Product Overview
This rabbit polyclonal antibody targets RNA-binding protein FUS in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 53.4 kDa, and the supplier reports an observed band at about 70 kDa.
FUS is a nuclear DNA/RNA-binding protein of the FET family that takes part in transcription, splicing, mRNA transport and the DNA damage response. It has a low-complexity domain that can drive liquid–liquid phase separation. Mutations in FUS cause some forms of amyotrophic lateral sclerosis (ALS), and FUS inclusions are seen in a subset of frontotemporal lobar degeneration.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human, Mouse, Rat) |

Samples with a confirmed band (WB): human HeLa cells, human K562 cells, human 293T cells, human Caco-2 cells, human Jurkat cells, human HL-60 cells, human HepG2 cells, human SH-SY5Y cells, rat brain tissue, 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, 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 rectal cancer tissue, mouse colon tissue, rat colon 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): A431 cells.
Samples with a confirmed signal (flow cytometry): ANA-1 cells, U87 cells.
Immunogen
Synthetic peptide from the middle region of human TLS/FUS. The peptide sequence is conserved in mouse.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places RNA-binding protein FUS in the nucleus. Tissue expression noted by UniProt (human): Ubiquitous. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
