Used in research settings to quantify levels of human bactericidal peptides, specifically cecropins, in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables scientists to study the innate immune response, particularly the role of antimicrobial peptides in fighting bacterial infections. It is widely applied in immunology and infectious disease research to assess immune activity, evaluate therapeutic interventions, and investigate inflammatory conditions. The assay provides a sensitive and specific means to measure peptide concentration, supporting studies on host defense mechanisms and potential development of peptide-based antibiotics.
