Data Examples
Immunohistochemistry
FABP8 in Human Spinal Cord. FABP8 was detected in immersion fixed paraffin-embedded sections of human spinal cord using 15 µg/mL Human FABP8 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5866) overnight at 4 °C. Tissue was stained with the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue).

Immunohistochemistry
FABP8 in Human Brain. FABP8 was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using Human FABP8 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5866) 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). View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
Detection of Human FABP8 by Western Blot. Western blot shows lysates of human hippocampal and rat spinal cord tissue. PVDF membrane was probed with 1 µg/mL of Human FABP8 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5866) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for FABP8 at approximately 15 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 7.

Background: FABP8/M-FABP

FABP8 (fatty acid binding protein-8; also M [myelin]-FABP, P2 and PMP2) is a 15 kDa (predicted) member of the fatty acid binding protein family, calycin superfamily of molecules. It is found in Schwann cells, presumably on the cytoplasmic face of the plasma membrane where it may contribute to fatty acid transport across myelin. Functionally, FABP8 has a high affinity for U-shaped fatty acids such as oleic and palmitic acid. Human FABP8 is 132 amino acids (aa) in length and exhibits two layers of anti‑parallel beta -strands that envelope a hydrophobic pocket for lipid binding. Arg107 plus Arg127-Ile128-Tyr129 participate in fatty acid binding. Full length human FABP8 shares 87% and 95% aa identity with mouse and rabbit FABP8, respectively.

  • Long Name:
    Fatty Acid-Binding Protein 8
  • Entrez Gene IDs:
    5375 (Human); 18857 (Mouse); 688790 (Rat)
  • Alternate Names:
    FABP8; MFABP; M-FABP; MP2; myelin P2 protein; P2; peripheral myelin protein 2FABP8; PMP2
