ExoBrite™ STORM CD9 Antibody is designed for detecting the EV marker CD9 using stochastic optical reconstruction microscopy (STORM). Conjugated to optimized CF® Dyes for superior STORM performance, the antibody and its buffer are also specifically formulated for reliable detection of isolated EVs.
- Validated antibody for detecting EV marker CD9
- Available with excellent STORM dyes CF®498, CF®568, CF®583R, and CF®647Plus
- Proprietary buffer for enhanced signal-to-noise
- Available in 4 colors for FITC, Cy®3, Texas Red®, and Cy®5 channels
The most common proteins used as EV markers are CD9, CD63, and CD81, members of the tetraspanin family. These tetraspanins are broadly expressed on many cell types and can therefore be detected on many types of EVs, but their expression levels vary depending on the cell type of origin.
Superior performance for STORM imaging
Other commercially available antibodies for tetraspanin proteins CD9, CD63, and CD81 are generally not validated for isolated EVs or super-resolution imaging, and may require tedious optimization for your EV prep and staining protocol.
ExoBrite™ STORM Antibodies are powered by our industry-leading CF® Dyes for STORM. Available in CF®498, CF®568, CF®583R, and CF®647Plus, these dyes offer exceptional photochemical switching properties—delivering superior signal quality and image reconstruction for unmatched performance in STORM.
The labeled antibody was carefully selected and validated for robust detection of isolated EVs. In addition, the antibodies are provided in a proprietary buffer formulation for reduced antibody aggregation and brighter EV staining for optimal accuracy and signal-to-noise. ExoBrite™ STORM Antibodies are compatible with co-staining with other fluorescently labeled antibodies or for bead-bound EV staining protocols.
Cholera toxin subunit B (CTB) conjugated to high-performance CF® Dyes for STORM are also available, as well as tetraspanin antibodies optimized for detection of EVs by flow cytometry and western blotting.
