How do I label the cell membrane?

Posted November 19, 2022


The cell membrane can be labeled using Lipophilic Tracers, Fluorescently Labeled Lectins, and Fluorescent Probes. 

  • Lipophilic Tracers used to label the cell membrane include dialkylcarbocyanines DiO, DiI, DiA, DiD, DiR and DiS
  • Fluorescent Wheat Germ agglutinin (WGA) is a Fluorescently Labeled Lectin used extensively to label the cell membrane. 
  • Fluorescent probes of FM4-64, LRB-PE, DiIC12, DiIC18, DiD, BD-SM and Laurdan are most widely used to label cell membrane.
