Anti-alpha 1 Fetoprotein antibody [AFP-11] (ab3969)


  • Product nameAnti-alpha 1 Fetoprotein antibody [AFP-11]
    See all alpha 1 Fetoprotein primary antibodies
  • Description
    Mouse monoclonal [AFP-11] to alpha 1 Fetoprotein
  • SpecificityThe antibody reacts with human alpha-Fetoprotein (AFP), an oncofetal antigen of 70 kDa. AFP is a major fetal plasma protein, but is not present in healthy adult tissues. Elevated AFP concentrations in adult plasma may be an early marker of hepatocellular carcinoma or teratoblastoma, while high concentrations in amniotic fluid may indicate severe congenital defects of a fetus.

  • Immunogen

    Full length native protein (purified) corresponding to Human alpha 1 Fetoprotein.



Our Abpromise guarantee covers the use of ab3969 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF 1/200. PubMed: 19497803
IHC-P Use a concentration of 10 µg/ml.
RIA Use at an assay dependent concentration.
Sandwich ELISA Use at an assay dependent concentration.


  • 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.
