Detection of Human MSX1 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line. Gels were loaded with 30 μg of whole cell lysate (WCL), 20 μg of cytoplasmic (Cyto), and 10 μg of nuclear extracts (Nuc). PVDF membrane was probed with 0.1 µg/mL Goat Anti-Human/Mouse MSX1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5045) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band for MSX1 was detected at approximately 40 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
MSX1 in Human Ovarian Cancer Tissue. MSX1 was detected in immersion fixed paraffin-embedded sections of human ovarian cancer tissue using Goat Anti-Human/Mouse MSX1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5045) at 0.3, 1.0 and 3.0 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to nuclei.

MSX1 (Msh homeobox homology 1) is a member of the muscle segment homoebox gene family. MSX1 is involved in limb-pattern formation, craniofacial development, odontogenesis, and tumor growth inhibition. MSX1 functions as a transcriptional repressor. MSX1 has been shown to interact with the linker histone, H1B, and repress transcription of the MyoD promoter. Chromosomal abnormalities involving MSX1 have been associated with the Wolf-Hirschhorn syndrome characterized by heart defects and mental retardation.
