Product Description
CTB Conjugates with CF® Dyes for Super-Resolution dSTORM Imaging of EVs
ExoBrite™ STORM CTB EV Staining Kits are fluorescent cholera toxin subunit B (CTB) conjugates optimised for direct stochastic optical reconstruction microscopy (dSTORM) imaging of extracellular vesicles (EVs).
CTB binds with high affinity to GM1 gangliosides present in lipid rafts and EV membranes, making it a reliable probe for visualising EVs. Unlike traditional lipophilic dyes, ExoBrite™ STORM CTB stains show minimal background aggregation, ensuring accurate identification of purified or bead-bound EVs.
Incorporating CF® Dyes validated for STORM, these stains provide bright signal, low background, and superior single-molecule resolution. They are fully compatible with antibody co-staining, enabling multi-parameter EV characterisation at the nanoscale.
