  • 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

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

Customer reviews and Q&As


Thank you for your inquiry.

I contacted the specialists in the lab and they provide the following information:

1.) The ratio of FITC to Ig is between 10:1 and 20:1.

2.) There is no modification on IgG to create additional amino groups. We used existing primary amino groups on IgG to make a covalent thiourea bond between activated FITC and the primary amino group present on IgG molecule. We protect the Fab amino groups by favoring the amino groups on Fc region to cross react with active FITC.

Charged groups in the antibody were not measured and will also depend on the buffer that is used.

3.) Since there is no spacer used between FITC and IgG the distance between IgG and FITC is the thiourea bond. So the size of the conjugate will be the size of the antibody plus the FITC molecule without an extra spacer.

I hope this information is helpful and wish you good luck with your research.
