RGAL‑45A is an affinity‑purified rabbit polyclonal antibody targeting β‑galactosidase, a widely used reporter enzyme in molecular biology. The purification process yields high‑specificity immunoglobulins that deliver strong, selective binding with minimal background. This antibody is well suited for Western blotting, ELISA, immunoprecipitation, and other assays requiring precise detection of β‑galactosidase. Produced by Immunology Consultants and supplied in a 1 mg format, RGAL‑45A is an essential reagent for researchers working with lacZ reporter systems or studying β‑galactosidase expression.
