NMR-Based Metabolic Phenotyping

Inquiry

Metabolic phenotype involves a comprehensive analysis of biological fluid or tissue samples. This analysis allows biochemical classification of individual physiological or pathological status, which is related to disease diagnosis or prognosis at an individual level and disease risk factors at the population level. NMR spectroscopy is a mature, universal and widely used analytical technique. It is one of the cornerstones of metabolic analysis, metabolomics, metabolomics and metabolic phenotype analysis. It applies to complex biological fluids and tissue samples.

The use of metabolic phenotype analysis has proved that it is possible to derive a new biochemical disease diagnosis assay and determine the combined biomarkers of the disease. In principle, it can be used to monitor the treatment effect. As an expert in the field of nuclear magnetic resonance, Creative Biostructure uses advanced NMR methods to improve data resolution, increase the detection limit of metabolic phenotyping analytes, and reliably quantify the components in complex biological fluids and tissue matrices.

Sample Requirement

NMR has the advantage of being non-destructive and is also applicable to complete tissues using the magic angle rotation (MAS) method, and provides detailed information about molecular structure, especially in complex mixture analysis. In addition, NMR can also be used to detect molecular dynamics and concentration. Creative Biostructure is equipped with complete NMR equipment for metabolic performance analysis. We can use 1H, 13C, and 2D studies to analyze the metabolic phenotype of the following types of samples.

  • Cell extract or secretion.
  • Human and animal tissue and biopsy extracts.
  • Body fluids (blood, serum, plasma, pancreatic fluid, prostate fluid, cerebrospinal fluid, urine, semen, digestive fluid, pathological fluid (such as capsule fluid), and drug delivery fluid (such as dialysis fluid), etc.).

If this method is to become a part of the mainstream clinical operation, of course, it is necessary to conduct a more rigorous evaluation of the biomarkers obtained in many small clinical studies and a more realistic evaluation of their effectiveness and cost-effectiveness.
