Description

Vasotocin, 1-Desamino-Fluorescein-Lys(4)-Arg(8)- is a synthetic, fluorescently labeled analog of the neurohypophysial hormone vasotocin, designed for advanced biochemical and pharmacological research. This compound is engineered to provide a powerful tool for studying receptor binding, cellular uptake, and localization mechanisms due to its integrated fluorescein reporter. It is primarily utilized by research scientists and pharmaceutical developers in the fields of neuroscience, endocrinology, and drug discovery, where precise tracking and visualization of peptide interactions are critical.

Application

• Biochemical Research: Used as a high-affinity, fluorescent tracer for vasotocin and vasopressin receptor binding assays.
• Cellular Imaging: Enables visualization of peptide internalization, receptor trafficking, and subcellular localization in live or fixed cells.
• Pharmacology Studies: Serves as a key reagent in high-throughput screening (HTS) campaigns to identify agonists or antagonists for related receptors.
• Neuroscience Investigations: Applied in studies of social behavior, stress response, and fluid homeostasis mechanisms in model organisms.
• Diagnostic Development: Potential use in the development of fluorescence-based diagnostic kits or biosensors.
• Method Validation: Acts as a reference standard in analytical method development for peptide quantification via HPLC or LC-MS.
