Reference: J:88280 Romand R, et al., Complementary expression patterns of retinoid acid-synthesizing and -metabolizing enzymes in pre-natal mouse inner ear structures. Gene Expr Patterns. 2004 Mar;4(2):123-33
Assay type: RNA in situ
MGI Accession ID: MGI:3037229
Gene symbol: Cyp26a1
Gene name: cytochrome P450, family 26, subfamily a, polypeptide 1
Probe: Cyp26a1 cDNA
Probe preparation: Antisense RNA
Assay notes: The probe length was reduced to approximately 150 nucleotides by alkaline hydrolysis.
