Assay
Reference: J:73775 Byrd N, et al., Hedgehog is required for murine yolk sac angiogenesis. Development. 2002 Jan;129(2):361-72
Assay type: Immunohistochemistry
MGI Accession ID: MGI:2177547
Gene symbol: Pecam1
Gene name: platelet/endothelial cell adhesion molecule 1
Antibody: MEC 13.3
Detection system: Secondary antibody coupled to horseradish peroxidase
Assay notes: The Ihh mutation was either generated in CJ7 or R1 ES cells and these were injected into C57BL/6 mice. Chimeric males were mated to C57BL/6, 129/Sv, or Swiss Webster females. Heterozygotes were maintained on a non-specified background.
Results
