For developing an effective protection against COVID-19 (coronavirus) pandemic is inevitable to understand the protein structures taking part in the process as accurately as possible. The JASCO circular dichroism equipment can provide a relevant help for this purpose. JASCO publications summarising the newest research achievements can be downloaded from the “Library ” section on our website. We are especially proud of the fact that the determination of the protein structures according to the measured spectra was performed based on the BeStSel method developed by the researchers working at the Department of Biochemistry of Eötvös Loránd University (ELTE), Budapest, Hungary.
