Potassium phosphate is a reagent with high buffering capacity. It occurs in several forms: monobasic, dibasic and tribasic (K3PO4). Most pH neutral potassium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH.
Potassium phosphate monobasic is typically used as a component for a wide variety of media used in the culture of microorganisms. It is widely used in molecular biology, biochemistry, and chromatography. It is a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate.

Sodium chloride is a commonly used chemical which is found widely in nature. It is considered to be an essential nutrient. Excess amounts of sodium chloride can destroy electrolyte balance and cause death in most animals, including humans.
Sodium chloride is used in a wide variety of biochemical applications, including intravenous fluids (normal saline is 0.9% w/v in water 10), density gradients 3,6, a diluent to increase ionic strength in buffers or culture media and in salt-out procedures in the isolation of DNA. It has also been used in high concentrations for preservation of foods since bacteria cannot grow in high salt conditions. A salt-ice mixture in the ratio of approximately 33 g sodium chloride to 100 g ice (at -1°C) will drop in temperature to as low as -21°C, depending on the rate of stirring and the size of the ice chunks.

Aprotinin is a single chain polypeptide (58 amino-acids) crosslinked by three disulfide bridges, showing competitive and reversible inhibiton of proteolytic and esterolytic activity. Aprotinin forms stable complexes with, and blocks the active sites of serine protease enzymes. It is found in bovine lymph nodes, lung, parotid gland, spleen, liver, pancreas, seminal vesicles, thyroid gland, kidney, mucous membranes of the trachea and esophagus, ovaries, heart, posterior pituitary and cartilage.
Aprotinin is a competitive serine protease inhibitor that inhibits trypsin, chymotrypsin, kallikrein and plasmin. Aprotinin forms stable complexes with and blocks the active sites of enzymes. Binding is reversible with most aprotinin-protease complexes dissociating at pH >10 or < 3.

Aprotinin is used as a proteolytic inhibitor in radioimmunoassays of polypeptide hormones.
