Streck is pleased to announce an expanded partnership with Ceres Nanosciences (Ceres) to distribute the Nanotrap® Extraction Advanced Technology (NEAT) Liquid Biopsy Kit – Streck BCT worldwide. The NEAT Liquid Biopsy Kit – Streck BCT is formulated to capture, concentrate and extract cfDNA from plasma samples isolated from Streck blood collection tubes. "Streck is excited to launch another innovative product from our strategic partner Ceres," said Matthew Kreifels, vice president of Sales, MarCom, and Business Development at Streck. "The NEAT Liquid Biopsy Kit creates efficiencies and results our customers will find invaluable when used in combination with Streck stabilization solutions." With liquid biopsy, cancer researchers have the power to identify critical biomarkers from a few milliliters of blood. However, these biomarkers can be in very small amounts, and when blood samples begin to degrade and release proteins and nucleic acids that can obscure the concentrations of biomarkers of interest, isolation becomes even more difficult. Combined use of Streck Cell-Free DNA BCT® and Nucleic Acid BCT™ with the NEAT Liquid Biopsy Kit ensures that samples remain the same from collection to analysis and that the cfDNA isolated from these samples for downstream analysis is high yield and high purity. "Ceres looks forward to seeing Streck's innovative customers use the NEAT Liquid Biopsy Kit and Streck blood collection tubes to push the frontiers of liquid biopsies," said Robbie Barbero, Ph.D., chief business officer at Ceres Nanosciences. Performance characteristics of Cell-Free DNA BCT have only been established on the Guardant360® CDx assay. Nucleic Acid BCT and NEAT Liquid Biopsy Kit – Streck BCT are for Research Use Only. Not for use in diagnostic procedures. Nucleic Acid BCT should only be used for research or in the development of new assays.
The Nanotrap® Protein Enrichment Affinity Discovery Kit (Nanotrap® Discovery Kit) delivers highly reproducible, deep proteome coverage while reducing per-sample cost compared to other enrichment kits. The manual Nanotrap Discovery Kit enhances proteome coverage and depth while improving workflow reproducibility and cost efficiency.

Nanotrap® Microbiome Particles are magnetic hydrogel particles designed to capture and concentrate low-abundance microbes (including bacteria, viruses, and fungi) from complex environmental, wastewater, and clinical samples, improving detection sensitivity across downstream workflows. Many labs struggle to detect microbial targets in complex samples such as wastewater, blood, and urine. Low target abundance combined with PCR inhibitors often results in weak signal or false negatives when using standard extraction workflows. Nanotrap® Microbiome Particles address these limitations by physically capturing and concentrating intact microbes prior to extraction, improving recovery and enabling more reliable detection across downstream workflows. Key Advantages: -- Reduce false negatives: Concentration of low-abundance microbes increases detectable signal -- Remove inhibitors: Separation from complex matrices improves PCR and sequencing performance -- Enable detection at low levels: Improves recovery in samples near or below assay limits -- Process larger sample volumes: Efficiently concentrate microbes from mL-scale inputs -- Simplify workflows: Magnetic separation eliminates the need for centrifugation or filtration Extensive Sample Type Compatibility Environmental & Wastewater Samples - Wastewater - Surface waters - Blackwater - Sludge - Airplane lavatory fluid - Food wash Clinical & Biological Samples - Urine - Whole Blood - Sputum - VTM/UTM - Saliva - plasma Capture and concentrate low abundance microbes Nanotrap® particles utilize affinity-based capture to bind and concentrate low-abundance microbes from complex samples, without relying on antibodies, enabling improved reagent stability and consistent performance. Seamless integration with downstream workflows Compatible with qPCR, dPCR, ddPCR, sequencing, immunoassays, and culture-based methods without requiring changes to existing workflows. Consistent performance in complex matrices Demonstrated performance across diverse and inhibitor-rich environmental and clinical sample types. Eliminate centrifugation and filtration steps Streamlines sample preparation by removing the need for centrifugation, filtration, or precipitation-based concentration methods, enabling more consistent recovery.

SKU 34XXX This study evaluated the performance of Nanotrap® Protein Enrichment Affinity Kits (PEAK) for mass spectrometry-based proteomic analysis of ascites fluid from patients with high-grade serous ovarian cancer (HGSOC). Because ascites contains abundant plasma proteins that mask low-abundance biomarkers, the authors investigated whether Nanotrap hydrogel particles could improve proteome coverage by selectively enriching low-abundance proteins while excluding high-abundance species. Key Findings Significantly improved proteome depth - Nanotrap enrichment identified more than 2–3× as many proteins as direct (neat) ascites analysis. - Across 10 clinical ascites samples, Nanotrap-enriched workflows identified 3,480–4,000 proteins, compared with 1,505 proteins in unenriched samples. Effective dynamic range compression - Albumin, which represented 74% of the neat ascites proteome, was reduced to approximately 1.5% following enrichment. - The remaining (lower-abundance) proteome was enriched 4.8–7.1-fold, substantially improving detection of potential biomarker candidates. Complementary particle chemistries - Three Nanotrap particle types (A, B, and C) exhibited distinct capture profiles due to differences in affinity chemistry and surface charge. - Multi-particle combinations generally identified more proteins than individual particle types, demonstrating complementary enrichment capabilities. Selective enrichment rather than simple depletion - On average, 61% of quantified proteins were enriched, while 39% were depleted, indicating that Nanotrap particles selectively reshape the detectable proteome through affinity capture and molecular sieving rather than acting solely as an abundant protein depletion method. Reproducible performance - Technical reproducibility remained strong across enrichment methods, with median coefficients of variation between 10–22%. - The AC and ABC particle combinations demonstrated the best balance of proteome coverage and reproducibility for biomarker discovery applications. Implications for Nanotrap Technology This study demonstrates that Nanotrap PEAK substantially enhances proteomic analysis of ascites fluid by: - Increasing protein identifications and proteome depth. - Removing interference from highly abundant plasma proteins. - Enabling detection of lower-abundance proteins that may serve as predictive or prognostic biomarkers. - Providing a scalable, magnetic, and automation-compatible sample preparation workflow suitable for mass spectrometry-based biomarker discovery. The authors conclude that Nanotrap PEAK is a cost-effective, scalable, and reproducible enrichment technology that significantly improves the analytical performance of LC-MS/MS for complex biofluids such as ascites. By compressing the dynamic range and expanding detectable proteome coverage, Nanotrap particles provide a powerful sample preparation approach for ovarian cancer biomarker discovery and other clinical proteomics applications.

Nanotrap® Particles are hydrogel particles, functionalized with chemical affinity baits that have very high affinities for different classes of analytes, such as proteins, peptides, nucleic acids, microbes, hormones, drugs-of-abuse, and extracellular vesicles. The unique hydrogel structure facilitates rapid exchange with the sample for rapid binding. Nanotrap particles are magnetically functionalized, allowing for easy recovery from the sample. This process can be automated, enabling high-throughput sample processing. The technology platform is well-validated, with over 80 publications and preprints and 14 patents to date. Hydrogel particles facilitate rapid binding and removal of interfering substances, enabling analyte capture, concentration, and purification. Hydrogel particles are highly versatile, with demonstrated functionality across sample types and volumes, ranging from small-volume plasma samples to large-volume wastewater samples. Well-characterized affinity baits capture and concentrate multiple analytes from a type and size of the sample, unlocking access to multiplex and multi-omic testing modalities. Magnetic and automation-ready, ideal for high-volume workflows or point-of-care devices Room temperature stable for 6 years, providing cost-effective durability in a wide range of global settings
