Product Overview
Clone 26S95 is a rabbit monoclonal antibody that recognizes high affinity copper uptake protein 1 (gene SLC31A1) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 21.1 kDa, and the supplier reports an observed band at about 29 kDa.
CTR1 (SLC31A1) is the main high-affinity copper importer at the plasma membrane. It brings Cu+ into cells and passes it to copper chaperones such as ATOX1, supplying copper for enzymes like cytochrome c oxidase and superoxide dismutase, and it has also been implicated in cellular uptake of platinum drugs such as cisplatin.

|---|
Samples with a confirmed band (WB): human HeLa cells, human HepG2 cells, human K562 cells, human Caco-2 cells, rat C6 cells, rat RH35 cells, mouse Neuro-2a cells, mouse HEPA1–6 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 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:1000, ECL detection.
Immunogen
Synthetic peptide based on the sequence of human CTR1/SLC31A1.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places high affinity copper uptake protein 1 in the cell membrane, early endosome membrane, recycling endosome membrane and apical cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
