What is an Assay?Filters
Flow cytometry is employed to quantitatively measure cell surface and/or intracellular markers, enabling characterization of cell populations based on fluorescence intensity and light scatter properties. This assay utilizes a flow cytometer to analyze individual cells in suspension, providing multi-parametric data on cell phenotype, viability, activation state, or other biological attributes as defined by the experimental panel. Samples are processed, stained with fluorescently labeled antibodies ...

This assay captures administrative and clinical metadata associated with patient study visits, serving as a structured data collection framework rather than a biological measurement assay. It records visit-level contextual information such as visit dates, timepoints, subject identifiers, clinical site details, and protocol-relevant annotations that are essential for linking experimental samples and assay results to their proper clinical context. This metadata layer ensures traceability and data ...

DNA sequencing libraries are constructed from genomic DNA extracted from tissue samples through a series of enzymatic and physical processing steps, including DNA fragmentation, end-repair, adapter ligation, and amplification. This workflow prepares nucleic acid material for downstream high-throughput sequencing by converting extracted DNA into indexed, platform-compatible libraries. The resulting libraries enable comprehensive genomic or transcriptomic interrogation of tissue-derived specimens, ...

Flow cytometry is a laser-based, high-throughput single-cell analysis technique used to simultaneously measure multiple physical and fluorescent characteristics of cells or particles in suspension. This assay quantifies cell populations based on parameters such as cell size (forward scatter), granularity (side scatter), and fluorescence intensity of labeled surface or intracellular markers, enabling immunophenotyping, cell cycle analysis, viability assessment, and functional studies. Samples are ...
