The MMRRC's Strain Search Form allows investigators to search for genes or alleles by their name or symbol. Search field options may be combined with each other, e.g. "Cre" Gene/Allele Symbol with "GENSAT" Major Collection. Searches are case insensitive (agouti, Agouti and AGOUTI all match). You may elect a full match (with "equals") or partial matches (using "begins", "contains", or "ends"). Searches for genes include all alleles of the gene, while a search for a specific allele includes only the matching allele.

For additional flexibility in creating SQL "like" text matches, the Gene/Allele Symbol/Name text field also accepts SQL wildcards ("%" and "_") for use with the contains, begins, and ends operators.
