Product Overview
This rabbit polyclonal antibody detects UL16-binding protein 1 (gene ULBP1) in human, mouse and rat samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 28.0 kDa, and the supplier reports an observed band at about 28 kDa.
ULBP1 is a cell-surface protein that serves as a ligand for NKG2D, an activating receptor on natural killer cells and some T cells. It is usually low on healthy cells but can be induced by stress, infection or transformation, allowing NK cells to recognize and kill such cells. It is studied in tumor immunology and antiviral immunity.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): rat lung tissue, mouse brain tissue, mouse heart tissue, mouse lung tissue, human Raji 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 mammary cancer 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 a confirmed signal (flow cytometry): PC-3 cells.
Immunogen
Recombinant human ULBP1 fragment (Trp27–Lys209), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places UL16-binding protein 1 in the cell membrane and endoplasmic reticulum. Tissue expression noted by UniProt (human): Expressed in T-cells, B-cells, erythroleukemia cell lines and in a wide range of tissues including heart, brain, lung, liver, testis, lymph node, thymus, tonsil and bone marrow. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
