MemGlow NR4A is a solvatochromic photostable plasma membrane-targeting dye with on/off switching that has been optimized for Super Resolution Point Accumulation for Imaging in Nanoscale Topography (SR-PAINT). Upon binding with a plasma membrane in a predominant liquid ordered (LO) phase NR4A 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.
NR4A Membrane Polarity Probe Product Functions (MG06)：
The NR4A Membrane Polarity Probe is the first probe that enables nanoscale cartography of the lipid order exclusively at the surface of live cells.
The NR4A Membrane Polarity Probe reveals nanoscopic protrusions and invaginations of lower Lipid Order in Plasma Membranes
High Specificity helps unveil rich nanoscale structural features of the plasma membrane
Weak Binders allow for better tracking of turn on events thanks to continuous flow exchange between the probe and membrane
** 2 nmol of MemGlow will produce a 20μM stock solution when reconstituted with 100 μl of anhydrous DMSO
