Used in biomedical research to quantitatively measure histatin 5 levels in biological samples such as saliva or oral mucosal fluids. This kit is particularly valuable in studies related to oral health, including research on antimicrobial activity, wound healing in the oral cavity, and the body's defense against fungal infections like candidiasis. It enables researchers to assess immune responses and evaluate the role of histatin 5 in innate immunity, making it a key tool in dental and immunological research.
