Biosearch Technologies Responds to China Influenza H7N9 Outbreak by Providing H7N9 Detection Panel

NOVATO, CA (MONDAY, APRIL 15, 2013) – Biosearch Technologies, Inc. (Biosearch) announced today that the company has implemented a rapid response to the current outbreak of Avian Influenza Virus A (H7N9) in China. Biosearch is ready to provide to the scientific community on-demand, rapid synthesis of real-time qPCR probes and primers composing the H7N9 detection panel recently developed and published on 8 April by the World Health Organization (WHO) Collaborating Center for Reference and Research on Influenza in Beijing, China. WHO lists FAM-BHQ® probes as crucial reagents in their protocol named, “Real-time RT-PCR Protocol for the Detection of A(H7N9) Influenza Virus,” which is available for download at:

BHQ (Black Hole Quencher®) dye technology has a proven performance record as the critical component in the detection and characterization of 2009 Influenza A (H1N1). As the inventor of the BHQ dyes, Biosearch is directing significant resources to providing fast turnaround time in the production of H7N9 ValuPanel Reagents* to ensure that scientists in laboratories worldwide have a reliable, quality source for monitoring the incidence of this influenza outbreak. “Biosearch is prepared as we were during the 2009 H1N1 pandemic to supply the H7N9 signatures to scientists worldwide,” says Marc Beal, Director of Corporate Development at Biosearch Technologies. “Our recent acquisition of DNA Technology A/S (Århus, Denmark) will also enable Biosearch to effectively meet European demand.”

Biosearch will prepare the following assay components:

  • Universal InfA probe and primers to detect all strains of influenza A;
  • H7 and N9 probe and primers to subtype the novel strain of avian influenza; and,
  • RNaseP probe and primers as a form of positive control
