Description

Vasopressin,-(1-(2-Mercapto)Propionic Acid)-N(6)-Carboxyfluorescein-8-Lys- is a sophisticated, fluorescently labeled derivative of the neurohypophysial hormone vasopressin, designed for advanced research and diagnostic applications. This compound is engineered to enable the sensitive detection, quantification, and visualization of vasopressin receptors and binding events in complex biological systems. It is an essential tool for researchers and developers in the fields of pharmaceutical discovery, neuroendocrinology, and diagnostic assay development, where precise molecular tracking is required.

Application

• Fluorescent Receptor Binding Assays (FRET/FP): Used as a high-affinity, fluorescent tracer for studying vasopressin receptor (V1a, V1b, V2) interactions and kinetics in vitro.
• High-Throughput Screening (HTS): Serves as a key reagent in screening campaigns to identify novel agonists or antagonists for vasopressin receptors in drug discovery pipelines.
• Cellular Imaging and Microscopy: Enables the visualization and localization of vasopressin receptors on live or fixed cells using fluorescence microscopy techniques.
• Diagnostic Kit Development: Acts as a critical component in the development of sensitive immunoassays or biosensors for measuring vasopressin levels in clinical or research samples.
• Biochemical Research: Utilized in studies of signal transduction pathways, receptor internalization, and the physiological roles of vasopressin.
• Quality Control Reference Standard: Can be employed as a characterized reference material in the quality control of related pharmaceutical compounds or diagnostic reagents.

Quality Control

Every batch of our fluorescently labeled vasopressin analog is produced and analyzed under strict quality protocols to ensure high purity, consistent performance, and batch-to-batch reproducibility, which are critical for research integrity. Identity and purity are confirmed by advanced analytical techniques including HPLC and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, fluorescence properties, and functional activity data is provided with each shipment to support your regulatory and research documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For long-term stability, store under inert atmosphere if possible.
