Used in research settings to detect and quantify the AFP-L2 heteropolymer variant in biological samples, this ELISA kit supports studies related to liver cancer, particularly hepatocellular carcinoma. The assay helps differentiate AFP-L2 from other AFP isoforms, offering improved specificity in identifying aggressive tumor types. It is commonly applied in clinical research to assess disease progression, monitor treatment response, and evaluate recurrence risk in high-risk patient groups. The kit is not intended for diagnostic use but serves as a valuable tool in biomarker validation and oncology-related investigations.
