Used in biomedical research to measure vasoactive intestinal peptide (VIP) levels in rat samples, this ELISA kit enables quantification of VIP in plasma, serum, or tissue homogenates. It is commonly applied in studies related to cardiovascular function, inflammation, circadian rhythms, and neuroimmunology. Researchers use it to investigate VIP’s role in vasodilation, immune modulation, and nervous system signaling in rodent models. The assay provides high sensitivity and specificity, making it suitable for detecting small changes in VIP concentration during experimental treatments or disease conditions.
