Product Overview
This rabbit polyclonal antibody detects tetraspanin-1 (gene Tspan1) in rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 26.5 kDa, and the supplier reports an observed band at about 28–30 kDa.
In rat, tetraspanin-1 (Tspan1) is a four-pass membrane protein that helps organize tetraspanin-enriched microdomains, platforms for clustering receptors and signaling molecules. Through these domains it influences cell adhesion, migration and protein trafficking, and it has been reported to support NGF signaling through TrkA during neuronal differentiation.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Rat) |

Samples with a confirmed band (WB): rat small intestine tissue.
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, 50 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): rat stomach 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).
Samples with confirmed staining (ICC/IF): rat stomach tissue.
Samples with a confirmed signal (flow cytometry): RH35 cells.
Immunogen
Recombinant rat Tspan1 fragment (Ala125–Ala212), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with rat. UniProt places tetraspanin-1 in the cell membrane and lysosome membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
