Product Overview
This rabbit polyclonal antibody recognizes tryptophan--tRNA ligase, cytoplasmic (gene WARS1) in human and mouse samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 53.2 kDa, and the supplier reports an observed band at about 55 kDa.
WARS1 is the cytoplasmic tryptophanyl-tRNA synthetase, which attaches tryptophan to its tRNA for protein synthesis. It is strongly induced by interferon-γ, and alternatively spliced or cleaved fragments (such as T2-TrpRS) inhibit angiogenesis. WARS1 is studied in translation, immunity and vascular biology.

Samples with a confirmed band (WB): human HepG2 cells, human HeLa cells, human Jurkat cells, human MCF-7 cells, mouse brain tissue, mouse lung 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, 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 adrenocortical adenoma 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.

Samples with confirmed staining (ICC/IF): U87 cells.
Samples with a confirmed signal (flow cytometry): THP-1 cells.
Immunogen
Recombinant human WRS/WARS1 fragment (Glu5–Lys369), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt places tryptophan--tRNA ligase, cytoplasmic in the cytoplasm. 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).
