AFP, Alpha-Fetoprotein

Catalogue number: AF100

Product Type Primary Antibodies
Units1 ml
Application IHC(C
The antibody to alpha-fetoprotein may be used for the detection of AFP in fetal liver, primary liver carcinoma, and in metastases thereof. Most germ cell tumours are AFP-positive, too. Human alpha-fetoprotein (AFP) is synthesized in the embryonic yolk sac and during adult life in the liver. During childhood and youth only very low concentrations are found in blood, but it is found in high quantities in maternal and fetal blood during pregnancy. Exceptionally high concentrations have been found in different failures of fetal development. Tissue transformation as it occurs in primary hepatocarcinoma is accompanied by increased synthesis of alpha-fetoprotein, so that it can be used as an immunohistochemical marker of this disease. Human Alpha-Fetoprotein (no cross-reactivity with HSA, CEA, Ferritin, HCG, and PSA).

Positive Control
Fetal liver

No protease pre-treatment required, but microwave treatment usually will intensify staining. We refer to BIOLOGO's Unmasking Fluid G (Art. No. DE007).

Purified Alpha-Fetoprotein from umbilical cord blood

Working Concentration
(liquid conc.) 1:10 to 1:50

Incubation Time
60 min at RT

Secondary Reagents
We recommend the use of BIOLOGO's Universal Staining System DAB (Art. No. DA005) or AEC (Art.-No. AE005).

Antibody solution in stabilizing phosphate buffer pH 7.3. Contains 0.09 % sodium azide**. The volume is sufficient for at least 100 immunohistochemical tests (100 µl working solution/test). Use appropriate antibody diluent e.g. BIOLOGO Art .No. PU002.
