Reference: J:19171 Holland PW, et al., In vivo expression of mRNA for the Ca++-binding protein SPARC (osteonectin) revealed by in situ hybridization. J Cell Biol. 1987 Jul;105(1):473-82
Assay type: RNA in situ
MGI Accession ID: MGI:5888671
Gene symbol: Sparc
Gene name: secreted acidic cysteine rich glycoprotein
Probe: pC33.1
Probe preparation: Antisense labelled with S35 RNA
Visualized with: Autoradiography
Assay notes: Probe size was reduced to an average size of 100 bases by limited alkaline hydrolysis. Sections were post-fixed with 4% paraformaldehyde.
