Product Overview
Clone 25S21 is a rabbit monoclonal antibody that recognizes sphingosine 1-phosphate receptor 3 (gene S1PR3) in human samples and is validated for Western blot, IHC and ICC/IF. The predicted molecular weight is 42.3 kDa, and the supplier reports an observed band at about 42 kDa.
S1PR3 (also known as EDG3) is a G protein-coupled receptor for sphingosine 1-phosphate that can couple to several G protein classes. It influences cell survival, proliferation and migration, and it is studied in vascular biology, inflammation and fibrosis.

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 1:1000 overnight at 4 °C, HRP-conjugated secondary antibody at 1:500, ECL detection.
Immunogen
Synthetic peptide based on the sequence of human EDG3.
Reactivity Notes
The supplier lists reactivity with human. UniProt places sphingosine 1-phosphate receptor 3 in the cell membrane. Tissue expression noted by UniProt (human): Expressed in all tissues, but most abundantly in heart, placenta, kidney, and liver. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
