Fluidigm and Olink Bioscience Bring a New Level of Protein Biomarker Discovery to the Life Science Research Market

Fluidigm and Olink Bioscience have teamed up to enable interrogation of 96 samples across 92 proteins in a single run from one microliter of sample in less than a day.

The two companies will co-market the combination of their respective products — Fluidigm’s BioMarkTM HD System and Olink Bioscience’s Proseek® Multiplex technology — bringing protein research to the Fluidigm platform and Olink Bioscience’s protein detection assays to the high-throughput, high reproducibility and unparalleled sensitivity realm of Fluidigm’s real-time PCR system.

Fluidigm’s BioMark HD System and Olink Bioscience’s Proseek Multiplex technologies provide researchers with the highest throughput multiplexing solution for protein biomarker discovery in the market today. Typically, researchers are limited to working with a few tens-of-protein biomarkers at a time. Using the BioMark HD System with the Proseek Multiplex Oncology I 96×96 Kit, a researcher can simultaneously analyze 96 human samples against a panel of 92 analytes, such as growth factors, inflammatory markers, soluble receptors, or cancer antigens. With the addition of four control analytes (two incubation controls, and extension and detection controls), researchers can now obtain results for up to 9,216 reactions in just a few hours.

The first 92-plex Olink panel, available now, is focused on biomarker discovery for cancer. Panels addressing cardiovascular disease and inflammation are expected to be offered later this year.

“Protein research is so important because these biomarkers are used to monitor health states and predict treatment outcomes in patients. One of the biggest trends in the life sciences industry today is research to uncover biomarkers that can lead to companion diagnostics,” said Simon Fredriksson, Olink Bioscience president and chief executive officer. “Conventional immunoassays have been unable to scale due to increasing antibody cross-reactivity when more and more assays are run simultaneously. Olink’s Proseek Multiplex generates high quality data even in highly multiplexed formats, and using these assays in conjunction with Fluidigm’s BioMark HD System gives protein researchers easy access to unprecedented volume and quality of data.”

The Olink Bioscience assay provides a signal when pairs of antibodies equipped with DNA reporter molecules bind to their targets to create new DNA amplicons. The amplicons are subsequently quantified by high throughput real-time PCR. With PCR’s large dynamic range and superb sensitivity, in combination with Olink Bioscience’s unique protein detection assays, the opportunities are enormous for powerful analysis of multivariate biomarker patterns.

“Analyzing 92 proteins from one microliter of sample enables new biomarker discovery and validation,” said Gajus Worthington, Fluidigm president and chief executive officer. “Many sample sources, including those from biorepositories or model organisms, are limited, and researchers can simply run out before they are able to find useful biomarker panels. The combination of Fluidigm’s BioMark HD System and Olink’s Proseek Multiplex assay represents a robust new tool for the protein research community.”

Fluidigm’s BioMark HD System is a multi-application genomics and proteomics platform that provides results equivalent to the gold standards for every respective experimental approach. The system produces high-quality data from RNA, miRNA and DNA from sample sizes down to the single cell level — and now extends to proteins. The BioMark HD System performs analysis of protein expression, gene expression, copy number variation, SNP genotyping, and digital PCR.

Olink Bioscience’s Proseek Multiplex is a multivariate protein biomarker detection kit based on Olink’s proprietary Proximity Extension Assay (PEA). It uniquely allows multiplexing of immunoassays without compromising assay performance. PEA uses pairs of oligonucleotide-labeled antibodies equipped with DNA reporter molecules to bind to proteins of interest in a highly specific manner, solving the antibody cross-reactivity dilemma that plagues and limits conventional protein assays.

PerkinElmer Expands Prenatal Screening Test Offerings, Introducing First Early Onset Preeclampsia Screening Test in the U.S.

PerkinElmer, a global leader in human and environmental health and an innovator in the field of prenatal screening for more than thirty years, announced today the first available early onset preeclampsia screening test in the United States. The PreeclampsiaScreen™ | T1 serum screening test enables physicians to more precisely detect asymptomatic patients in the first trimester of pregnancy who are at high risk for developing the dangerous condition, allowing for earlier identification, management and intervention. Early onset preeclampsia is a potentially serious condition that affects 0.5% of all pregnancies, often contributing more to the pregnant mother’s and baby’s risks of morbidity and mortality than does the late form of the disorder.

