    FAM109B Antibody (F-7) is a mouse monoclonal IgG2a antibody that detects FAM109B in mouse, rat, and human samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). FAM109B, also known as IPIP27B, Sesquipedalian-2, or Ses2, is a 259 amino acid protein that plays a crucial role in cellular processes by localizing to early and recycling endosomes, the trans-Golgi network, and macropinosomes, which are essential for intracellular trafficking and signaling. FAM109B presence in these compartments is vital for maintaining cellular homeostasis and facilitating membrane protein recycling, thereby influencing various signaling pathways. FAM109B forms homodimers and heterodimers with FAM109A, and both proteins interact with the C-terminal region of inositol polyphosphate 5-phosphatases OCRL1 and Inpp5b. Disruptions in these interactions are implicated in the pathology of Lowe syndrome and type 2 Dent disease, conditions characterized by significant ocular, renal, and neurological defects. Anti-FAM109B antibody (F-7) is an invaluable tool for researchers studying these diseases and the underlying mechanisms of endosomal trafficking.

    Can FAM109B (F-7): sc-390442 monoclonal antibody be used to stain formalin-fixed, paraffin-embedded (FFPE) tissue sections?

    Asked by: Germaine
    Thank you for your question. Yes, FAM109B (F-7): sc-390442 has been validated for use in IHC with paraffin-embedded sections. We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
