Asuragen Launches New Kit to Enable Broader Coverage of Gene Variants Linked to Cystic Fibrosis

CFTR testing kit with streamlined workflow delivers reliable results in less than five hours

MINNEAPOLIS, Nov. 8, 2021 /PRNewswire/ -- Bio-Techne Corporation (NASDAQ:TECH) today announced that Asuragen, Inc., a Bio-Techne brand, has launched a new kit to detect pathogenic variants in the CFTR gene. The AmplideX^® PCR/CE CFTR Kit, intended for research use only, provides broader coverage of the diverse U.S. population^1,2 than any other commercially available, targeted CFTR testing assay.

Cystic fibrosis is a life-limiting, autosomal recessive disease caused by variants in the CFTR gene. Many people with cystic fibrosis experience problems with their lungs, including serious infections, limited function, and long-term damage.

While much is known about variants associated with cystic fibrosis, the vast majority of that information came from studies of people of European descent. As a result, screening and diagnostic tests, as well as research-use assays, are more likely to detect pathogenic variants in individuals of European descent and less likely to detect them in individuals with non-European ancestry³.

"We are committed to ensuring that our Asuragen kits consistently deliver the most reliable information across all populations. To that end, we are proud to launch the new AmplideX PCR/CE CFTR Kit, which incorporates variants from the latest large-scale studies of diverse populations to provide significantly broader coverage," said Kim Kelderman, President, Diagnostics and Genomics Segment.

Because it includes variants identified in recent population genomics studies, the AmplideX PCR/CE CFTR Kit is designed to detect approximately 93% of CFTR pathogenic variants⁴ observed in the U.S. population, providing more reliable variant detection regardless of ancestry. It can identify a broad range of variant types, including copy number variants, single tandem repeats, single nucleotide polymorphisms, insertions, and deletions. The kit can also resolve variant zygosity.

The assay uses a simple, streamlined, and scalable approach to deliver results in less than five hours with fewer hands-on steps than other CFTR assays. It is optimized for use on commonly used PCR and capillary electrophoresis laboratory equipment. The assay also includes push-button data analysis software and shares a common workflow with other assays in the AmplideX product portfolio for easy implementation. Finally, the AmplideX PCR/CE CFTR Kit can also combine with Asuragen's AmplideX^® PCR/CE FMR1 Kit and AmplideX^® PCR/CE SMN1/2 Plus Kit to provide the first-ever same-platform assay solution for this trio of the most prevalent and commonly analyzed carrier genes.
