The monoclonal antibody 67D3 recognizes human heart-type fatty acid-binding protein (H-FABP) of both natural and recombinant origin. The H-FABP protein is derived from the human FABP3 gene. FABPs are small intracellular proteins (~13-14 kDa) with a high degree of tissue specificity that bind long chain fatty acids. They are abundantly present in various cell types and play an important role in the intracellular utilization of fatty acids, transport and metabolism. There are at least nine distinct types of FABP, each showing a specific pattern of tissue expression. Due to its small size, FABP leaks rapidly out of ischemically damaged necrotic cells leading to a rise in serum levels. Ischemically damaged tissues are characterized histologically by absence (or low presence) of FABP facilitating recognition of such areas. H-FABP is localized in the heart, skeletal and smooth muscle, mammary epithelial cells, aorta, distal tubules of the kidney, lung, brain, placenta, and ovary. Furthermore, this antibody is useful for the purification of H-FABP.

  • Application:
    F, IA, IP, W
  • Application Notes:
    IP: Biotinylated 67D3 was immobilized on streptavidin beads and added to serum to immunoprecipitate H-FABP (Ref.3).
    W: Reduced sample treatment. The band size is ~15 kDa (Ref.2).
    F: Permeabilization was done in cold acetone with 0.5% hydrogen peroxidase for 10 min, after drying and washing, antibodies were incubated for 30 minutes.
  • Positive Control:
    Heart cells, recombinant human H-FABP
  • Negative Control:
    Tonsil tissue
  • Use:
    Dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:50.
