General notes
ab271896 is the carrier-free version of ab133617.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
This product is a recombinant monoclonal antibody, which offers several advantages including:
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free production
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.
Mouse, Rat: We have preliminary internal testing data to indicate this antibody may not react with these species. Please contact us for more information.

Applications
The Abpromise guarantee
Our Abpromise guarantee covers the use of ab271896 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application | Abreviews | Notes |
---|---|---|
Flow Cyt (Intra) |
Use at an assay dependent concentration.
ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody. |
|
WB |
Use at an assay dependent concentration. Detects a band of approximately 70 kDa (predicted molecular weight: 68 kDa).
|
|
IHC-P |
Use at an assay dependent concentration. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
See IHC antigen retrieval protocols. Heat up to 98°C, below boiling, and then let cool for 10-20 min. |
|
IP |
Use at an assay dependent concentration.
|
|
ICC/IF |
Use at an assay dependent concentration.

Target
-
Function
Binds 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 specificity
Plasma. Synthesized by the fetal liver and yolk sac. -
Sequence similarities
Belongs to the ALB/AFP/VDB family.
Contains 3 albumin domains. -
Developmental stage
Occurs 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. -
Post-translational
modificationsIndependent studies suggest heterogeneity of the N-terminal sequence of the mature protein and of the cleavage site of the signal sequence.
