Thermo Scientific™ CaptureSelect™ Biotin Anti-CD63 Conjugate

This conjugate allows you to detect, quantitate, and characterize CD63-expressing extracellular vesicles (EVs) like exosomes. Together with CaptureSelect HRP Anti-CD63 Conjugate (Cat. No. 7303992100), a sandwich ELISA can be set up to detect and quantitate CD63 expressing EVs.

Applications for CaptureSelect Biotin Anti-CD63 Conjugate include sandwich ELISA, Gyrolab™-based immunoassays, immunoprecipitation, and sample prep purification using streptavidin-coupled Dynabeads or MSIA Streptavidin D.A.R.T.S and label-free detection platforms such as those based on surface plasmon resonance (SPR) and bio-layer interferometry (BLI). For more information see our Biotin Application Guide.

For detection of a broad variety of EVs and exosomes that originate from different cell types and secretion pathways, such as those of endosomal (CD63-enriched, CD9+, or CD81+) or ectosomal (CD63 low, CD9+ and CD81+) origin, we also offer CaptureSelect Biotin and HRP anti-CD81 conjugates and CaptureSelect Biotin and HRP anti-CD9 conjugates.

Animal origin statement

CaptureSelect products contain affinity ligands based on recombinant single-domain antibody fragments (VHH) created by a proprietary technology. The VHH affinity ligand is a 12–15 kDa fragment comprising the three complementarity-determining regions (CDRs) that form the antigen-binding domain, efficiently produced in yeast Saccharomyces cerevisiae by a production process free of any animal components (Animal Origin-Free).
