SDNSF/MCFD2 in Embryonic Mouse Brain. SDNSF/MCFD2 was detected in immersion fixed frozen sections of embryonic mouse brain (E10, neural tube) using Goat Anti-Mouse SDNSF/MCFD2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2556) at 10 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to secretion.

SDNSF, also known as MCFD2 (multiple coagulation factor deficiency 2), was described as a secreted molecule from adult hippocampal neural stem/progenitor cells (ANSC) that functions as an autocrine/paracrine factor to maintain neurogenesis in the central nervous system. It is also a component of the MCDF2-LMAN1 (Mannose-binding lectin-1, also known as ERGIC-53) complex that functions as a specific cargo receptor for the ER to golgi transport of proteins. Mutations in MCFD2 causes factor 5 and factor 8 combined deficiency. Human SDNSF shares 84% and 82% amino acid sequence identity with rat and mouse SDNSF, respectively.
