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.

Enzymes are proteins that catalyze (speed up) chemical reactions within living organisms. They are highly specialized and can only catalyze specific reactions. Enzymes are essential for many biological processes, including digestion, metabolism, and DNA replication. They also have many industrial and commercial uses, including in food processing, pharmaceuticals, and laundry detergents. Understanding the structure and function of enzymes is an active area of research in biochemistry and molecular biology.

Fluorescence refers to the emission of light by a substance that has absorbed light or other electromagnetic radiation. This skill involves understanding the principles of light absorption and emission, enabling the identification and analysis of materials based on their fluorescent properties. Knowledge of Fluorescence is utilized in various fields, including biology, chemistry, and materials science, to visualize and quantify substances, track biological processes, and enhance imaging techniques.

Polyacrylamide Gel Electrophoresis refers to a laboratory technique used to separate macromolecules, primarily proteins and nucleic acids, based on their size and charge. This skill involves the preparation of a polyacrylamide gel matrix, through which the molecules migrate when an electric current is applied. Knowledge of Polyacrylamide Gel Electrophoresis is utilized in various applications, including protein analysis, DNA sequencing, and the assessment of molecular weight, enabling researchers to analyze complex biological samples effectively.

Protein Purification refers to the process of isolating a specific protein from a complex mixture, such as cell lysates or biological fluids, to obtain it in a pure form. This skill involves various techniques, including chromatography, precipitation, and electrophoresis, which enable the separation of proteins based on their size, charge, or affinity. Knowledge of Protein Purification is used in research and biotechnology to study protein function, structure, and interactions, as well as in the development of pharmaceuticals and diagnostics.
