Otx2 in BG01V Human Embryonic Stem Cells. Otx2 was detected in immersion fixed BG01V human embryonic stem cells differentiated to ectoderm using Goat Anti-Human Otx2 Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF1979) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Streptavidin (red; Catalog # NL999) and counterstained with DAPI (blue). Specific staining was localized to nuclei. Cells were co-stained using anti-Tubulin (Catalog # NB600-506, Novus Biologicals) and NorthernLights™ 493-conjugated AntI-Rat IgG Secondary Antibody (green; Catalog # NL015).

Otx2 is a member of the bicoid subfamily of homeodomain-containing transcription factors. It may play a role in brain and sensory organ development (1). Isoform a differs from isoform b by having an eight amino acid residue insertion between P32 and A33 of Otx2b.
