Alpha-fetoprotein (AFP) serves as one of the most clinically significant oncofetal markers in biomedical research, with elevated expression strongly associated with hepatocellular carcinoma and certain germ cell tumors. During normal development, AFP is abundantly produced by the fetal liver and yolk sac, but its expression becomes largely silenced in healthy adult tissues. This expression pattern makes AFP an invaluable marker for studying liver cancer biology, tumor progression, and developmental processes.
This recombinant monoclonal antibody, clone 17G5, offers researchers the reproducibility advantages inherent to recombinant technology. Because the antibody sequence is defined and produced through controlled expression systems, you can expect consistent performance across experiments and over time, eliminating the lot-to-lot variability that can complicate long-term studies or multi-site collaborations. The rabbit host origin combined with affinity chromatography purification ensures high specificity for your target.
Validation studies demonstrate reliable performance in both immunofluorescence and flow cytometry applications using HepG2 cells, a well-established human hepatocellular carcinoma model known for robust AFP expression. Immunofluorescence staining at dilutions between 1:50 and 1:200 reveals clear cytoplasmic localization patterns when counter-stained with DAPI, while flow cytometry analysis shows distinct positive population shifts compared to isotype controls, confirming specific detection of AFP-expressing cells.
The antibody is supplied in a stabilized liquid format containing glycerol for convenient long-term storage at -20°C or -80°C. Whether your research focuses on hepatocellular carcinoma characterization, developmental biology, or biomarker validation studies, this antibody provides a dependable tool for detecting human AFP across multiple experimental platforms.
