Used in research to quantify levels of LL-37, a human antimicrobial peptide, in biological samples such as serum, plasma, and tissue homogenates. This ELISA kit helps study the role of LL-37 in immune responses, inflammation, and host defense against pathogens. It is widely applied in immunology and infectious disease research to investigate conditions like psoriasis, rosacea, sepsis, and chronic wounds where LL-37 expression is altered. The assay enables high-throughput, sensitive detection, supporting both clinical and experimental studies focused on innate immunity and inflammatory disorders.
