Enabling the Illumina DNA PCR-Free Library Prep Kit on the Miro Canvas NGS Prep System

White Paper

There is an increasing demand for next-generation sequencing (NGS) library preparation protocols that do not include PCR to avoid the introduction of PCR bias into the pool of DNA for sequencing. The Illumina DNA PCR-Free Prep kit follows a PCR-free workflow and is being increasingly used in sensitive applications such as whole-genome sequencing (WGS) because it is both flexible and easy to automate. Its on-bead tagmentation step is especially important for reducing library preparation time and sample input requirements. These features are of great interest for clinical applications such as tumor evaluations and newborn diagnostics and are also important for research uses.

Miro Canvas is a digital microfluidics (DMF) platform that allows custom low-throughput workflow automation for complex protocols such as NGS library preparation. The system is compatible with a wide range of reagents. This application note describes the results that can be expected when using the Illumina DNA PCR-Free Prep kit in a protocol developed for Miro Canvas. The resulting research-use-only libraries can then be sequenced using Illumina platforms.

A Report on the Non-Invasive Prenatal Testing Proficiency Exercise of a Trisomy 21 Female cfDNA Sample

White Paper

Proficiency testing allows a laboratory to evaluate if its test performance is satisfactory for the intended clinical purpose. It enables inter-laboratory comparisons by providing the same material to participants. This is important for non-invasive prenatal tests (NIPS or NIPT) since they are not FDA-approved diagnostic tests and are only intended for screening.

This white paper from LGC SeraCare describes a study examining the 2022 College of American Pathologists NIPT participant summary report regarding a case that showed a disparity in fetal sex chromosome status between the participants, with findings supporting the importance of appropriate diagnostic follow-up, genetic counseling, and clinical correlation in prenatal testing.

Multi-Site Evaluation of Novel BRCA1/2 Reference Materials Including Large Genomic Rearrangements

White Paper

The BRCA1 and BRCA2 tumor suppressor genes limit DNA damage. Consequently, loss-of-function mutations in these genes lead to increased incidence of breast, ovarian, and prostate cancer. Accurate detection of BRCA variants is paramount for patients with somatic cancer to guide treatment strategies, such as eligibility for PARP inhibitor therapy, and for individuals carrying inherited mutations to consider preventive actions. However, 27 percent and five percent of pathogenic mutations in BRCA1 and BRCA2, respectively, are large genomic rearrangements (LGRs) that are particularly difficult to detect in PCR and targeted NGS-based assays. Therefore, the development of assays that consistently detect BRCA1/2 LGRs will require reliable reference materials for validation, troubleshooting, and routine quality control.

This scientific poster from LGC Seracare describes the development and multi-platform validation of a set of novel multiplexed reference materials containing 20 clinically relevant BRCA1/2 variants, including 11 large genomic rearrangements.

Multi-Site Evaluation of FFPE Homologous Recombination Deficiency Reference Materials

White Paper

Homologous recombination deficiency (HRD) arises when defects in DNA repair pathways occur, leading to genomic instability. HRD status is an emerging therapeutic biomarker; NGS assays that measure it can be used to stratify ovarian and breast cancer patients and determine eligibility for clinical trials, PARP inhibitors, and platinum-based therapies. Seraseq FFPE HRD reference materials were developed to cover a range of genomic instability scores to help NGS HRD assay validation and development.

This scientific poster from LGC SeraCare discusses a multi-site evaluation across various platforms of high-positive, low-positive, and negative HRD reference materials.

The Critical Role of NGS Reference Materials in Precision Oncology Applications

White Paper

Cancers can be caused by a multitude of distinct genetic abnormalities, and each tumor is unique. Dozens of new targeted therapies have been developed in recent years, but the challenge of providing optimal care to cancer patients lies in the ability to match the genetic profile of the tumor to the most appropriate therapy. Advances in next-generation sequencing (NGS) technologies have enhanced the identification of hundreds of mutations that may contribute to disease progression, and the development of new diagnostic NGS assays is continually evolving. These assays can profile genetic mutations to enable precision diagnostics, personalized treatment selection, stratification of patients for clinical trials, and improved disease monitoring.

This white paper from LGC SeraCare describes the role reference materials play in developing and validating robust precision oncology assays that can perform with the accuracy, sensitivity, and reproducibility required for clinical use, as well as considerations for selecting the most appropriate provider of reference materials.