“This first of its kind screen is our latest commitment to providing clinicians with new, innovative ways to address some of today’s most challenging prenatal clinical scenarios,” said Jim Corbett, Senior Vice President and President, Diagnostics and Life Sciences & Technology for PerkinElmer. “Together with our recent advances, including offering a non-invasive prenatal test based on cell-free fetal DNA, plus a wide range of prenatal testing from biochemical screening to SNP microarray testing to detect birth defects and chromosome abnormalities, we’re giving physicians effective new tools for patient management.”

According to Dr. Jiri Sonek, MD RDMS, President, Fetal Medicine Foundation USA, and Adjunct Professor, Department of Obstetrics and Gynecology from Wright State University, “Preeclampsia is one of the remaining great challenges in obstetrics. It is a major cause of maternal, fetal, and neonatal morbidity and mortality. Fortunately, some physicians may recommend a simple and inexpensive intervention to reduce the risk of preeclampsia which is available in the form of low-dose aspirin. However, this treatment is effective only if begun early in pregnancy. That is why first trimester screening is such a critical component of preeclampsia prevention.”

Early onset preeclampsia is defined as preeclampsia, a sudden increase in blood pressure and protein in the urine, which leads to delivery of the fetus prior to 34 weeks’ gestation. If found early, options such as increased monitoring, modified activity, bed rest and medication can help reduce or avoid complications related to early onset preeclampsia.

PreeclampsiaScreen™ | T1 is administered during the first trimester of pregnancy through a simple blood test to detect three biochemical markers in the mother’s blood: PAPP-A (pregnancy-associated plasma protein-A); PlGF (placental growth factor) and AFP (alpha fetoprotein) that, when evaluated collectively with personal demographic data, provide an individual risk of developing early onset preeclampsia. Physicians have the option to provide two additional biophysical measurements for their patients — mean arterial pressure (MAP) and uterine artery Doppler pulsatility index (UtAD-PI) – each increasing the sensitivity of the screen when included in the testing protocol.

OGT Releases New CytoSure™ Microarray for Cancer Research

Oxford Gene Technology (OGT), provider of innovative genetics research and biomarker solutions to advance molecular medicine, has released a new microarray to improve the accuracy and efficiency of cancer research. The CytoSure™ Cancer +SNP array (4x180k) combines long oligo array comparative genomic hybridisation (aCGH) probes with fully validated single nucleotide polymorphism (SNP) content, providing the superior detection of both copy number variations (CNVs) and loss of heterozygosity (LOH) on a single chip. The array has been optimised in collaboration with Professor Jacqueline Schoumans from the Lausanne University Hospital in Switzerland, an expert in both aCGH and cancer genomics. Unique to the proprietary CytoSure™ Cancer +SNP array, any reference sample can be used for analysis without changes to the standard aCGH protocol and, thanks to novel SNP probe chemistry, no restriction digest is required. The capacity to use matched samples is a particular advantage for research into genetic aberrations in cancer, enabling any constitutional abnormalities to be filtered out.

Professor Schoumans commented: “The development of a new microarray with the capacity to detect both CNVs and LOH simultaneously was vital for improving the efficiency and quality of our research. By working very closely with the technical experts at OGT, we have constructed a new array that allows users to simultaneously screen a wide genomic background for CNVs and LOH, while also enabling in-depth CNV analysis on 1500 known cancer-associated genes. This approach produces accurate and insightful data, with all aberrations clearly highlighted and filtered using OGT’s excellent CytoSure Interpret Software.”

The 60-mer oligonucleotide probes utilised in the array provide a high signal-to-noise ratio and highly sensitive detection; this makes them ideal for research into complex malignant tissues. Thanks to OGT’s CytoSure Interpret Software, data analysis is rapid, reliable and simple to carry out, including updated features, such as the B-allele frequency plot, that have been optimised for the identification of biologically relevant genomic variants in tumour samples.

James Clough, Executive Vice President Commercial at OGT, said: “The new CytoSure™ Cancer +SNP array forms part of OGT’s ongoing strategy to design specialised microarrays to help increase our understanding of cancer formation and development. We plan to further add to this portfolio in the coming months, with the introduction of our Cancer Cytogenomics Microarray Consortium (CCMC) array design. By offering both genome-wide CNV and SNP detection, these arrays will prove a valuable tool for efficiently and accurately defining the genetic nature of a given tumour, facilitating research into more efficacious, targeted treatments.”
