Product Overview
This rabbit polyclonal antibody recognizes alanine--tRNA ligase, cytoplasmic (gene AARS1) in human samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 106.8 kDa, and the supplier reports an observed band at about 107 kDa.
Alanyl-tRNA synthetase 1 (AARS1) charges tRNA(Ala) with alanine in the cytoplasm and uses a separate editing domain to remove wrongly attached amino acids, protecting the accuracy of protein synthesis. Mutations in AARS1 are linked to inherited neuropathies such as Charcot-Marie-Tooth disease.

Immunogen
Recombinant human AlaRS/AARS1 fragment (Arg729–Asn968), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places alanine--tRNA ligase, cytoplasmic in the cytoplasm and nucleus. 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).
