Discovery proteomics refers to the large-scale,untargeted identification and quantification of proteins in a biological sample. Unbiased proteomics is possible through the LC-MS/MS platform,which captures thousands of proteins simultaneously without prior selection. This stands in contrast to targeted assays that can only measure a predefined set of proteins. This includes Olink Reveal,a highly sensitive assay capable of measuring approximately 1000 predefined protein targets,suitable for large-scale studies with pre-defined panels.
Discovery proteomics is particularly valuable for early research phases,where the goal is to identify novel biomarkers,characterize disease mechanisms,or understand how a biological system responds to a treatment before narrowing your focus to specific candidates.
"},{"faq_question":"What sample types can be used for unbiased proteomics?","faq_answer":"CellCarta’s discovery proteomics workflows support a range of biological matrices,including blood,serum,plasma,tissue biopsies,and FFPE specimens. The appropriate sample type depends on the scientific question,the available sample volume,and the downstream objectives of the program. For low-volume samples,Olink Reveal can quantify approximately 1,000 protein targets from as little as 1 µL of blood. For broader,hypothesis-generating profiling across tissue or biopsy specimens,LC-MS/MS-based discovery proteomics provides comprehensive coverage. CellCarta’s scientific team can advise on the most appropriate approach based on your specific sample constraints and study design.
"},{"faq_question":"How does bioinformatics fit into the discovery proteomics workflow?","faq_answer":"Bioinformatics is integrated into CellCarta’s discovery proteomics workflow from the point of data acquisition,not added as a separate downstream step. A dedicated bioinformatics team applies standardized analytical pipelines designed for reproducibility,traceability,and regulatory readiness. This includes protein identification and quantification,normalization,statistical analysis,and pathway or network interpretation where relevant. The goal is to produce datasets that are not only scientifically meaningful but structured in a way that supports regulatory review and enables confident decision-making on biomarker candidates or mechanistic signatures.
"},{"faq_question":"Can discovery data connect to later-phase clinical work?","faq_answer":"Yes. One of the key advantages of conducting discovery proteomics with CellCarta is that we also offer downstream biomarker quantification,targeted assay development,and bioanalytical testing. This means discovery findings can be transitioned directly into verification or clinical assay workflows without the delays and data transfer risks associated with changing laboratory partners. CellCarta’s multi-omic capability,spanning proteomics,immunology,histopathology,and genomics under one roof,further supports programs that need to interpret protein data in the context of other biological modalities. This integrated path from discovery to clinical testing is a practical advantage for programs working toward regulatory submission.
