Enzyme-Linked Immunosorbent Assay (ELISA) is a highly sensitive and specific analytical technique used to detect and quantify proteins, hormones, antibodies, and other biomolecules in various samples. This method utilizes antigen-antibody interactions, where an enzyme-linked antigen or antibody generates a measurable color change, indicating the presence and concentration of the target analyte. ELISA is widely employed in applications such as allergen testing, biomarker analysis, and quality control in pharmaceuticals and food products, providing accurate and reliable results across a range of industries.
Absorbance-Based Spectrophotometry is a widely used analytical technique for quantifying the concentration of substances in a sample by measuring the amount of light absorbed at specific wavelengths. This method relies on the principle that different compounds absorb light at characteristic wavelengths, allowing for precise identification and quantification. It is commonly used in applications such as chemical analysis, quality control, and the study of biochemical reactions, providing accurate and reliable data for a wide range of samples in various industries.
