Product Overview
This rabbit polyclonal antibody recognizes CD63 antigen in human samples and is validated for IHC and Western blot. The predicted molecular weight is 25.6 kDa, and the supplier reports an observed band at about 30–60 kDa.
CD63 is a tetraspanin found in late endosomes, lysosomes and multivesicular bodies, and on the cell surface. It is enriched on exosomes, where it is one of the most widely used markers, and it also serves as a marker of basophil and platelet activation.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
Samples with a confirmed band (WB): human MDA-MB-453 cells, human U87 cells, human HL-60 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human bladder urothelial carcinoma tissue, human spleen tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human CD63 fragment (Glu97–Met238), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 74% and 73%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt places CD63 antigen in the cell membrane, lysosome membrane, late endosome membrane and endosome. Tissue expression noted by UniProt (human): Detected in platelets (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
