Profacgen Launches Fluorescence Polarization Assay for Advanced Protein Interaction Analysis

February 22, 2024

Profacgen, a leading provider of protein-related services and products, is thrilled to announce the release of their cutting-edge Fluorescence Polarization Assay. This innovative assay empowers researchers with a highly sensitive and accurate tool to study protein-protein interactions and gain deeper insights into cellular processes.


Protein-protein interactions are fundamental to numerous biological processes, including signal transduction, enzymatic reactions, and immune responses. Understanding these interactions is crucial for unraveling the mechanisms underlying cellular functions and developing targeted therapies for diseases. The Fluorescence Polarization Assay offered by Profacgen provides researchers with a powerful method to investigate these interactions.


The Fluorescence Polarization Assay is based on the principle of fluorescence polarization, which measures the rotation of a fluorescently labeled molecule in solution. When a protein interacts with another molecule, its rotational movement changes, leading to alterations in the fluorescence polarization signal. By monitoring these changes, researchers can quantitatively analyze protein interactions and determine binding affinities.


One of the key advantages of the Fluorescence Polarization Assay is its exceptional sensitivity and accuracy. The assay can detect even weak protein interactions, making it suitable for studying a wide range of protein systems. Additionally, the assay requires only small sample volumes, minimizing the consumption of valuable research materials.


The Fluorescence Polarization Assay offered by Profacgen is a versatile tool that finds applications in various research areas:

  • Protein-protein interaction studies to identify potential drug targets or investigate mechanisms of disease.
  • Protein-DNA interaction studies for transcriptional regulation.
  • Enzyme kinetics study for the study of mechanism of enzyme action.
  • Small molecule binding studies to identify potential drug candidates or study the mechanism of drug action.


"We are thrilled to introduce our Fluorescence Polarization Assay to the scientific community," said Crystal, the chief marketing staff at Profacgen. "This assay represents a significant advancement in protein interaction analysis, providing researchers with a reliable and sensitive method to study protein interactions and accelerate scientific discoveries."
