Strain Data Sheet


Strain Information

BRC No.RBRC05658
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.Cg-Siglech<tm1.1Ksat>
Former Common nameSiglech<dtr>, B6-Siglech/DT-GFP KI
H-2 Haplotype
ES Cell lineBruce 4 [B6.Cg-Thy1<a>]
Background strain
Strain developmentDeveloped by Katsuaki Sato, RIKEN Research Center for Allergy and Immunology in 2009. Bruce 4 ES cells derived from B6.Cg-Thy1<a> were used. The mutant mice were backcross to C57BL/6J.
Strain descriptionIRES-DTR-EGFP cassette were inserted in to 3’ untranslated region of Siglech, Siglech sialic acid binding Ig-like lectin H gene. Plasmacytoid dendritic cells (pDCs) from homozygous mutant mice are defect in the transcriptional and cell surface expression of Siglech. In mice with diphtheria toxin (DT) induced specific ablation of pDCs.
Colony maintenanceHomozygote x Homozygote [or Crossing to C57BL/6J(Crlj)]
