Intracellulare di Ca 2 + gioca un ruolo importante in molte condizioni fisiologiche e patologiche, quali rilascio dei neurotrasmettitori (3), potenziale d&#39;azione cardiaco (4), la contrazione delle cellule muscolari (5), trasduzione del segnale cellulare (6-7), e la morte cellulare eccitotossico ( 8). Misura di Ca 2 + intracellulare livelli aiuta a chiarire cambiamenti funzionali di Ca 2 +-permeabile canali nella membrana plasmatica o organelli intracellulari e il contributo di ...

cell-based calcium assay for medium to high throughput screening of trp channel functions using flexstation 3

FlexStation il Molecular Devices &#39;3 è un banco di lavoro multi-mode capaci di lettore per micropiastre automatico di misurazione della fluorescenza multi-pozzetti. E &#39;ideale per medie e high-throughput schermi in ambienti accademici. Ha un modulo integrato di trasferimento del liquido dotato di un multi-canale pipetter e la macchina legge una colonna alla volta per monitorare le variazioni di fluorescenza di una varietà di reagenti fluorescenti. Per esempio, FlexStation 3 è stato usato per studiare la funzione di Ca 2 +-permeabile canali ionici e G-proteine ​​recettori accoppiati misurando le variazioni di libero intracellulare di Ca 2 + livelli. Transitori recettore potenziale (TRP) i canali sono una grande famiglia di canali di comunicazione non selettivi che svolgono un ruolo importante in molte funzioni fisiologiche e fisiopatologiche. La maggior parte dei canali TRP sono il calcio permeabili e indurre influsso di calcio al momento dell&#39;attivazione. In questo video, dimostriamo l&#39;applicazione di FlexStation 3 a studiare il profilo farmacologico del canale TRPA1, un sensore molecolare per numerosi stimoli nocivi. Cellule HEK293 transitoriamente o stabilmente esprimere umano TRPA1 canali, coltivate in piastre a 96 pozzetti, vengono caricati con Ca 2 +-sensitive colorante fluorescente, Fluo-4, e le modifiche fluorescenza in tempo reale in queste cellule sono misurati prima e durante l&#39;applicazione di un agonista TRPA1 utilizzando la modalità FLEX del FlexStation 3. L&#39;effetto di un putativo TRPA1 antagonista stato anche esaminato. I dati vengono trasferiti dal software SoftMax Pro per la costruzione di concentrazione-risposta di TRPA1 attivatori e inibitori.
