Description

Description

  • Cholera toxin B subunit (CT-B) attaches to cells by binding to ganglioside GM1, making it powerful tool for retrograde labeling of neurons
  • This tracer has been used in variety of applications, including tracing of rat forebrain afferents, projections of the parabrachial region, and neurons of the urinary bladder wall
  • When used in neuronal tracing applications, CT-B is typically introduced by pressure injection or by iontophoretic injection into neural tissue
  • At neutral pH, 11.4 kDa B subunit exists as 57 kDa pentamer
  • Lyophilized product can be dissolved in buffer (e.g., PBS) for use
  • More recently, researchers have found that CT-B can be used as marker for lipid rafts, which are membrane microdomains enriched in cholesterol and sphingolipids thought to be important in cell signaling
  • For lipid raft staining, cells are first incubated with fluorescent CT-B, then an anti-CT-B antibody is added to crosslink the CT-B in the lipid rafts into distinct patches on the plasma membrane
  • These patches are easily visualized by fluorescence microscopy

  • Label (Ex/Em): Alexa Fluor™ 555 (555/565nm)
  • At neutral pH, the 11.4 kDa B subunit exists as a 57 kDa pentamer
