Product Overview
This rabbit polyclonal antibody targets phosphatidylethanolamine-binding protein 1 (gene PEBP1) in human and mouse samples and is validated for flow cytometry, IHC and Western blot. The predicted molecular weight is 21.1 kDa, and the supplier reports an observed band at about 21 kDa.
PEBP1, also called RKIP (Raf kinase inhibitor protein), is a small conserved protein that binds phosphatidylethanolamine and nucleotides. It restrains the RAF1-MEK-ERK pathway by preventing RAF1 from activating MEK, and its N-terminal peptide HCNP can stimulate choline acetyltransferase in cholinergic neurons. It is studied in MAPK signaling and cancer.

Samples with a confirmed band (WB): human HeLa cells, human MCF-7 cells, human HepG2 cells, human 293T cells, mouse testis.
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.

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 citrate buffer (pH 6).
Samples with a confirmed signal (flow cytometry): HepG2 cells.
Immunogen
Synthetic peptide from the C-terminal region of human PBP. Sequence identity with the mouse and rat orthologs: 87.5% and 80%, respectively.
Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt places phosphatidylethanolamine-binding protein 1 in the cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
