Our Abpromise guarantee covers the use of ab169552 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000 - 1/10000. Detects a band of approximately 70 kDa (predicted molecular weight: 68 kDa).|
|IHC-P||1/50 - 1/100.|
|ICC/IF||1/100 - 1/250.|
|IP||1/10 - 1/100.|
ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
FunctionBinds 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 specificityPlasma. Synthesized by the fetal liver and yolk sac.
Sequence similaritiesBelongs to the ALB/AFP/VDB family.
Contains 3 albumin domains.
Developmental stageOccurs 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.
modificationsIndependent studies suggest heterogeneity of the N-terminal sequence of the mature protein and of the cleavage site of the signal sequence.

Immunoprecipitation. ab169552 at 1/1000 staining alpha 1 Fetoprotein in HepG2 cell lysate immunoprecipitated using ab169552 at 1/10. Predicted band size : 68 kDa.
Flow Cytometry analysis of HepG2 (human hepatocellular carcinoma) cells labeling alpha 1 Fetoprotein with purified ab169552 at 1/50 dilution (red). The secondary antibody was Goat anti rabbit IgG (Alexa Fluor® 488) at 1/2000 dilution. A Rabbit monoclonal IgG (Black) was used as the isotype control and cells without incubation with primary antibody and secondary antibody (Blue) were used as unlabeled control.
