Advancing the future of diagnostics

Many challenges exist in lateral flow assay (LFA) manufacturing, from low-volume liquid deposition to device assembly and packaging. In the development and batch-level manufacturing stage, antibody and conjugate selection, material selection, and reagent delivery are critical. In addition, batch-level manufacturing is typically segmented and requires manual quality control (QC) and material assembly. When transitioning from low-volume manufacturing to mass-production, there are a different set of challenges presented, particularly in maximizing throughput without sacrificing quality. In addition, material handling and assembly, automated QC, and drying are critical in the large volume production. Critical to successful lateral flow production is the transition from the batch to mass-production phases.

In this webinar, you will:

• Learn unique challenges and solutions to reagent deposition
• Learn the process and techniques used in batch-level LFA manufacturing
• Learn the unique challenges presented in large-scale LFA manufacturing as well as solutions to achieve a high-quality product while balancing throughput and efficiency
• Learn strategies for scale-up from batch manufacturing to mass-production

Cell-free DNA (cfDNA) is currently trending as a biomarker from liquid biopsy in several clinical applications, including oncology, organ and transplant medicine, and non-invasive prenatal testing (NIPT). Although considerably less invasive than tissue biopsy, due to the small amount of cfDNA found in circulation, there is a need to use efficient, highly sensitive extraction protocols coupled with robust and reliable technologies, such as next-generation sequencing (NGS) to detect these mutations.

Join our webinar hosted by Monika Seidel (PhD) to discuss the results of a study using Cytiva’s magnetic silica bead-based Sera-Xtracta™ Cell-Free DNA extraction kit* and targeted NGS for cancer biomarker detection in advanced non-small cell lung cancer (NSCLC) patient samples. The study demonstrates performance in a clinically relevant scenario where patient samples are analyzed for therapy stratification

Dried blood spot (DBS) have been used as an alternative to plasma to increase access to HIV viral load monitoring and early infant diagnosis. DBS has also been applied as a sample collection method to detect SARS-CoV-2 downstream. Recently, the FDA approved the Vibrant COVID-19 antibody chemiluminescence immunoassay. The intended use is for the qualitative detection and differentiation of IgM and IgG antibodies to SARS-CoV-2 in human serum on Whatman™ 903 Proteinsaver Card (a sample collection card) using finger stick blood specimen.

Immunoassay developers are constantly striving to create tests that address unmet diagnostic needs. A critical prerequisite for good assay performance is the design, production, and characterization of reagents that are highly sensitive and selective. This includes selecting the analyte of interest to measure, the sample matrices in which measurements will be made, as well as determining the critical success factors for the assay, for example, sensitivity, throughput, and dynamic range.

Biacore™ surface plasmon resonance (SPR) has become an important optical biosensing technology due to its real-time, label-free, and automated analysis.

Omics—the study of the genome, proteome and transcriptome—is gaining in importance in relation to cancer diagnostics. After collection, tissue samples need to be processed and single cells isolated as quickly as possible to make sure cell viability remains high and minimize any changes in the cellular transcriptome. Current tissue disaggregation techniques are manual and time-consuming and often result in sample loss via ruptured or attached cells that are unsuitable for library preparation. Mild, yet automated tissue processing is needed to ensure that cell yield and integrity consistently remains high. The result must be a viable cell suspension, representative of the original sample, for use in high-throughput single-cell research. Join Priya Hari to discuss how effective tissue processing can help single-cell omics to advance.

Learning objectives:

• Highlight challenges with current tissue processing techniques
• Discuss the advantages of mild, automated tissue dissociation for optimizing cell viability
• Review data demonstrating the advantages of automated processing for high-throughput single-cell omics applications
