MemGlow NR12S is a solvatochromic photostable plasma membrane-targeting dye. Upon binding with a plasma membrane in a predominant liquid ordered (LO) phase NR12S exhibits a 45-50 nm wavelength shift relative to liquid disordered (LD) phase enabling investigators to examine the nanoscale distribution of local chemical polarity in plasma membranes. NR12S can also be used to label the plasma membrane for conventional fluorescence microscopy imaging.
