    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of VCre recombinase protein.

    Background

    Cre recombinase is a bacteriophage-P1 enzyme required for maintenance of the phage genome as a monomeric plasmid in the lysogenic state (1,2). This enzyme mediates a site-specific recombination between two 34-base-pair loxP sites. This reaction can be carried out in vitro, indicating that it does not require accessory factors (3). The Cre/Lox system has been used for a number of in vitro and in vivo applications, including targeted gene deletions (4) and gene-specific humanized animal models (5). Resolution of the crystal structure of the Cre-Lox complex revealed that two Cre molecules interact with a single Lox site (6).

    Similar to Cre/Lox, two additional site-specific recombination systems have been identified: VCre/VloxP and SCre/SloxP. Although the structure of their recognition sites are identical, Cre, VCre, and SCre recombinases do not cross-react with each other, allowing for in tandem use (7).
