Melatonin Analysis Service
Online InquiryWhat is Melatonin?
Melatonin (N-acetyl-5-methoxy-tryptamin) is an indoleamine neurohormone that has been identified in more than 140 plant species in the past 20 years. Studies have shown that melatonin is implicated in almost all of the plant growth and development stages. Additionally, melatonin is reported to effectively protect plant tissues via responses to a variety of abiotic and biotic stresses, including drought, salt, cold, heat, and pathogen infection. Accurate and sensitive detection and quantification of endogenous melatonin enable us to better understand its physiological functions, biological synthesis, metabolic pathways, and regulatory networks. Ultra-performance liquid chromatography (UPLC) coupled with mass spectrometry (MS) has been proved as a reliable approach for analyzing melatonin content in plants because of its high sensitivity, reproducibility and accuracy.
Creative Proteomics offers a specialized melatonin quantification service. With a team of experienced scientists and cutting-edge equipment, Creative Proteomics ensures the delivery of high-quality and reproducible results. Whether you are conducting basic research, clinical studies, or drug development, our service provides valuable insights into melatonin dynamics.
