Experimental methods
metabolomics by mass spectrometry assay
What this technique is
- Category
- Omics
- Principle
- A mass spectrometry assay that identifies and measures metabolites.
- Input samples
- mouse serum · mouse liver tissue extract
- Research questions
- Not provided
- Output and readout
- 非靶向质谱给出代谢物谱并按组间多元统计（如 PCA 分离）与差异代谢物判读。
- Applicability
- 用于代谢表型研究的小鼠血清/组织 LC-MS 或 GC-MS 非靶向代谢组学，如膳食与基因型干预的代谢指纹比较。
- Limitations
- 非靶向结果偏重相对定量，绝对定量需标准品；平台、提取与归一化流程不同批次间不直接可比。
