Samplix Xdrop Services

Danish company Samplix has launched a comprehensive service program granting laboratories access to its Xdrop technology for complex genomic research including gap closing, sequencing of repeat elements, viral insertion site detection, revealing unintended CRISPR edits, and more. Xdrop enriches genomic regions longer than 100 kb from as little as 1 ng of human genomic DNA and with single-molecule resolution. It requires knowledge of only a short sequence within or flanking the target region for efficient target selection. Following targeted selection, multiple displacement amplification is applied to single DNA molecules compartmentalized in droplets. This ensures unbiased amplification of large DNA fragments that are representative of the target variation in the original sample. The output is ready for any short-read or long-read sequencing platform, the company said.

Swift Biosciences SARS-CoV-2 Research Panel

Swift Biosciences has released a research-use targeted sequencing panel for SARS-CoV-2. The amplicon-based multiplex panel targets the full 30 kb viral genome in a single tube, two-hour workflow with two rounds of PCR. More than three hundred primer pairs help increase sensitivity and specificity due to the higher probability of amplifying limited quantities of viral template material, as does the ability to use sequencing to confirm that reads are mappable to SARS-CoV-2 instead of similar coronaviruses or pathogens, the company said. Swift's workflow also adds sequencing adapters directly without the need for a secondary library construction.

Cartana In Situ Sequencing Reagent Kits

Cartana has launched a new range of in situ sequencing reagent kits designed to increase the efficiency and enable ISS on virtually any tissue sample. The new kits contain improved probing and sequencing technologies and come with easy-to-follow protocols for library preparation and sequencing. The HS Library Preparation Kit is used to probe directly up to 600 RNA targets in either fresh/fixed frozen or FFPE samples without the need for cDNA synthesis, and generates barcoded in situ sequencing libraries with higher efficiency compared to a previous cDNA-based library preparation approach, initially published in 2013, Cartana said. Furthermore, the new ISS kit sequences the barcodes in the libraries directly in situ, with enhanced signal-to-noise ratio and specificity compared to the previous state-of-the-art ISS technology. The new kit contains six sequencing cycles and decodes up to 600 barcodes using a standard fluorescent microscope.

Microbiologics SARS-CoV-2 RNA Process Control

Microbiologics has launched two new research-use-only products for COVID-19 research and quality control: a protein-coated RNA process control and an IVD control with pooled gene targets.

The new SARS-CoV-2 control features diagnostically relevant RNA sequences protected by phage protein, providing nuclease resistance even in nuclease-rich environments such as nasal secretions or plasma. This coating protects the RNA during the extraction process, preventing the false negatives that can occur with the use of naked RNA. The protein coating functions like the virus's protective envelope that sequesters and protects its RNA genome. Featuring genomic targets for all seven WHO COVID-19 testing protocols, this process control can be used for SARS-CoV-2 assay development, positive extraction, and spike-in controls.

The new SARS-CoV-2 Helix Elite control features a pool of large RNA molecules that match the viral sequences for the RdRp gene, S gene, E gene, and N gene. These pooled genetic targets offer broad compatibility with CDC- and WHO-specified test components to generate positive PCR signals.

ProteoGenix Human Immune COVID-19 Library

ProteoGenix has launched a Human Immune COVID-19 Library to facilitate the discovery of antibodies against SARS-CoV-2. Created using blood samples from dozens of recovered COVID-19 patients, the library is adapted for screening with phage display and features 1.2 x 1010 different clones. The phage display screening technology coupled with the library's diversity is expected to speed the discovery of antibodies with the strongest affinity, specificity, and viral blocking activity, the company said. ProteoGenix said that it also offers a broad diversity of ready-made SARS-CoV-2 antigens, as well as custom antigen development services. Within eight weeks, clients can receive three to 10 unique and royalty-free antibody sequences with optimal affinity.

Horizon Discovery FFPE, Liquid Biopsy OncoSpan Reference Standards

Horizon Discovery has added two new sample formats to its cell-based OncoSpan reference standards for use in the development and validation of workflows for cancer diagnostic assays. The company's OncoSpan range now includes formalin-fixed, paraffin-embedded and cell-free DNA formats for mimicking solid tumors and liquid biopsy samples, respectively, in addition to its genomic DNA format. Its cfDNA format offers more than 380 variants and 152 genes to help standardize liquid biopsy testing.

These cell line-derived reference standards closely mimic patient samples and offer an unlimited and reproducible resource to help ensure consistency during the establishment and validation of diagnostic assays, Horizon said. All three formats are delivered with batch-specific, next-generation sequencing data, orthogonally validated by droplet digital PCR, to allow researchers to further validate their analysis pipeline.

Meridian Bioscience Inhibitor Tolerant 1-Step RT-qPCR Mix

Meridian Bioscience launched its Inhibitor Tolerant 1-step RT-qPCR Mix, an enzyme master mix that eliminates the need for an RNA extraction kit before running a sample through a molecular assay. Meridian developed the master mix formulation because it said RNA isolation and purification is time consuming and expensive. The company also noted that RNA extraction kits have been in short supply during the COVID-19 pandemic. 

When combined with SARS-CoV-2 primers and probes, the proprietary master mix can be used by laboratories to eliminate RNA purification, reducing processing times by as much as 30 minutes and lowering test costs.

Sengenics ImmuKyne Protein Array

Sengenics has launched the ImmuKyne protein array. The array is based on the company's KREX technology for discovering autoantibody biomarker signatures for predicting drug response and severe immune-related adverse events. The new product enables simultaneous screening of more than 300 immunomodulatory autoantigens comprising clinically significant protein classes that may be implicated in acute respiratory distress syndrome (ARDS), such as cytokines, chemokines, and interleukins. All proteins on ImmuKyne are full-length, correctly folded, and functional with both conformational and non-conformational epitopes preserved, which is critical as 90 percent of antibody binding sites are conformational in nature, the company said. The new tool is designed to further COVID-19 research by helping users understand whether autoantibodies play a role in progression to severe disease in COVID-19 patients.

Caris Life Sciences MI Exome

Caris Life Sciences has launched MI Exome, a whole-exome next-generation sequencing-based assay.

The test covers 22,000 genes and detects point mutations, indels, copy number alterations, and about 250,000 exonic, intronic, and intergenic SNPs. MI Exome also includes analysis of tumor mutational burden, microsatellite instability, loss of heterozygosity, and homologous recombination deficiency, and can be used to interrogate bacteria, viruses and fungi, including cancer-related pathogens, to support microbiome analysis. Average turnaround time is less than 14 days. When paired with the Caris Molecular Intelligence profiling services, the test can help detect and characterize cancer to guide individualized treatment decisions, the company said.
