Used in immunological research to quantify levels of the LL37 antimicrobial peptide in biological samples such as serum, plasma, and tissue homogenates. This ELISA kit enables researchers to study the role of LL37 in innate immunity, inflammation, and host defense against pathogens. It is particularly valuable in investigations related to skin diseases, respiratory infections, autoimmune disorders, and wound healing, where LL37 expression is altered. The assay provides a sensitive and specific measurement, supporting both clinical research and drug development efforts targeting antimicrobial peptides.
