DEFINITION

Classification: 435/462

Involving site-specific recombination (e.g., Cre-lox, etc.):

(under subclass 455) Processes wherein recombination between the nucleic acid and another nucleic acid, or within the nucleic acid, occurs in a site-specific fashion, directed by

a specific enzyme or other specific catalytic agent.

(1) Note. Not proper for this subclass are methods wherein a recombination event is directed by homology or similarity over a significant stretch of each molecule, and wherein the recombination reaction is driven by general recombination mechanisms of the cell. Also not proper for this subclass are random integration methods which are classified according to other elements of the invention.
