General description

The gene encoding α-fetoprotein (AFP) is localized on human chromosome 4. It encodes a plasma glycoprotein that has a molecular mass of 70kDa. It is synthesized along with serum albumin during the development of embryonic yolk sac and the liver.


Purified human α-fetoprotein

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

Store at –20°C. For continuous use, store at 2–8°C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.

Biochem/physiol Actions

α-fetoprotein (AFP) is involved in the regulation of fatty acids in both fetal and proliferating adult liver cells. Its expression is found to be increased in acute liver injuries, indicating active liver regeneration. AFP has been associated with fatty liver disease (FLD), a disease that may lead to cirrhosis and hepatocellular carcinoma. It serves as a tumor marker for HCC (hepatocellular carcinoma).

Other Notes

In order to obtain best results in different techniques and preparations, we recommend determining optimal working concentration by titration test.
