Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: The three selectin genes, Sele, Sell, and Selp, are found within a 300 kb genomic region. To generate double knockouts, ES cells heterozygote for the Selp^tm1Hyn and Sele^tm2Hyn null alleles in trans to each other were targeted a third time. A PGK-puro cassette was used to delete a 2.1 kb region containing the exons encoding the lectin domain and most of the epidermal growth factor domain. Flow cytometric analysis of homozygote leukocytes showed an absence of the L-selectin and P-selectin protein while E-selectin expression was unaffected. Thus, this targeted mutation occurred in cis with the Selp^tm1Hyn allele and in trans with the Sele^tm2Hyn allele. Due to their genomic proximity, the Sell^tm3Hyn and Selp^tm1Hyn alleles should propagate together through the offspring. (J:57973)
