Product Overview
Clone 23W83 is a rabbit monoclonal antibody that recognizes tryptophan--tRNA ligase, cytoplasmic (gene WARS1) in human, mouse and rat samples and is validated for Western blot, IHC and flow cytometry. The predicted molecular weight is 53.2 kDa, and the supplier reports an observed band at about 53 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.

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).
