Precision CD Spectroscopy Solutions for Secondary Structure Analysis

Advanced circular dichroism spectroscopy tools for protein and
biomolecule characterization across life sciences and biotech.

Advanced Circular Dichroism (CD) Spectroscopy Systems

Circular Dichroism (CD) Spectroscopy is a powerful technique used to study the secondary structure and conformational changes of chiral molecules, particularly proteins and nucleic acids. By measuring the differential absorption of left- and right-handed circularly polarized light, researchers gain valuable insights into folding, stability, and interactions at the molecular level.

CD Spectroscopy is crucial for structural biology, protein formulation, and biosimilar development. Its applications span from academic research to biopharmaceutical quality control.At Physi Analytica, we provide state-of-the-art CD Spectroscopy technologies and services to B2B clients across North America. As a leading provider, we offer integrated solutions combining reliable instrumentation, expert guidance, and scalable systems tailored for industry needs.
