Gene Information

human ... AFP(174)

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.

Immunogen

Purified human α-fetoprotein

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).

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.

Other Notes

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

Clinical observation of the association between cancer aggressiveness and embryonic development stage implies the importance of developmental signals in cancer initiation and therapeutic resistance. However, the dynamic gene expression during organogenesis and the master oncofetal drivers are still unclear, which
