Jasco J-715 Circular Dichroism

Circular Dichroism measures the difference in absorption coefficients of an optically active sample for left and right circularly polarized light. It is the method of choice for the determination of conformational details, such as protein secondary and tertiary structure, to monitor folding or binding and to assess purity of optically active substances (polymers, pahrmaceuticals, etc..). A circulating bath temperature control is available.
