Peptide circular dichroism and thermal response
Far-UV circular dichroism (CD) provides a conformational fingerprint related to peptide secondary structure. Matched measurements can help distinguish spectral differences among formulations, batches or reference samples.
Request a technical assessmentResearch questions
- Do the test and reference samples have comparable far-UV spectra?
- Does the spectral profile change with formulation, storage or temperature?
- Does the sample support near-UV or thermal-response measurements?
What the report can include
- Far-UV spectra, blank correction and sample overlays.
- Estimated secondary structure composition when the wavelength coverage and model are suitable.
- Where supported, near-UV fingerprints, temperature-response curves or an interpretable apparent transition temperature.
How to interpret the results
Buffer and sample absorbance can restrict the usable wavelength range. Estimates for short peptides depend on the reference set and model. If a thermal scan has no clear transition, the result can be reported as a temperature-dependent spectral response.
Before sending samples
Provide the molecule, concentration, formulation composition and pH, and the comparison groups. Confirm whether you can supply a matching blank. For temperature studies, describe the target conditions and any known precipitation or aggregation.
