Summary

Automatic Translation

Cellulære ion transport kan ofte vurderes ved at overvåge intracellulære pH (pH,jeg). Genetisk giver kodet pH-indikatorer (GEpHIs) optisk kvantificering af intracellulære pH i intakt celler. Denne protokol detaljer kvantificering af intracellulære pH via cellular ex vivo live-billeddannelse af Malpighian tubuli af Drosophila melanogaster med pHerry, en pseudo-ratiometric kodet genetisk pH-indikator.
