For adherente linjer, bør cellene løftes med forsiktig skraping i 1,5 ml av mediet holdes på is. Valgfritt: Hvis interne standarder benyttes, tilsette en egnet alikvot på dette trinnet. Kommentar: Quenching av cellenes stoffskifte er avgjørende for visse metabolitter. For analyse av tidsfølsomme metabolitter, bør prosedyrer som f...

Vilkårlige metabolomikk tilbyr et kraftig verktøy for å undersøke endogene eller xenobiotic biotransformasjoner, eller fange en metabolsk profil fra et utvalg av interesse. Utgangen av teknikken skalaer med oppløsning og sensitivitet av teknologien som brukes for å separere og analysere prøven, evnen til å håndtere de store datasett som genereres, og evnen til å utvinne datasett for nyttig informasjon (f.eks nøyaktig masse databasesøk). Nylig har dette vært tilrettelagt av fremskritt i høy oppløs...

På grunn av de siste teknologiske fremskritt innen HRMS, har vilkårlige, hypotese-genererende metabolomics tilnærminger bli en mulig tilnærming til analyse av komplekse prøver. En massespektrometre stand til 100.000 oppløsning tilrettelegge rutine lave delen per million (ppm) masse nøyaktighet har blitt allment tilgjengelig fra flere leverandører. 2,3 Denne massen nøyaktighet gir større spesifisitet og tillit i en foreløpig tildeling av analytt identitet, isotopiske mønstergjenkjenning, og adduct identifikasjon. 4 Når dette kombineres med en passende ekstraksjonsmetode og høy ytelse LC eller UPLC, komplekse blandinger kan analyseres med ekstra spesifisitet avledet fra oppholdstid data. 5 UPLC besitter større kromatografisk effektivitet og gir større følsomhet, oppløsning og analyse tid på å lage en større dekning av metabolome mulig. 6 De resulterende store datasett kan integreres i ethvertav multippel differensial analyse programvare og minelagt for nyttige mønstre eller individuelle analytter av interesse. 7,8,9,10,11 Antatte treff kan først identifisert ved hjelp av en kombinasjon av peak algoritmer, nøyaktig mass basert kjemiske formelen prediksjon, fragmentering prediksjon, og stoffkartoteket søk. Denne tilnærmingen gjør prioritering av målene for tidkrevende komplett strukturell identifikasjon eller for utvikling av mer sensitiv og mer spesifikk stabile isotoper fortynning UPLC / valgte eller flere reaksjon overvåking / MS studier som er dagens gullstandard metoder for kvantifisering. 12 Det varierende innholdet av biologiske prøver har ført til optimalisering av ekstraksjonsmetoder for urin 13, 14-celler, 15 serum, vev eller 16.. Denne protokollen har ekstraksjoner for celler, serum og vev. Der det er hensiktsmessig, har kommentarer og ytterligere referanser er inkludert for modificasjoner av prosedyren for å ta inkludering av stabile isotoper, eller for inkludering av spesielt ustabile metabolitter.

untargeted metabolomics from biological sources using ultraperformance liquid chromatography-high resolution mass spectrometry (uplc-hrms)

Her presenterer vi en arbeidsflyt for å analysere de metabolske profilene for biologiske prøver av interesse, inkludert; celler, serum eller vev. Prøven blir først separert i polare og ikke-polare fraksjoner ved en væske-væske-fase ekstraksjon, og delvis renset for å lette genetisk analyse. Begge vandige (polare metabolitter) og organiske (ikke-polare metabolitter) faser ved den første ekstraksjon blir behandlet for å undersøke et bredere spekter av metabolitter. Metabolitter er atskilt med forskjellige væskekromatografi fremgangsmåter basert på deres skillevegger egenskaper. I denne metoden, presenterer vi microflow ultra-ytelse (UP) LC metoder, men protokollen er skalerbar til høyere strømmer og lavere trykk. Innføring i massespektrometer kan være gjennom enten generelle eller sammensatte optimaliserte kilde forhold. Påvisning av et bredt utvalg av ioner blir utført i fullt scan mode i både positiv og negativ modus over en bred m / z rekkevidde med høy oppløsning på en nylig calibrated instrument. Label-free differensial analysen er utført på bioinformatikk plattformer. Søknader med denne tilnærmingen er metabolismen screening, biomarkører, og narkotika utvikling.

Resultatene som presenteres viser utvalgte data fra en 6-timers behandling av SH-SY5Y glioblastoma celler med plantevernmidler og mitokondrie-komplekset Jeg inhibitor rotenon. For korthets skyld blir bare den organiske fase positive virkemåte data presentert. Prøvene ble behandlet og analysert som beskrevet ovenfor (figur 1, tabell 1, 2 Table) og lastet opp på to differensialanalyse plattformer for label-free kvantifisering, sil og XCMS online. Selv om et stort antall treff (figur 2, figur 3)...
