Anti-eRF3a (D128) Antibody

Raised in rabbit against an epitope centred on residue D128 of eukaryotic peptide chain release factor subunit 3a, this polyclonal IgG antibody is supplied by Antibodies.com as a 50 µL liquid preparation at approximately 1 mg/mL in phosphate-buffered saline (PBS) containing 0.05% sodium azide, pH ~7.2. The unconjugated reagent is validated for western blotting and immunohistochemistry across human, mouse and rat samples and is intended for research use only. The target, also known as GSPT1, eRF3a, ETF3A or GST1, is a GTP-binding subunit of the eRF3 release factor complex, and the antibody provides a robust polyclonal response suitable for routine detection of the endogenous protein. Aliquoting is recommended to avoid repeated freeze-thaw cycles, and the product should be stored refrigerated for short-term use or frozen for long-term stability.
