Used in biomedical research to quantify Neurkinin A levels in biological samples such as plasma, serum, or tissue homogenates. Helps in studying neuroinflammatory conditions, pain pathways, and gastrointestinal disorders where NKA is involved. Supports research on tachykinin signaling and its role in asthma, arthritis, and neurological diseases. Provides a reliable, sensitive, and specific method for detecting NKA in cell culture supernatants and cerebrospinal fluid. Commonly used in preclinical studies and drug development to assess the impact of therapeutic agents on neurokinin release.
