Biosearch Technologies - Provider of Probe & Primer Reagents used in Swine Influenza A/H1N1 Viral Strains

NOVATO, CA (Thursday, May 14, 2009) – Biosearch Technologies, Inc. (Biosearch) today announced that the company has responded to the swine influenza pandemic, also known as 2009 H1N1, by offering to the public the rapid custom synthesis of all research use only (RUO) oligonucleotide probes and primers composing the swine flu detection panel recently developed and disclosed by the CDC. According to the CDC protocol of real-time PCR for detecting swine influenza A/H1N1 (CDC REF. #I-007-05), which is available to the public at the World Health Organization’s website:, FAM-BHQ® probes are key components in the Swine Influenza Virus Real-time RT-PCR Detection Panel (Swine Flu Test Kit).

As the inventors of the BHQ® (Black Hole Quencher®) dye technology integral to the performance of the swine flu probes, Biosearch is putting all effort behind producing these probes and primers to ensure that laboratories around the world can reliably access these important reagents to amplify and probe for swine influenza. “In view of the seriousness, of the recent AH1N1 pandemic, Biosearch is devoting its considerable expertise and resources to the manufacture of influenza-related probes and primers,” comments Ron Cook, President and CEO of Biosearch Technologies, “And, in anticipation of future events of this kind, we are expanding our manufacturing infrastructure to allow ultra rapid scale up and delivery of any oligo component that may be required for assays of new subtypes.”

Biosearch will, upon customer request, prepare custom probes and primers for the following assays: InfA probe and primers to detect all universal strains of influenza A; swInfA probe and primers to detect all strains of swine influenza A; swH1 probe and primers to detect all strains of swine influenza H1; and RnaseP probe and primers as a form of positive control. If your research requires oligos besides swine flu probes and primers, those too, will be prepared upon request. All such probe and primers are available to the public for RUO purposes.
