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.

ELISA assay is a laboratory technique used to detect the presence and quantity of antibodies or antigens in a sample. It involves using enzymes and antibodies to create a measurable color change, indicating the presence of the specific molecule being measured. This technique requires specialized skills and knowledge to perform, including proper sample preparation, handling, and interpretation of results. ELISA assay is widely used in clinical, research, and diagnostic settings.

Liquid Chromatography Mass Spectrometry (LC-MS) is a specialized technique used for the detection and analysis of chemical compounds. It involves the separation of analytes in a sample using liquid chromatography, followed by the identification and quantification of these analytes using mass spectrometry. LC-MS is commonly used in scientific research, forensic analysis, and pharmaceutical development. It requires specialized skills and expertise, including knowledge of instrumentation, data analysis, and problem-solving.

Nucleic acids are complex molecules that play critical roles in genetic information storage, transfer, and expression. They are composed of nucleotides, which are the building blocks of DNA and RNA. Proper knowledge and understanding of nucleic acids are essential for fields such as genetics, molecular biology, biotechnology, and medicine. The study of nucleic acids involves a range of techniques, including DNA cloning, PCR, gene sequencing, and genetic engineering. Therefore, it is considered a specialized skill in the scientific community.

Real-time polymerase chain reaction (PCR) is a specialized laboratory technique that allows the detection and quantification of specific strands of DNA in real-time. It requires expertise in molecular biology and extensive training in the use of specialized equipment and software. Real-time PCR is used in a variety of applications, including diagnostic testing, genetic research, and drug development.
