The XploRA INV combines the exclusive automation features and small footprint of the standard XploRA™ Raman microscope with the unique sampling capabilities of an inverted microscope, especially important for demanding biological applications. These applications include:

cell research
disease detection
characterisation of drug-cell interactions
pharmaceutical verification of intercellular activities

In addition, the inverted geometry allows easy incorporation of AFM units for combined Raman-AFM and TERS (Tip Enhanced Raman Spectroscopy) for highest spatial resolution sample visualisation.

The open structure of the XploRA INV also permits the use of virtually all options and add-ons for inverted microscopes, including micro manipulators and “optical tweezers”, specific enclosures for cell applications, etc.

The XploRA INV also offers the option to integrate the unique scanning capabilities of HORIBA’s patented DuoScan for rapid spectroscopic multichannel Raman imaging, as well as the new 3D FCI (Fast Confocal Imaging) module, which allows ultra-fast fluorescence imaging for visualisation and verification.

Assessing Biotherapeutics Stability using Raman Spectroscopy

We have measured solutions of lysozyme under conditions known to effect its physical state in order to investigate the potential of Raman spectroscopy as a non-invasive and label-free tool to assess protein formulation stability. Results from this study identified specific Raman signature bands in this protein that can be used to identify individual amino acid residues that are reflect structural changes in proteins.
