This affinity‑purified goat antibody provides strong, specific detection of the C‑Myc epitope tag used in recombinant protein expression and purification. It performs reliably in ELISA, Western blotting, immunoprecipitation, and protein characterization workflows. GMYC‑45A offers low background, high affinity, and consistent lot‑to‑lot performance, making it a valuable reagent for laboratories monitoring C‑Myc–tagged constructs in research, production, and quality‑control environments.
