Our Abpromise guarantee covers the use of ab213328 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. Detects a band of approximately 70 kDa (predicted molecular weight: 67 kDa).|
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.

All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution
Developed using the ECL technique.
Predicted band size: 67 kDa
Observed band size: 70 kDa why is the actual band size different from the predicted?
Blocking/Dilution buffer: 5% NFDM/TBST.
Exposure time: Lane 1: 10 seconds; Lane 2/4: 1 second; Lane 3: 3 seconds.
The observed molecular weight is consistent with the literature (PMID: 18525461).
Immunofluorescent analysis of 4% paraformaldehyde-fixed. 0.1% Triton X-100 permeabilized Hepa1-6 (mouse hepatoma epithelial cell line) cells labeling alpha 1 Fetoprotein with ab213328 at 1/100 dilution followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining on Hepa1-6 cell line.
The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) (ab195889) (red) at 1/200 dilution.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution.
Flow cytometric analysis of 4% paraformaldehyde-fixed Hepa1-6 (mouse hepatoma epithelial cell line) cell line labeling alpha 1 Fetoprotein with ab213328 at 1/500 dilution (red) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) at 1/2000 dilution was used as the secondary antibody.
