Product Overview
This rabbit polyclonal antibody recognizes peflin (gene PEF1) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 30.4 kDa, and the supplier reports an observed band at about 30 kDa.
Peflin (PEF1) is a penta-EF-hand calcium-binding protein that forms a heterodimer with ALG-2 (PDCD6). Together they act as a Ca2+-regulated adaptor for the CUL3-KLHL12 ubiquitin ligase and the COPII protein SEC31, influencing ER-to-Golgi export of large cargo such as collagen, although whether peflin promotes or restrains this step is still debated.

|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HEK293 cells, human placenta tissue, human PC-3 cells, human U-87MG cells, human U-937 cells, human HepG2 cells, human A431 cells, human U2OS cells, rat lung tissue, rat testicular tissue, mouse lung tissue, mouse testicular 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 1:10000, ECL detection.
Samples with confirmed staining (IHC): mouse testis tissue, rat testis tissue, human colon cancer tissue, human lung cancer 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 citrate buffer (pH 6).
Immunogen
Recombinant human PEF1 fragment (Arg170–Leu284), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places peflin in the cytoplasm, endoplasmic reticulum and membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
