96 Well ELISA
The 96-Well ELISA format is a standard configuration for performing enzyme-linked immunosorbent assays, supporting high-throughput analysis across a range of biological and clinical research applications. It allows simultaneous processing of multiple samples or replicates, optimizing workflow efficiency in quantitative detection of specific proteins, antigens, antibodies, or other biomolecules.
Content of a 96-Well ELISA Plate
- Pre-Coated Microplate: The 96-well microplate is pre-coated with specific antibodies or antigens designed to bind the target molecule in each sample, offering high binding capacity and consistency.
- Sample and Control Wells: The plate layout includes designated wells for standards, controls, and unknown samples, ensuring rigorous quantitative and qualitative assessments.
- Detection Reagents: These are enzyme-linked secondary antibodies (typically conjugated with HRP or AP), which bind to the captured target molecule and enable signal generation.
- Substrate Solution: The substrate solution, such as TMB for HRP-based ELISAs, reacts with the enzyme to produce a colorimetric signal proportional to the amount of target analyte in the well.
- Wash Buffers and Stop Solution: Wash buffers are used to remove unbound reagents, while the stop solution halts the enzymatic reaction at the optimal point, stabilizing the signal for measurement.
Applications of 96-Well ELISA Plates
96-Well ELISA plates are widely used in:
- Biomarker Quantification: Used in disease research, these plates help in quantifying biomarkers indicative of disease states.
- Drug Development: Employed to monitor pharmacokinetics and immunogenicity in preclinical and clinical studies.
- Vaccine Development: Critical in measuring immune response levels, such as antibody titers or cytokine release.
- Diagnostics: Utilized in clinical diagnostics to detect pathogens, autoantibodies, or disease-specific proteins.
Benefits
The 96-well ELISA format is valued for its high sensitivity, reproducibility, and scalability. Its structured layout facilitates parallel processing, enabling consistent measurements across large sample batches with precise quantitative results essential for reliable data analysis in clinical and research settings.
