Anti-COUP-TF1 Antibody

COUP transcription factor 1 (UniProt Q60632; also known as Avian erythroblastic leukemia viral oncogene homolog-like 3, COUP-TF1, COUP-TF I, COUP transcription factor I, EAR-3, Nuclear receptor subfamily 2 group F member 1, V-erbA-related protein 3) is encoded by the Nr2f1 (also known as Erbal3, Tfcoup1) gene (Gene ID 13865) in murine species. COUP transcription factors1&2 (COUP-TFI & COUP-TFII) are two related nuclear orphan receptors implicated in their roles in guiding migrating neurons towards their target regions during brain development. COUP-TFI and COUP-TFII are expressed in distinct and non-overlapping migrating cells in specific pathways in the basal telencephalon of mouse embryos at a stage when interneuron migration is robust. While COUP-TFI appears to control dorsal and ventral migration in the basal telencephalon, COUP-TFII is more specific in modulating tangential migration into the intermediate zone of the cortex. Coup-TFII is also identified as an activator of Prox1 expression in venous lymphatic endothelial cell (LEC) progenitors during early stages of LEC specification and differentiation.

Specificity of the antiserum was confirmed by immunogen blocking in immunohistochemistry on frozen sections (Tripodi, M., et al. (2004). Development. 131(24):6119-6129).

Epitope: N-terminal half

GST-tagged recombinant protein corresponding to the N-terminal half of mouse COUP-TF1.

Anti-COUP-TF1 Antibody is an antibody against COUP-TF1 for use in Western Blotting, Immunohistochemistry, Immunofluorescence, Chromatin Immunoprecipitation (ChIP).

Immunohistochemistry Analysis: An 1:250 dilution from a representative lot detected COUP-TFI in 20 µg of rat cerebral cortex, human cerebellum, and human small intestine tissue.
Immunofluorescence Analysis: An 1:500-1000 dilution of a representative lot detected COUP-TF1 immunoreactivity in the developing brain using paraformaldehyde-fixed cryosections from wild-type mouse E13.5 embryos, but not in embryos with brain region-specific COUP-TF1-knockout, by fluorescent immunohistochemistry (Courtesy of Dr. Michele Studer, Institut de Biologie Valrose, France).
Chromatin Immunoprecipitation (ChIP) Analysis: A representative lot detected COUP-TF1 occupancy at the conserved binding sites along the Rnd2 locus using chromatin preparations from the neocortices of E14.5 mouse embryos (Alfano, C., et al. (2011). Development. 138(21):4685-4697).
Western Blotting Analysis: A representative lot detected a higher COUP-TF1 level in retinal and retinal pigment epithelium (RPE) extracts from 24-week-old mice subjected to prorolonged light exposure (24 h/day) than from mice with normal light exposure (12 h/day). Light stress-induced COUP-TF1 upregulation was also observed in RPE, but not retinal extracts from Ranbp2+/− mice (Cho, K.I., et al. (2010). Dis. Model Mech. 3(9-10):595-604).
Western Blotting Analysis: A representative lot detected a 64 kDa form of COUP-TF1 co-immunoprecipitated with RNABP2 from murine retinal extracts (Cho, K.I., et al. (2010). Dis. Model Mech. 3(9-10):595-604).
Immunofluorescence Analysis: A representative lot detected cortex-specific COUP-TFI-knockout in the developing brain of E11.5 COUP-TFIfl/flEmx1Cre transgenic mouse embryos by fluorescent immunohistochemistry staining of paraformaldehyde-fixed cryosections (Armentano, M., et al. (2007). Nat. Neurosci. 10(10):1277-1286).
Immunofluorescence Analysis: A representative lot detected A representative lot detected COUP-TFI immunoreactivity in paraformaldehyde-fixed frozen coronal sections from wild-type E15.5 mouse embryos, but not from COUP-TFI-knockout embryos (Armentano, M., et al. (2006). Development. 133(21):4151-4162).
Immunofluorescence Analysis: A representative lot detected COUP-TF1 immunoreactivity associated with calbindin-positive GABAergic interneurons, but not reelin-positive Cajal-Retzius cells in the developing cortex by dual fluorescent immunohistochemistry using cryosections from E13.5 and E15.5 mouse embryos (Tripodi, M., et al. (2004). Development. 131(24):6119-6129).
Immunohistochemistry Analysis: A representative lot detected a different COUP-TF1 expression pattern than that of COUP-TF2 in the developing telencephalon of forebrain using cryosections from E13.5 mouse embryos (Tripodi, M., et al. (2004). Development. 131(24):6119-6129).
