Questo metodo produrrà un arricchimento di fosfopeptidi che può essere analizzato quantitativamente. Un certo numero di parametri possono essere modificati in questo protocollo, ma l&#39;aspetto più importante da ricordare è per preservare la vostra fosforilazione. Preparazione delle cellule per la quantificazione può essere ottenuto in molti modi diversi, ad esempio se non si possono etichettare le cellule in vivo, i tag come ICAT [3] o ITRAC [4] può essere utilizzato estrazione messaggio per etichettare...

quantitative phosphoproteomics in fatty acid stimulated saccharomyces cerevisiae

Questo protocollo descrive la crescita e la stimolazione, con l&#39;oleato di acidi grassi, degli isotopi pesanti e leggeri cellule di S. cerevisiae. Le cellule sono a terra con un procedimento cryolysis in una smerigliatrice mulino a sfere e la conseguente grindate portato in soluzione mediante solubilizzazione urea. Questa procedura permette la lisi delle cellule in uno stato metabolicamente inattivo, conservando la fosforilazione e la prevenzione riorientamento della phosphoproteome durante la lisi cellulare. Dopo la riduzione, alchilazione, tripsina digestione delle proteine, i campioni sono dissalati su colonne C18 e la complessità del campione ridotto di frazionamento mediante cromatografia di interazione idrofilica (HILIC). Colonne HILIC preferenzialmente trattenere le molecole idrofile che ben si adatta per fosfoproteomica. Peptidi fosforilata tendono ad eluire successivamente nel profilo cromatografico che le controparti non fosforilata. Dopo frazionamento, fosfopeptidi sono arricchite usando la cromatografia in metallo immobilizzato, che si basa sulla carica a base di affinità per l&#39;arricchimento fosfopeptide. Al termine di questa procedura i campioni sono pronti per essere analizzato quantitativamente mediante spettrometria di massa.
