WebSynapto-pHluorin is a genetically encoded optical indicator of vesicle release and recycling. It is used in neuroscience to study transmitter release. It consists of a pH-sensitive form of green fluorescent protein (GFP) fused to the luminal side of a vesicle-associated membrane protein (VAMP).
WebKeima is a mammalian dual-emission autophagy biosensor. Its resistance to lysosomal proteases is key to its pH-dependent fluorescence. In neutral environments, dimeric Keima is excited at 440 nm and in acidic environments at 586 nm. Regardless of excitation wavelength, Keima emits at 620 nm. WebGFP is sensitive to acid. The chromophore of GFP can exist in a protonated and a deprotonated state (Tsien, 1998). The deprotonated state has an absorbance maximum …
Webprofiles of specific GFP variants are sensitive to pH changes [3-6]. Using a directed mutagenesis approach in E. coli, Rothman and coworkers [3] developed two, pH-sensitive GFP variants, termed ecliptic- and ratiometric pHluorin, each containing clusters of mutations that direct pH sen-sitivity.
