Pishtaz - Model PT-AFP-96 - Tumor Marker Elisa Kit - Brochure

Alpha-Feto Protein (AFP) is a 70,000 kDa glycoprotein molecule which is closely related to human albumin both genetically and structurally. AFP is produced initially by the fetal yolk sac in small quantities and then in large quantities by the fetal liver as the yolk sac degenerates. The peak concentration in the fetal serum is approximately 3,000,000 ng / ml, and it is reached at this level within 9 weeks gestation. The concentration then declines steadily to about 20,000 ng / ml at the end of term.
