Our great support Henri has been with IsoLife for 12.5 years. We celebrated this happy event with an artistic visit to the Depot of Boijmans van Beuningen in Rotterdam, followed by a cruise through the harbour and a climb up the Euromast.
We are very greatful to Henri for his continuous commitment to IsoLife and hope that he will be Head of Sales for a long time to come!
Two exciting solid-state NMR papers published on cell wall structure
January 27, 2022.
First use of U-13C Lignin for monitoring lignin degradation in compost
December 16, 2021.
Using uniformly 13C-labelled plants and ss-NMR, the group of professor Tuo Wang published two papers on cell wall structure. Kirui et al. showed that the extent of glycan-aromatic association increased across grasses, hardwoods, and softwoods, having implications for biomass conversion. Poulhazan et al. revealed that in microalga starch was the most abundant polysaccharide in a well-organized and highly rigid cell structure.
The first paper of a project, co-sponsored by IsoLife, supported by NWO-ENW-GSGT and entitled ‘The fate of nutrients captured in the dark film of mushroom substrate’. Katharina Duran investigates the formation, conversion, function, and bioavailability of compost dark films and their nutritive properties for Agaricus bisporus.
First results published on the nanostructure of U-13C Pinus radiata cell walls

New in IsoLife‘s portfolio: Sophora flavescens
October 6, 2021.
Producing U-13C Pinus radiata has been a challenge, but the results of the current paper by Cresswell et al. using MAS-NMR now clearly explain the influence of cell wall dehydration on timber mechanical properties. Read more>>
We proudly present our new product U-13C Sophora flavescens, the traditional Chinese medicinal herb (Kushen). The root of Sophora is used in e.g. China, Japan, and India to treat diseases like asthma, jaundice, dysentery, and many others. Read more>>

IsoLife congratulates Mirjam Kabel (Food Chemistry WU) with our new, joint project
October 17, 2019.
A new quantitative 13C-IS py-GC-MS method has been developed using U-13C Lignin as an internal standard to measure highly accurate lignin contents and acquire valuable structural information from extremely small samples (10-100 μg).
This joint project was granted by NWO-TTW-OTP and entitled ‘Lignin as intrinsic tracer for gastrointestinal transit behavior and feed digestion (LiFeTracer)’. The aim of LiFeTracer is to set-up methodology for using U-13C Lignin or a recalcitrant lignin-fraction, intrinsically present in the feed, as tracer in digestion studies.
Molecular structure of U-13C fungal cell walls unravelled
July 16, 2018.
Now also available: 0.1 atom % 13C Maize (depleted)!
May 15, 2018.
IsoLife‘s U-13C Aspergillus fumigatus has been used to unravel the structure of fungal cell walls with solid-state NMR. The results of Kang et al. (2018) published in Nature can be used to promote the development of cell wall-targeted antifungals to combat invasive fungal infections in humans.
Exemption for U-13C Cannabis and U-13C Cannabinoids
November 17, 2017.
IsoLife‘s pure U-13C Lignin used as extremely accurate Internal Standard
September 19, 2017.
IsoLife has acquired an exemption from the Dutch Ministry of Health, Welfare and Sport for supplying 13C labelled cannabis plants and cannabinoids to the international research community.
Our recently developed, pure U-13C Lignin from maize (~90%) has been used for the first time as Internal Standard for lignin quantification with Pyrolysis-GC-SIM-MS (Van Erven et al., 2017). The method was shown to be extremely accurate and proved to be a promising alternative for high-throughput quantification of lignin in biomass samples.

IsoLife publication:’No de novo sulforaphane biosynthesis in broccoli seedlings’.
December 17, 2010.
Several contributions showed that 13C-applications do extend the possibilities to identify active soil microbes assimilating carbon from different substrates in complex ecosystems. For those who missed it: download our poster presentation here.
The isothiocyanate sulforaphane, present in significant amounts in broccoli (Brassica oleracea L.) seedlings in the form of its precursor glucoraphanin, has been identified as an inducer of quinine reductase, a phase-II detoxification enzyme known for its anticarcinogenic properties. Here, we unambiguously demonstrate in that sulforaphane is not biosynthesised de novo during the first week of seedling development. Both 12C (99 atom%12C) and 13C (98 atom% 13C) broccoli seeds were produced and subsequently germinated and grown either in a 13CO2 or a 12CO2environment. Afterwards, the labelling degree of sulforaphane in seeds and in seedlings was analysed by HPLC–MS. We conclude that sulforaphane exclusively originates from seed reserves and that de novo biosynthesis is not detectable in broccoli seedlings. Our findings have been published in Food Chemistry (for further details see Applications). Ask a reprint.

Healthy food: Potato products with low caloric values and high fiber contents.
March 1, 2009.
The Dutch minister of Economic Affairs Maria van der Hoeven and ABN AMRO have awarded IsoLife’s highly innovative R&D plans with the TechnoPartner Certificate. The certificate acknowledges the courage, knowledge, and perseverance to further develop her innovative initiatives to commercial successes.
Potatoes are a good, natural source of carbohydrates, energy, dietary fiber, minerals, and vitamins.13C-labeled potatoes are extremely helpful to investigate the caloric properties and the behavior of functional components of specific potato varieties in a normal daily diet. For this purpose, IsoLife has produced several stable isotope labelled potato varieties during recent years. One of the projects – co-financed by ‘Samenwerkingsverband Noord-Nederland’ and performed by IsoLife in co-operation with the partners HZPC, Aviko and the University Medical Center Groningen – investigated whether the caloric value of potatoes and potato products could be (further) decreased by specific procedures in potato breeding or product processing.
HZPC Holland BV is a breeding company and a trade company for the development and sales of innovative potato varieties in the potato supply chain with focus on potatoes for consumption and potatoes for French fries, chips and the food chain.
AVIKO BV is the largest Dutch producer of potato products with focus on health aspects.
The ‘Center for Medical Biomics’ (UMCG), the department of professor Roel Vonk, has contributed in areas like digestion, fermentation, and metabolism of potato components in relation to human health. The UMCG has co-ordinated the large EU-research project EUROSTARCH
The results, based on detailed experiments with 13C-labelled potato products, show that the caloric value of potato products can indeed be (further) decreased through changes in their composition.
This project was co-financed by the European Community, the European Regional
Development Fund, and the “Samenwerkingsverband Noord-Nederland (SNN)”, a joint agreement between the provinces of Drenthe, Groningen and Fryslân. EZ/KOMPAS under number AA099.

Methane emission from plants: Yes they do! No they don’t!
April 27, 2007.
The first uniformly 13C-labelled tomatoes (cv ‘MicroTom’) were harvested.
July 20, 2006.
In 2006, Nature published a sensational article by Keppler et al, who claimed that plants would be able to emit methane under aerobic conditions. A Dutch consortium consisting of IsoLife, Plant Research International, Plant Dynamics, Nijmegen Radboud University, Utrecht University tried to reproduce their results using a novel technique with uniformly 13C-labelled plants. We found methane emissions that were between 0.1% and 0.3% of the rates reported by Nature. Apparently, the textbooks do not have to be rewritten. Our findings have been published in New Phytologist (for further details see Application; for more news read the News commentaries). Ask a reprint.
We are proud to have served our customers with mature, uniformly (~98% 13C) labelled tomatoes.
