope ratios of whole proteins separated from complex mixtures, including cultures and environmental samples. The goal of P-SIF is to expose the links between identity and function in microbial ecosystems by (i) determ...

ProteomicsProteomes of twenty bacterial, archaeal and eukaryotic species for bench marking of Direct Protein-SIF (stable carbon isotope fingerprinting proteomics)
We developed a method that allows measuring the stable carbon isotope composition of individual species in microbial communities using metaproteomics. We call this methods “Direct Protein-SIF”. To benchmark this method, we measured twenty pure culture species using the Direct Protein-SIF method as w...

ProteomicsLinking Intestinal Microorganisms to their Diet-derived Growth Substrates Using Protein Stable Isotope Fingerprinting (Protein-SIF)
The aim of this study was to directly link intestinal microorganisms to their diet-derived in vivo growth substrates using protein stable isotope fingerprinting (“Protein-SIF”)(Kleiner et al. 2018, PNAS 115(24)). We conducted studies in gnotobiotic mice (C57BL/6J) colonized with a community of 13 hu...

ProteomicsMetaproteomics of the marine gutless oligochaete Olavius algarvensis and its symbionts to determine stable isotope fingerprints using Direct Protein-SIF
We developed a method that allows measuring the stable carbon isotope composition of individual species in microbial communities using metaproteomics. We call this methods “Direct Protein-SIF”. We validated and tested the method extensively using pure cultures (PXD006762) and mock communities (PXD00...
