Data Examples
Detection of Human Otx2 by Western Blot. Western blot shows lysates of IMR‑32 human neuroblastoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Otx2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1979) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Otx2 at approximately 37 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Immunocytochemistry
Otx2 in NTera‑2 Human Cell Line. Otx2 was detected in immersion fixed NTera‑2 human testicular embryonic carcinoma cell line using Goat Anti-Human Otx2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1979) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (yellow, upper panel; Catalog # NL001) and counterstained with DAPI (blue, lower panel).

Detection of Human Otx2 by Simple WesternTM. Simple Western lane view shows lysates of IMR‑32 human neuroblastoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Otx2 at approximately 48 kDa (as indicated) using 10 µg/mL of Goat Anti-Human Otx2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1979) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Otx2
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.
