Analysis available

The CPC as dedicated NMR and LC-MS instrumentation and offers a broad range of services from untargeted profiling assays  (for broad-coverage discovery applications) to targeted assays (for specific metabolite classes or pathways).

 As a brief introduction, the analysis available and the coverage they offer are summarised below. Please note that this information is provided for guidance only and we would encourage researchers to contact us to discuss their requirements and needs in more detail.

Additionally, due to the close working relationship, the CPC is also able to access other instrumentation available in the Division of Computational and Systems Medicine (CSM). To request access to the shared CPC and CSM instrumentation and services, please contact us and we can put you in touch with the right teams.

Targeted methods

The range of targeted assays that the CPC offers are gradually expanding and different analysis are currently being developed and validated within the division of Computational and Systems Medicine. The following targeted methods are already available in the CPC:

We can develop specific analytical targeted methods if necessary to understand the patient journey better. Please enquire for further details if you have a specific assay under consideration and would like further advice regarding availability and timeline for the development of such assay.

The CPC is also set up to run Biocrates AbsoluteIDQ Metabolomics Kits, which identify and quantify a large number of key metabolites from different compound classes, including acylcarnitines, amino acids, hexoses, phospho- and sphingolipids and biogenic amines.
