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

Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 70 kDa (predicted molecular weight: 68 kDa).
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
ICC/IF 1/100 - 1/250.
IP 1/10 - 1/100.
Flow Cyt 1/50.

ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.

Target

  • Function

    Binds 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 specificity

    Plasma. Synthesized by the fetal liver and yolk sac.

  • Sequence similarities

    Belongs to the ALB/AFP/VDB family.
    Contains 3 albumin domains.

  • Developmental stage

    Occurs 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
    modifications

    Independent studies suggest heterogeneity of the N-terminal sequence of the mature protein and of the cleavage site of the signal sequence.
    Sulfated.
