A Successful Duo for Accurate, Speedy, and Economical SNP Genotyping

Posted on Thu, Jan 08, 2015 @ 11:30 AM

Single Nucleotide Polymorphisms (SNPs) have been widely studied for over 15 years, and have applications in forensics, disease susceptibility studies, pharmacogenomic and other personalized medicine applications, crop and livestock breeding programs. Numerous genetic methods and companion platforms have been developed for SNP detection encompassing DNA sequencing, microarrays, mass spec, and PCR based techniques. For high sample throughput applications, PCR analysis has emerged as the method of choice for rapid targeted SNP analysis, facilitated by new platforms and reagent cost improvements. On October 30, 2014, Biosearch Technologies sponsored a webinar showcasing the utility of the BHQplus® probe technology for qPCR based SNP analysis. Presenter Cassie Keppel, Laboratory Operations Manager at Douglas Scientific, shared some compelling data showing the accurate and economical utility behind the use of Biosearch’s BHQplus probes on Douglas Scientific’s Array Tape® platform. In this article, we highlight some of Cassie’s findings on the dramatic cost-savings that the BHQplus probe and Array Tape platform combination offers.

Black Hole Scorpion® Primers - Killer probes for qPCR

Posted on Wed, Mar 24, 2010 @ 08:57 AM

A "Referral from the Doctor" Blog Article-  

Scorpions®Primers are dual-labeled FRET probes that combine a Molecular Beacon®-like probe structure and a PCR primer element in a single oligonucleotide, allowing for specific target amplification and advanced target detection through a unimolecular or single oligonucleotide driven mechanism.

Structure

Q. What parts are similar to dual-labeled Black Hole Quencher® (BHQ) probes?
A BHQ dye and a 5'-fluorophore covalently bound to the oligonucleotide termini.

Labeling Oligos with Internal BHQ Dyes

Posted on Tue, Sep 29, 2009 @ 08:16 AM

 

When to use an internal Black Hole Quencher (BHQ) label in a fluorescence-quenched probe for real-time qPCR.

When the sequence length of your probe is 30 bases or shorter, we recommend selecting a conventional BHQ label for the 3' end of your probe. We have noticed, however, that probe lengths longer than 30 bases exhibit high background noise and are frequently nonfunctional. They are too long for efficient FRET quenching, a mechanism that is highly dependent upon the distance between the fluorophore and quencher. A shorter average distance between fluorophore and quencher is optimal for a FRET quenching environment, which is common in real-time qPCR experiments.

Salt-Free Primer Pair Option Now Available

Posted on Tue, Sep 22, 2009 @ 08:08 AM

Biosearch Technologies will now be offering the option of salt-free primer pairs for purchase with any probe order. A more affordable option for real-time qPCR, these primers offer a higher yield at a faster turnaround time in comparison to cartridge-purified primers.

We have done extensive research to show that the difference in purity specifications does not compromise the quality or performance in assays using the salt-free primer pairs instead of the cartridge purified primer pairs. You can review the Biosearch-conducted purification study by downloading this report.
