1. PH
A measure of the hydrogen- ion activity in a solution, expressed as the negative log10 of hydrogen ion concentration on a scale of 0 (highly acidic ) to 14 (highly basic ) with a pH of 7 being neutral.

2. PH
System of measuring the acidity or alkalinity of a substance; refers to the negative logarithm of the hydrogen ion content of the solution. pH values run from 1 to 14; a pH of 7 indicates that a substance is neutral. A value of more than 7 indicates the substance is basic (alkaline) and a value of 11 or more indicates it is very basic and is likely to cause corrosion and/or tissue damage. Likewise, a value of less than 7 indicates that the substance is acidic, and a value of 3 or less indicates it is a strong acid.

3. PH
The negative logarithm of the H+ ion concentration. The pH is a measure of the acidity or basic character of a solution. Since it measures a fraction, the larger the pH number, the less H ions are present in a solution.

4. Phage display (phage display technology)
A set of lab techniques used to identify and isolate specific types of molecules from complex mixtures of millions of compounds. The phage display process works by attaching millions of variations of a given protein or peptide onto the cell surfaces of microorganisms or bacteriophage s to make a library (or a display) and then selecting for the ones which are most useful or interesting. The lab techniques are especially useful for the development of pharmaceuticals and diagnostics.

5. Phagemid
A cloning vector that can replicate either as a plasmid or as a bacteriophage .

6. Phagocyte
Any cell that engulfs and devours another.

7. Phagocytes
White blood cells that can engulf (by phagocytosis) and destroy microorganisms including viruses and bacteria; cells in this category include neutrophils and monocytes.

8. Phagocytosis
* The process by which a cell is engulfed and broken down by another for purposes of defense or sustenance. * The uptake of extracullular materials by the formation of a pocket from the cellular membrane and its subsequent pinching off. Compare endocytosis and pinocytosis .

9. Phagocytosis
A form of endocytosis in which white blood cells surround and engulf invading bacteria or viruses.

10. Phanerogam
A plant with conspicuous reproductive parts; a plant reproducing by seeds. Compare cryptogam .
