Good Start VeriYou CF and SMA Test

Oct 13, 2016

Good Start Genetics has launched its VeriYou CR and SMA test, a saliva-based screening test for two of the most common inherited genetic disorders: cystic fibrosis and spinal muscular atrophy. Patients send saliva samples to the company's CLIA-certified and CAP-accredited laboratory, where the samples are screened for 591 genetic variants. While patients can submit the kits themselves, testing must be approved by a physician. Results are delivered securely and interactively online with educational information including the ability to address follow-up questions with physicians directly and to connect with genetic counselors, the company said.

LabCorp ADAMTS13 Test

Laboratory Corporation of America began offering the ADAMTS13 test for a rare life-threatening blood-clotting disorder. The test distinguishes diseases characterized by acute thrombotic microangiopathy (TMA), a relatively rare syndrome in which small blood vessels develop blood clots. The test can provide faster and more accurate results, compared to other tests, to rule in or out the diagnosis of thrombotic thrombocytopenia purpura, a condition that can cuase TMA, and to support decisions whether to start patients on certain therapies, LabCorp said. The test is run on liquid chromatography-tandem mass spectrometry technology.

Quest Diagnostics QHerit Screening Service

Quest Diagnostic launched QHerit, a genetic screening service that tells individuals their risk of passing on heritable disorders to future generations. The QHerit Pan-Ethnic Expanded Carrier Screen provides information for 22 heritable diseases cited under new screening guidelines issued earlier this year by the American College of Gynecology. In addition to more well-known heritable disorders such as cystic fibrosis and sickle cell disease, QHerit also identifies lesser-known mutations associated with Joubert Syndrome 2 and fragile X syndrome. It also screens for spinal muscular atrophy and includes the evaluation of hemoglobinopathies.

Agilent Technologies SureSelectXT HS NGS Library Prep Solution

Agilent Technologies has launched the Agilent SureSelectXT HS, its newest next-generation sequencing library prep solution. SureSelectXT HS provides total workflow management for laboratories, from QC to target enrichment, analysis, and interpretation, the company said. It's optimized for labs with a requirement to sequence DNA from formalin-fixed paraffin-embedded samples, which may have degraded over time. SureSelectXT HS also incorporates molecular barcodes, improving overall precision and producing high complexity libraries on a broad range of tissue types and low- and high-quality FFPE samples. SureSelectXT HS libraries require as little as 10 ng of starting DNA, and use molecular barcodes to assist error correction. Additionally, faster and more efficient processing with master-mixed reagents that require less hands-on time, coupled with a 90-minute hybridization enables labs to now move from sample to sequencer in a single day.

Fluidigm Advanta Immuno-Oncology Gene Expression Assay

Fluidigm has launhced the Advanta Immuno-Oncology Gene Expression Assay, a research-use-only qPCR assay that enables interrogation of tumor immunobiology using Fluidigm's microfluidic technology. Designed for use with the Biomark HD system, the assay detects 170 gene expression markers involved in checkpoint therapeutic response from FFPE and fresh frozen tumor samples. The assay can analyze biomarkers across defined T cell subsets, immune regulation, immune cell fate, cytokines, chemokines, and more, and can enable translational researchers to accelerate the development of checkpoint immunotherapies and to identify predictive biomarker signatures for therapeutic response.

Fluidigm said that the product is available as a two-panel set. The first panel includes 91 key markers of tumor immune response that were previously shown in a multicenter international clinical trial to inform tumor progression and checkpoint therapeutic response. The second panel includes 74 additional immuno-oncology markers and 17 open assay inlets for additional customization. Both panels contain the same five reference genes and can be purchased and used together or separately.

Empirical Bioscience 2X qPCR Probe Master Mix

Empirical Bioscience has released 2X qPCR Probe Master Mix for probe-based quantitative PCR applications. This new product is for real-time evaluation of DNA using fluorescent probe-based detection. It contains FlashTaq HotStart DNA polymerase, a chemically modified Taq DNA polymerase that remains inactive at room temperature but becomes activated after 2 minutes at 95° C. The master mix also contains dNTPs, MgCL2, and optimized buffer for fast, efficient qPCR. It has been optimized for use with hydrolysis-based probes such as TaqMan, but is also suitable with other probe-based detection systems. The mix is available in multiple versions for various applications including bulk and custom volumes for commercial and biotech.

Seraseq Circulating Tumor DNA v2 Reference Materials

SeraCare Life Sciences has launched a new set of ctDNA reference materials to aid development and validation of liquid biopsy assays. The new Seraseq Circulating Tumor DNA v2 reference materials were produced using a unique technology that produces a DNA fragment size-distribution which closely mimics native cfDNA, while decreasing DNA damage relative to ultrasonicated material, the company said.

The new product requires no special workflow considerations to generate informative data, and contains 40 somatic mutations, including important targets like BRAF V600E, KRAS G12D, and various EGFR alterations. Variants are present against a single well-characterized genomic background across a range of allele frequencies down to 0.125 percent, which ensures utility for assays with different limits of detection.

Li-Cor Biosciences D-DiGit Gel Scanner

Li-Cor Biosciences has launched the LED-based D-DiGit Gel Scanner, designed to help researchers eliminate the risk of ethidium bromide exposure and workspace contamination from their nucleic acid gel analysis experiments. The new system enables safe and convenient detection of DNA and RNA samples stained with fluorescent safe stains, like SYBR Safe, which are sensitive and environmentally friendly alternatives to ethidium bromide. Added either during gel preparation, or as a post-electrophoresis stain, safe stains eliminate the need for hazardous disposal and hassles associated with ethidium bromide. The D-DiGit improves protocol efficiency by consolidating nucleic acid analysis on a single system dedicated to high-sensitivity gel imaging. The scanner provides a large scan area to visualize most medium and larger format gels. Nucleic acid band extraction and imaging can be performed directly on the scan surface, the company said.
