Product Overview
This rabbit polyclonal antibody recognizes thy-1 membrane glycoprotein (gene THY1) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 17.9 kDa, and the supplier reports an observed band at about 22 kDa.
Thy-1 (THY1, CD90) is a small GPI-anchored glycoprotein of the immunoglobulin superfamily found on the surface of neurons, thymocytes, T cells in mice, fibroblasts and some stem cells. It takes part in cell–cell and cell–matrix interactions, including in the nervous system. CD90 is widely used as a marker for T cells in mice, mesenchymal stromal cells and hematopoietic stem cells.

Validated Applications
| Western blot | 0.1–0.25 µg/mL (Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human U251 cells, rat brain tissue, rat thymus tissue, mouse brain tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 12% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.25 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human brain 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 CD90/Thy1 fragment (Gln20–His111), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places thy-1 membrane glycoprotein in the cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
