Cell phenotyping is the process of characterizing cell populations by idebntifying their surface and intracellular markers in solid tissue and liquid biopsy samples. Flow cytometry is the most common and versatile technology for cell phenotyping,but alternative platforms,including multiplex immunofluorescence,can be utilized depending on the sample type. In drug development and clinical research,cell phenotyping allows scientists to monitor how specific immune cell subpopulations,such as T-cells,B-cells,NK cells,Tregs,and MDSCs,change in response to a therapeutic agent.
\nAt CellCarta,cell phenotyping is performed predominantly with flow cytometry and supported by expert assay design,complete data reports,and quality control in accordance with GCP,GLP,and GCLP standards.
"},{"faq_question":"What flow panels do you support for cell phenotyping?","faq_answer":"We support a wide range of flow panels for cell phenotyping,including off-the-shelf (OTS) panels validated at all global sites and custom panels designed to your specific study goals. Supported panel applications include T-cell activation and exhaustion,B-cell phenotyping,TBNK identification (with IVD status options for regulatory submissions),intracellular cytokine staining (ICS),phosphoflow,basophil activation test (BAT),and HLA-restricted multimers.
\nFor highplex assays,our scientists can apply Boolean analysis on main cell subsets for unsupervised clustering and dimensionality reduction algorithms. This added feature enables rapid data analysis for studies that require a quick turnaround time.
"},{"faq_question":"How does CellCarta ensure data quality and regulatory compliance?","faq_answer":"Quality control is applied at every step in accordance with the relevant regulatory requirements (GCP,GLP,and GCLP) and our sites are CAP-accredited and/or CLIA-certified. Panels are validated to the same standard across all global sites to support multicenter trials. Our scientists deliver complete data reports,and cross-site standardization on platforms to ensure consistent,reproducible flow cytometry readouts regardless of which site processes your samples.
"},{"faq_question":"What sample types are accepted for cell phenotyping assays?","faq_answer":"Our cell phenotyping services accept a wide range of sample types,including whole blood and cryopreserved or fresh peripheral blood mononuclear cells (PBMCs). Our team will advise on the appropriate collection and sample management approach for your specific study design.
"},{"faq_question":"What cell populations can be identified?","faq_answer":"Our cell phenotyping services can identify all major cell lineages including TBNK (T cells,B cells,NK cells),regulatory T cells,and myeloid-derived suppressor cells (MDSCs),as well as rare cell subsets such as basophils,stem cells,and antigen-specific cells. Our multiparametric panel design enables you to assess multiple populations and markers within a single assay,optimizing your sample use while providing a comprehensive picture of immune composition.

\nWe harness the power of multiparametric flow cytometry to investigate several markers at once,producing the data needed to help move your project forward.
\nCellCarta can implement and validate off-the-shelf or custom assays for cell phenotyping that are adapted to your study’s needs,ensuring comprehensive data that’s best suited for your program’s markers and populations of interest. Panel applications can include:
\nExpert-level analysis can be conducted by our bioinformatics team using our cloud-based CellEngine®software.
\nWith autogating tools,plug-in support,and fast algorithms,our software can deliver high-quality data to clients in record time.
\nCellEngine is available as part of our bioanalytical services,or as a software-as-a-service (SaaS),allowing researchers to perform independent data analysis and visualization.
\nOur multiparametric flow cytometry platforms can identify all major cell lineages (TBNK,Treg,MDSC,etc.) alongside rare cell subsets (basophils,stem cells,antigen-specific cells,etc.). This provides in-depth characterization of all relevant cell subpopulations with exceptional sensitivity.
