RGST‑45B‑Z offers the same high‑quality biotin‑conjugated anti‑GST antibody as RGST‑45B but in a 0.1 mg format ideal for small‑scale experiments, pilot studies, or limited‑use applications. This reagent provides strong, selective binding to the GST tag and integrates seamlessly into streptavidin‑based detection workflows, including ELISA and Western blotting. Manufactured by Immunology Consultants, RGST‑45B‑Z is a cost‑efficient option for laboratories needing a smaller quantity of a sensitive, biotin‑labeled anti‑GST antibody without compromising performance.
