Product Overview
This rabbit polyclonal antibody recognizes antigen peptide transporter 2 (gene TAP2) in human samples and is validated for Western blot. The predicted molecular weight is 75.7 kDa, and the supplier reports an observed band at about 87 kDa.
TAP2 pairs with TAP1 to form the transporter associated with antigen processing, an ATP-driven ABC transporter of the ER membrane. The heterodimer moves proteasome-generated peptides from the cytosol into the ER for loading onto MHC class I, so it is essential for presenting intracellular antigens to CD8+ T cells.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human) |
|---|
Samples with a confirmed band (WB): HeLa 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, 40 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.
Immunogen
Synthetic peptide from the C-terminal region of human TAP2. It differs from the mouse sequence at five residues and from the rat sequence at six residues.
Reactivity Notes
The supplier lists reactivity with human. UniProt places antigen peptide transporter 2 in the endoplasmic reticulum membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
