Mouse Pref‑1/DLK1/FA1 Antibody

Detection of Mouse Pref-1/DLK1/FA1 by Immunohistochemistry

Dlk1 imprinting & expression in the developing pituitary gland from the endogenous locus & TGDlk1-70C transgene.(A) Cross used to generate embryos & postnatal animals in the study. Males inheriting the deleted allele from the mother (maternal Dlk1tm1Srbpa/+ heterozygotes or MATs) were crossed to females hemizygous for the TGDlk1-70C transgene (WT-TG), generating 4 genotypes, WT, WT-TG, paternal Dlk1+/tm1Srbpa heterozygotes (PATs) & mice inheriting a deleted paternal allele & the transgene (PAT-TG). (B) Schematic showing the known splice variants of Dlk1, A-D. Splicing occurs internally in exon 5 of the Dlk1 gene. Dlk1-A & B retain an extracellular cleavage domain (TACE), in Dlk1-C & D this region is spliced out. All versions contain a single pass transmembrane domain (TM). Red arrows indicate location of primers used in (C). (C) Semi-quantitative PCR on embryonic day (E) 18.5 whole pituitary glands from the 4 genotypes shown in (A). Top – primers amplify the exon 4–5 region of Dlk1 & can distinguish splice variants based on size. Bottom – alpha-tubulin (Tuba1a) was amplified as a loading control on each sample. (D) In-situ hybridisation for Dlk1 in the developing pituitary gland from E9.5 to E18.5 in the 4 genotypes shown in (A). Dlk1 expression is indicated by purple staining. Scale bars show 100 µm (E9.5 & E13.5, sagittal sections) & 200 µm (E15.5 & E18.5, frontal sections). (E) Immunohistochemistry (IHC) for DLK1 on frontal sections at E18.5 & postnatal day 21 (P21), counterstained with DAPI. Scale bars = 50 µm.Figure 2—source data 1.Zipped file containing the source data for Figure 2D -gels with cropped areas highlighted & original gel images.
