This product is a horseradish peroxidase (HRP)-directly conjugated rabbit polyclonal antibody against the His tag, recognizing polyhistidine motifs such as 6×His. The His-Tag is one of the most widely used tags in recombinant protein purification, enabling rapid purification via immobilized metal ion affinity chromatography (IMAC). The HRP direct conjugation makes this antibody particularly suitable for Western Blot (WB), allowing fast and sensitive detection of His-tagged fusion proteins while eliminating the need for secondary antibody incubation, thus streamlining the experimental procedure.
