adjective ˌsuːpəˈneɪt(ə)ntˌsupərˈneɪtnt

technical

Denoting the liquid lying above a solid residue after crystallization, precipitation, centrifugation, or other process.
浮在上层的
carefully transfer the supernatant fluid into a 15 ml centrifuge tube
Example sentencesExamples
- Samples were then centrifuged (17,000 × g for 10 min), and supernatant fluid was stored at - 20°C for VFA analysis.
- Ammonia N was determined on the supernatant fluid using the phenol-hypochlorite procedure.
- The resultant supernatant fraction was used for the determination of lipid peroxidation and glutathione.
- The supernatant fluid was filtered and centrifuged.

noun ˌsuːpəˈneɪt(ə)ntˌsupərˈneɪtnt

technical

A volume of supernatant liquid.
浮在上层的液体
the supernatants were filtered and analysed
Example sentencesExamples
- All extracts were centrifuged at 10000 rpm for 5 min, and the supernatants were then evaporated under vacuum to dryness and resuspended in appropriate solvents to a final concentration of 1 mg/ml.
- The suspensions were spun at 1000 g for 30 minutes and the supernatants were filtered and lyophilized.
- The homogenates were then centrifuged at 3000 rpm for 15 min and the supernatants were used for determination of the lipid peroxide level via the MDA method, as described above.
- The tubes were centrifuged at 5000 rpm for 2 min, and the supernatant discarded.
- After various time intervals the supernatants were removed, cell samples were fixed with paraformaldehyde solution for 30 minutes at room temperature.
