Anti-CD9 Antibody

Designed for research workflows that require a well-validated tetraspanin marker, this primary reagent from Antibodies.com is supplied as a 50 µL liquid formulation in 1×TBS (pH 7.4) containing 1% BSA, 40% glycerol, and 0.05% sodium azide as preservative, ready for direct use in routine immunodetection protocols. The unconjugated recombinant rabbit monoclonal antibody targets CD9 (tetraspanin-29, p24) and is recommended for Western Blot (WB), Immunocytochemistry/Immunofluorescence (ICC/IF), Immunohistochemistry (IHC), and Flow Cytometry (FC), giving laboratories a single reagent that covers biochemical, imaging, and cell-surface phenotyping applications. Host species is rabbit and the clonality is monoclonal, with reactivity confirmed in human, mouse, and rat samples, making the antibody a practical choice for cross-species studies of platelet biology, exosome markers, and tetraspanin-mediated signalling. The glycerol-containing buffer preserves antibody activity during short-term refrigerated handling and supports standard freezing for longer-term storage, while the absence of a fluorophore or enzyme label allows researchers to pair it with their preferred secondary detection reagents.
