PLTP in Mouse Brain. PLTP was detected in perfusion fixed frozen sections of mouse brain (medulla) using Sheep Anti-Mouse PLTP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4918) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cell bodies. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

PLTP (phospholipid transfer protein) is a 65-80 kDa, secreted glycoprotein member of the BPI/LBP family of proteins. It is expressed by multiple cell types, circulates bound to HDL, and mediates the transfer of phospholipids and cholesterol from apoB-containing lipoproteins to HDL. Mature mouse PLTP is 476 amino acids (aa) in length. It contains an N-terminal lipid transfer domain (aa 21-239), a C-terminal HDL-binding domain (aa 263-463), and one essential intrachain disulfide bond (Cys146‑Cys185). There are three potential PLTP splice variants. One shows a deletion of aa 148-493, a second shows a deletion of aa 111-162, and a third shows a deletion of aa 14-33 plus a two aa substitution for aa 184-493. Over aa 18-493, mouse PLTP shares 92% and 83% aa identity with rat and human PLTP, respectively.
