Used in immunological research to detect and quantify levels of Pentraxin 3 (PTX3) in biological samples such as serum, plasma, and tissue homogenates from rabbits. This ELISA kit is particularly useful in studies related to inflammation, innate immunity, and cardiovascular diseases, where PTX3 serves as a biomarker. It enables researchers to monitor disease progression, assess therapeutic responses, and investigate the role of PTX3 in host defense and immune regulation. The assay provides high specificity and sensitivity, making it suitable for preclinical studies and veterinary research involving rabbit models.
