Responding to a Pandemic

White Paper

ABC Labs, based at the Karolinska Institute campus in Stockholm, Sweden, was founded soon after the start of the pandemic to establish large-scale PCR and ELISA COVID-19 testing. The laboratory analyzes thousands of tests daily in partnership with Sweden’s Public Health Agency and regional and private healthcare providers.

This case study brief from Tecan describes how ABC Labs employed robotic workstations to scale up their PCR and serology testing over the course of the pandemic from hundreds of samples a day to nearly 20,000.

Protecting Data Integrity and Quality Assurance in Times of Crisis: Technologies Essential to SARS-CoV-2 Sequencing


Clinical Reference Laboratory (CRL) is one of the largest privately held clinical testing laboratories in the US. As the COVID pandemic arose last year, the lab sought to develop a patient-friendly sample collection experience based on saliva instead of nasal pharyngeal swabs. But the test needed to be just as accurate and reliable as standard SARS-CoV-2 tests.

In this on-demand eCase study, Heather Fehling and Rob Grbac of CRL review how they quickly developed a PCR-based COVID-19 saliva test and then rapidly scaled from 300 samples per day to 30,000 samples per day. They discuss how they optimized their processes with the help of Artel’s Multichannel Verification System and review lessons learned from the project.

White Paper

This transcript is a companion piece for a GenomeWeb eCase Study in which Heather Fehling and Rob Grbac of Clinical Reference Laboratory discussed how their lab quickly developed a PCR-based COVID-19 saliva test and optimized their processes with the help of Artel's MVS technology. The transcript of the presentation has been lightly edited for clarity and length.

Avoid False Positive ELISA Data

White Paper

Complex samples such as serum and plasma contain a wide variety of substances that may interfere with ELISA outcomes, resulting in false positive data.

This application note from Bio-Techne features three examples of how the company’s proprietary blocking reagents help prevent false positive data in its Quantikine ELISAs as well as that of competitors.

Learn about the importance of optimization in assay development and how Bio-Techne’s in-house testing and careful selection of antibodies, proteins, and diluents help ensure your ELISAs will perform with optimum precision, specificity, accuracy, and sensitivity.

4 Fundamentals of Immunoassay Quality

White Paper

Immunoassay kits can be convenient time-saving tools, but not all assays are created equal. This white paper from Bio-Techne provides a detailed review of the core elements that form the foundation of immunoassay quality and their role in helping to deliver robust, reproducible, and reliable results.

The white paper examines each of these component – recovery, linearity, specificity, and consistency – in detail. It also outlines the strict procedures and protocols Bio-Techne applies to make sure each assay delivers superior performance and consistency as part of a stringent quality control program.

Luminex Assay Users Guide

White Paper

While measuring multiple analytes in a single sample offers numerous advantages, achieving optimum immunoassay outcomes requires careful consideration of multiple factors.

LGC, Biosearch Technologies Accelerate Probe and Primer Production to Enable COVID-19 Testing with the SP Genevac HT Series 3i Evaporator

White Paper

During the COVID-19 pandemic, LGC, Biosearch Technologies, has been accelerating its production of oligonucleotides and other critical test kit components. However, there are problems that can slow production workflow. One particular bottleneck is in the drying process. The output from the synthesis labs and purification group can far outweigh the aliquoting, loading and drying workflow, which causes workflow to slow down upstream.

LGC, Biosearch Technologies, is using SP Genevac technology in order to facilitate the rapid production of probes and primers, and creating them to the high standards needed in this extremely challenging situation.

Freeze-Drying COVID-19 Diagnostics: Formulation & Process Development and Lyophilizer Selection

White Paper

Lyophilization may be considered a relatively gentle drying process, but there are still risks and pitfalls when applying it to biomolecular reagents in diagnostic tests. Reagents typically used in ELISA- and PCR-based diagnostic kits for diseases such as COVID-19 tend to contain labile components, such as enzymes that need preserving for longevity in the supply chain or antibodies to test for a patients response to the virus, which can be challenging to stabilize for commercial use.

This technical note discusses various aspects of formulation and cycle development in the lyophilization of diagnostic reagents, including those required for COVID-19 testing.

PCR Diagnostic Kits & Freeze-Drying Considerations

White Paper

Polymerase chain reaction (PCR) is a method widely used in molecular biology to make many copies of a specific DNA segment. There are numerous processing challenges with PCR, however. The various component solutions need to be accurately combined in a plate well or tube "cocktail." The components require refrigeration and they have a relatively short shelf life and cross contamination is a concern. R&D lab bench pipetting errors can also be troublesome.

Freeze-drying has become an integral part of the PCR process and is used for both individual reagents as well as end-product test kit reagents.

This technical note discusses the considerations for freeze-dried PCR reagents and diagnostic kits.
