Product Overview
Clone 5F5 is a mouse monoclonal antibody that recognizes elongation factor 2 (gene EEF2) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 95.3 kDa, and the supplier reports an observed band at about 95 kDa.
Elongation factor 2 (EEF2) is a GTPase that moves the ribosome along mRNA after each peptide bond is formed during translation. Its activity is switched off by eEF2 kinase phosphorylation, and it is a well-known target of diphtheria toxin.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Huma) |
| Immunocytochemistry / Immunofluorescence | 5 µg/mL (Human) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human, Mouse, Rat) |
Samples with a confirmed band (WB): human HeLa cells, human HepG2 cells, human Jurkat cells, human U2OS cells, rat PC-12 cells, mouse NIH/3T3 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, 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): human breast cancer tissue, human rectal cancer tissue, human liver 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 EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): HepG2 cells.
Samples with a confirmed signal (flow cytometry): HEPA1–6 cells, HL-60 cells, NRK cells.
Immunogen
Synthetic peptide from the N-terminal region of human EEF2/Elongation factor 2. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places elongation factor 2 in the cytoplasm and nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
