This compact 0.1 mg format of the biotin‑conjugated anti‑HA tag antibody provides the same high‑quality performance as the full‑size version, optimized for labs needing smaller quantities or pilot‑scale testing. The biotin label enables sensitive detection through streptavidin‑HRP, streptavidin‑AP, or streptavidin‑fluorophore systems, making it suitable for ELISA, blotting, and imaging workflows. Manufactured by Immunology Consultants, the antibody offers strong HA epitope recognition with minimal background. Its smaller size is ideal for assay development, limited‑sample projects, or researchers evaluating biotin‑based detection strategies without committing to a full‑scale reagent volume.
