Product Overview
This rabbit polyclonal antibody targets CD27 antigen in human and mouse samples and is validated for Western blot and IHC. The predicted molecular weight is 29.1 kDa, and the supplier reports an observed band at about 55–60 kDa.
CD27 is a TNF receptor superfamily co-stimulatory receptor on T cells, NK cells and B cells that binds CD70. CD70–CD27 signaling supports T-cell activation, survival and memory formation, and CD27 is a commonly used marker for memory B cells and T-cell differentiation states.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
Samples with a confirmed band (WB): human Raji cells, human Ramos cells, human Daudi cells, mouse EL-4 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% 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 spleen 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 CD27 fragment (Ala20–Arg191), expressed in E. coli. Sequence identity with the mouse ortholog: 62.8%.
Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt places CD27 antigen in the cell membrane. Tissue expression noted by UniProt (human): Found in most T-lymphocytes. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
