Product Overview
This rabbit polyclonal antibody recognizes P-selectin (gene SELP) in human samples and is validated for ELISA, IHC and Western blot. The predicted molecular weight is 90.8 kDa, and the supplier reports an observed band at about 140 kDa.
P-selectin (SELP, CD62P) is an adhesion molecule stored in platelet α-granules and endothelial Weibel-Palade bodies and moved to the cell surface upon activation. It binds PSGL-1 on leukocytes to start their rolling during inflammation and links platelets with leukocytes, and it is widely used as a platelet activation marker.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HEL cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 8% 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 tonsil 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 CD62P fragment (Trp42–Gly271), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 75.2% and 75.7%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt places P-selectin in the cell membrane. Tissue expression noted by UniProt (human): Stored in the alpha-granules of platelets and Weibel-Palade bodies of endothelial cells. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
