This service group deals with qualitative and quantitative analysis of metabolites and nutrients, either labelled with stable-isotopes (2H, 13C, 15N, 18O)- or unenriched, isolated from biological fluids (blood, saliva, urine, milk), tissues (e.g., liver, muscle) and excreta of e.g. cattle, pig, sheep, chicken and mice as well as feedstuffs.
This allows functional phenotyping of metabolic processes related to nutrition such as
by dosing animals in vivo with stable-isotope labelled tracers and then follow-up on their fate in the body.
To analyse nutrients or metabolites chemically labelled with stable isotopes or at natural abundance (2H, 13C, 15N, 18O) to quantify nutrient and energy metabolism in vivo.
