MM 4-64 Fixable Membrane Stain

• Selective Membrane Labeling: Strong, localized fluorescence upon plasma membrane binding.
• Rapid, Reversible Binding: Ideal for real-time dynamic imaging studies.
• Fixation-Compatible: Compatible with aldehyde fixation for staining preservation.
• Neuroscientific Application: Ideal for active neuron detection and vesicle cycling studies.

MM4-64 Fixable Membrane Stain is a lipophilic probe optimized for selective plasma membrane labeling. In aqueous solution, it exhibits minimal fluorescence; however, upon binding to the outer leaflet of the plasma membrane, it produces robust fluorescence, enabling precise and reliable membrane visualization. The binding kinetics are both rapid and reversible, supporting its use in aldehyde-based fixation protocols without compromising staining integrity. Furthermore, MM4-64 Fixable Membrane Stain is particularly valuable in neuroscientific applications for identifying active neurons and examining mechanisms involved in activity-dependent vesicle cycling.
