What is chemical biopsy?
Chemical biopsy is a low-invasive method for assessing the quality of organ grafts using SPME probes.
How does the SPME method work?
SPME probes extract metabolites from tissue samples, which are then analyzed using LCMS.
What are the advantages of this protocol?
It allows for real-time monitoring of graft quality with minimal invasiveness.
What types of analyses are performed?
Metabolomic and lipidomic analyses are conducted to evaluate graft quality.
Can this method be used for other tissues?
Yes, the method can be adapted for various tissue types in metabolomics studies.
What precautions should be taken during sampling?
Ensure consistent timing and proper placement of probes to avoid contamination.
