On most MGI pages, you can access the Recombinase (cre) Activity page from the Search menu as shown in the image at right. From the homepage, you can also access this page by clicking on the "Recombinases (cre)" header or icon.

To find cre recombinase transgenes under the control of a specific promoter, see here

To find cre recombinase transgenes expressed in a specific tissue, structure or organ system here.

1. Click the MGI Recombinase Alleles Report to open the HTML version in a new tab.

2. The MGI recombinase alleles report will appear, sorted alphabetically by Driver in the first column. This indicates the promoter used to drive cre expression.
3. Click the allele symbol (second column) to see the allele detail page, and use the links in the IMSR column to see purchasing information for strains that have been deposited for commercial distribution with repositories indexed by the International Mouse Strain Resource.

4. The allele detail page includes mutation information and a summary of reported recombinase activity. Click the triangles next to row and table features to expand if they are not visible, or for greater detail. Clicking individual check marks will open Recombinase Activity detail pages which display images (where available), patterns of expression, methodology and references associated with each annotation.
5. If you have used this recombinase and have evidence for activity (or no activity) which is not represented in the table, please submit it to MGI using the form located at the Your Observations Welcome button.

1. Click the link to Tab-delimited version or right-click and Save Link As to view or download a list of all recombinase alleles.
