DEFINITION

Classification: 435/375

Method of regulating cell metabolism or physiology:

(under subclass 325) Subject matter wherein a particular metabolic activity or physiological trait of the animal cell is nonmutagenically and non-recombinantly altered.

(1) Note. Examples of such activities or traits included in this and the indented subclasses which may be altered or regulated are the differentiation state of said cells, ability of cells to metabolize nitric oxide, cell-to-cell contact, cell cycle synchronization or lack thereof, resistance or sensitivity to particular compounds, etc.

(2) Note. Excluded from this subclass are methods which alter the physiology of cells in a broad or nonspecific manner; e.g., mere culturing in a medium, which promotes normal cell growth and division, or shifting the culture temperature to achieve a general heat shock response.

SEE OR SEARCH THIS CLASS, SUBCLASS:

6, for mutagenic and/or recombinant methods which are part of a selection, assay, or test process.
