Used in biomedical research to measure levels of vasoactive intestinal peptide (VIP) in mouse samples. Helps study neuroimmunological functions, inflammatory responses, and neurological disorders in mouse models. Commonly applied in studies of circadian rhythms, asthma, sepsis, and autoimmune diseases where VIP plays a regulatory role. Enables researchers to quantify VIP concentration in plasma, serum, or tissue homogenates with high sensitivity and specificity. Supports investigation into the role of neuropeptides in immune modulation and central nervous system signaling.
