Particle Generation Rate

A means of expressing hydrogen ion concentration in terms of the powers of 10; the negative logarithm of the hydrogen ion concentration. This is a measure of whether the water is acidic or basic. pH is a measure of the hydrogen ion concentration in the water.

The negative log of the hydrogen ion concentration, is a measure of the concentration of hydrogen ions (H+) in a water-based solution. The more hydrogen ions that are present, the lower the pH and the more acidic the solution.

The pH value of an aqueous solution is a number describing its acidity or alkalinity. A pH is the negative logarithm (base 10) of the concentration of hydrogen ions (equivalent per liter). The pH value of a neutral solution is 7. An acidic solution has a pH less than 7, while a basic solution has a pH greater than 7, up to 14.

The negative log of the hydrogen ion concentration, is a measure of the concentration of hydrogen ions (H+) in a water-based solution. The more hydrogen ions that are present, the lower the pH and the more acidic the solution.

Phytohemogglutinin Lymphocyte-Conditioned Medium

Phytohemagglutinin-stimulated Leukocyte-Conditioned Medium

A virus for which the natural host is a bacterial cell.

A cell that engulfs foreign particles from its surroundings by a process called phagocytosis. The cell releases hydrolytic enzymes from intracellular bodies called lysosomes that partially digest the foreign particle, after which it is further degraded in the phagocyte cytoplasm.
