Used in research settings to detect and quantify levels of human vascular active intestinal peptide (VIP) in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is particularly valuable in studies related to neuroimmunology, inflammatory diseases, and disorders involving the nervous and endocrine systems, where VIP plays a regulatory role. It enables researchers to investigate VIP's involvement in conditions like asthma, chronic inflammation, migraine, and neurodegenerative diseases by providing a sensitive and specific measurement tool. The kit supports high-throughput analysis and is commonly used in clinical research laboratories and pharmaceutical development for biomarker validation.
