Reference: J:290119 Soleilhavoup C, et al., Nolz1 expression is required in dopaminergic axon guidance and striatal innervation. Nat Commun. 2020 Jun 19;11(1):3111
Assay type: Immunohistochemistry
MGI Accession ID: MGI:8270780
Gene symbol: Oprm1
Gene name: opioid receptor, mu 1
Antibody: anti-MOR1 (#24216)
Detection system: Secondary antibody coupled to Alexa Fluor
Assay notes: Nolz1-/- mutant embryos, in which the coding region of Nolz1 has been replaced by beta-Galactosidase (also referred to as Nolz1<bgal/bgal>). Zfp503<tm1.1Bpb> (neo cassette removed) has been used in the annotations, but it could be Zfp503<tm1Bpb> (neo cassette still present).
Results
Specimen S4h WT: embryonic day 18.5 (more )
Structure Level Pattern Image Note
TS26: corpus striatum Present Regionally restricted S4h WT Oprm1(Mor1) is a striosomal marker.

Specimen S4h Nolz1-/-: embryonic day 18.5; Zfp503tm1.1Bpb/Zfp503tm1.1Bpb (more )
Structure Level Pattern Image Note
TS26: corpus striatum Weak Regionally restricted S4h Nolz1-/- There is a strong reduction of expression in Nolz1-/- mutant striatum.
