ELISA,or enzyme-linked immunosorbent assay,is a solid-phase immunoassay that uses enzyme-linked antibodies to detect an analyte of interest. Antibodies directed against the target protein bind to the target ligand,and the enzyme-linked detection system generates a measurable signal that can be quantified. ELISAs are a well-established,widely accepted method for biomarker measurement.
"},{"faq_question":"When is ELISA the right assay for my program?","faq_answer":"ELISA services are well-suited for programs requiring focused measurement of a limited set of biomarkers. They are commonly used when robust,reproducible single-analyte data is needed and are often combined with other cellular assays,including ELISpot and flow cytometry,when broader immune profiling is required.
\nCellCarta has proficiency in numerous immunoassays that are selected based on your program’s specifications. If your program requires multiplexing or multi-analyte detection,platforms such as Olink™,Ella™,and MSD® may be implemented instead. Consult with our team to discover the right workflow for your study.
"},{"faq_question":"What compliance levels are available for CellCarta ELISA services?","faq_answer":"CellCarta’s ELISA services are available at and can be validated to all regulatory requirements. The appropriate compliance tier is determined by the stage and requirements of your program. CellCarta’s scientific team will work with you to define the right approach for your specific assay and program goals.
