Description

General description

Guanosine 5′-triphosphate (GTP) is a purine trinucleotide. GTP is a substrate for a wide range of G-protein coupled receptor (GPCR) GTPases, as well as cell signaling and cycling-associated guanine nucleotide exchange factors (GEF). See product G3776 for RNA polymerase transcription and DNA or RNA biosynthesis applications.

Application

Guanosine 5′-triphosphate sodium salt hydrate has been used:

• as a component of the internal solution for astrocyte patch-clamp to monitor astrocyte calcium activity from mouse amygdala slices.
• in a solution for channel current recording in cell lines using a voltage-clamp technique.
• to prepare internal recording solution for injectoporation to deliver genes to mechanosensory hair cells.
• promoting the formation of G interface-mediated homodimers of human septin during the analysis of its oligomerization state by analytical size exclusion chromatography (SEC).
