Molecular Genetics Core Mission Statement

The Molecular Genetics Service Core assists investigators with routine molecular biology applications and all technologies associated with the production and maintenance of genetically altered mouse strains. By centralizing labor-intensive tasks and providing easy access to gene targeting at vastly reduced costs we remove the burden of setting up such technologies in individual laboratories. 


The services are available to all members of the Department of Ophthalmology and Visual Sciences, including adjunct faculty with primary appoints in other Departments. Anyone holding an NEI grant (regardless of departmental affiliation) is also eligible to use our services.
