Biochemical assays are laboratory techniques used to study the chemical processes and interactions within living organisms. These assays often involve measuring the presence or activity of specific biological molecules, such as proteins, enzymes, or metabolites, in a sample. Some common types of biochemical assays include enzyme activity assays, protein quantification assays, and metabolite detection assays. These assays are critical for studying various biological processes, such as metabolism, signaling pathways, and gene expression, and are used in a wide range of research areas, including drug discovery, diagnostics, and biomarker identification. Biochemical assays can provide valuable information about the function of biomolecules and their role in disease development, making them essential tools in modern biological research.
