Used in environmental and agricultural research to quantify lignin content in soil samples, aiding in the study of soil organic matter decomposition and carbon cycling. Enables researchers to assess plant residue degradation, monitor soil health, and evaluate the impact of land management practices on soil fertility. The ELISA-based method offers high sensitivity and specificity, allowing detection of lignin derivatives even in complex soil matrices. Widely applied in studies related to sustainable agriculture, ecosystem modeling, and climate change research.
