Scantibodies Heterophilic Blocking Reagent (HBR)


The existence of heterophilic antibodies and their potential for causing interference in immunoassays has been known for many years.

The increasing use of the susceptible 2-site immunometric (“sandwich”) assay format has led to growing concern over the problem, and because of this Scantibodies Laboratory has developed a unique heterophilic blocking reagent (HBR) that minimizes the occurrence of heterophilic antibody interference.
