Biochemical assays are laboratory techniques used to detect, measure or analyze biological molecules such as proteins, enzymes, DNA, RNA or metabolites. These assays involve a series of chemical reactions that produce a measurable signal, which is then used to determine the concentration, activity, or identity of the molecule of interest. Performing accurate and reliable biochemical assays requires specialized knowledge and skills in various techniques such as spectrophotometry, chromatography and electrophoresis.

Flow cytometry is a specialized laboratory technique that measures the physical and chemical characteristics of individual cells or particles in a fluid sample. It is used to analyze and sort cells based on their size, shape, structural and functional features, and other properties. Flow cytometry is widely utilized in medical, biotechnological, and pharmaceutical research, as well as in clinical settings for diagnosis and treatment of diseases. Expertise in flow cytometry requires advanced theoretical and practical knowledge, including instrument operation, data analysis, and interpretation.

Immunoassay refers to a biochemical technique used to detect and quantify specific substances, typically proteins or hormones, in a sample using the principles of immunology. This skill involves the use of antibodies that specifically bind to the target analyte, allowing for the measurement of its concentration through various methods such as enzyme-linked immunosorbent assay or radioimmunoassay. Knowledge of Immunoassay is applied in clinical diagnostics, research, and quality control to monitor health conditions, evaluate therapeutic responses, and ensure product safety.

Toxicology refers to the study of the effects of chemicals, substances, and toxins on living organisms and the environment. This skill encompasses the assessment of toxic substances, their mechanisms of action, and the evaluation of exposure risks. Knowledge of Toxicology is used to inform safety regulations, develop antidotes, and guide public health decisions by analyzing the potential hazards associated with various chemicals and their interactions.

Virology is a specialized field of study that focuses on the study of viruses, including their structure, classification, behavior, and evolution. It is a multi-disciplinary field that includes aspects of cell biology, immunology, genetics, and microbiology. Virologists use various techniques and technologies to study viruses and their interactions with host cells, as well as the development of vaccines and antiviral drugs. The ultimate goal of virology is to better understand and control the spread of viral diseases.
