Application Abreviews Notes
WB 1/1000 - 1/2000. Predicted molecular weight: 69 kDa.
IHC-P Use at an assay dependent concentration.
IP 1/50.
  • Application notesIs unsuitable for Flow Cyt or ICC/IF.
  • Target

    • FunctionBinds copper, nickel, and fatty acids as well as, and bilirubin less well than, serum albumin. Only a small percentage (less than 2%) of the human AFP shows estrogen-binding properties.
    • Tissue specificityPlasma. Synthesized by the fetal liver and yolk sac.
    • Sequence similaritiesBelongs to the ALB/AFP/VDB family.
      Contains 3 albumin domains.
    • Developmental stageOccurs in the plasma of fetuses more than 4 weeks old, reaches the highest levels during the 12th-16th week of gestation, and drops to trace amounts after birth. The serum level in adults is usually less than 40 ng/ml. AFP occurs also at high levels in the plasma and ascitic fluid of adults with hepatoma.
    • Post-translational
      Independent studies suggest heterogeneity of the N-terminal sequence of the mature protein and of the cleavage site of the signal sequence.
    • Cellular localizationSecreted.
