What is an Assay?Filters
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 ...

This assay quantifies gene expression at single-cell resolution by linking individual cell transcriptomic profiles to associated experimental or clinical data, enabling integrative analysis across multiple data modalities. Single-cell RNA sequencing (scRNA-seq) technology is employed to capture and measure the transcriptional activity of individual cells, generating high-dimensional expression matrices that are subsequently processed through quality control, normalization, and dimensionality ...

Short read sequencing is a high-throughput next-generation sequencing (NGS) approach used to determine the nucleotide sequence of DNA or RNA fragments, enabling detection of genetic variants, gene expression profiles, or genomic features depending on the library preparation strategy employed. This assay involves fragmentation of input nucleic acids, adapter ligation, and amplification prior to sequencing on short-read platforms (such as Illumina), generating millions of short sequence reads ...

This assay captures metadata associated with tissue collection procedures, documenting critical provenance and contextual information for biological specimens obtained from study subjects. It records standardized parameters such as tissue type, anatomical source, collection method, preservation conditions, and relevant donor or sample identifiers to ensure traceability and reproducibility across downstream experimental workflows. This metadata serves as a foundational record linking collected ...

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, ...
