Product Overview
This rabbit polyclonal antibody recognizes transmembrane protein 255B (gene Tmem255b) in mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 39.4 kDa, and the supplier reports an observed band at about 45 kDa.
Tmem255b is a mouse transmembrane protein of the TMEM255 family. Its biological function has not been fully characterized.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Mouse) |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL (Rat) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): mouse heart tissue, mouse testis tissue, mouse lung 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 lung tissue, rat intestine 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 mouse Tmem255b fragment (Gln196–Leu240), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt places transmembrane protein 255B in the membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
