Web1 dec. 2024 · Measured background radiation spectrum for the LYSO(Ce) scintillator. 2.1.4. Experimental efficiency. Photon detection efficiency is a key factor when carrying out accurate quantitative gamma-ray spectrometry. It depends on detector properties and counting geometry (source–detector distance and solid angle subtended by the detector). WebProduct Description. LysoView™ dyes are useful for staining lysosomes in live cells. No-wash, fluorescent staining of lysosomes in live cells. Non-toxic for real-time live-cell imaging. Lower background than LysoTracker® dyes. Dye options for super-resolution imaging. Color choices from blue to far-red, plus a unique NIR dye.
