Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

Cre Recombinase (D7L7L) Rabbit mAb (HRP Conjugate) recognizes transfected and transgenic levels of total Cre recombinase protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of bacteriophage-P1 Cre recombinase protein.


This Cell Signaling Technology antibody is conjugated to the carbohydrate groups of horseradish peroxidase (HRP) via its amine groups. The HRP conjugated antibody is expected to exhibit the same species cross-reactivity as the unconjugated Cre Recombinase (D7L7L) Rabbit mAb #15036.

Western Blotting

Western Blotting

Western blot analysis of extracts from 293T cells, mock-transfected (-) or transfected with a construct expressing Cre recombinase (+), using Cre Recombinase (D7L7L) XP® Rabbit mAb (HRP Conjugate).


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).
