ExperimentCircularDichroism

ExperimentCircularDichroism[Samples]Protocol

generates a Protocol object for measuring the differential absorption of left and right circularly polarized light of the Samples.

    
Circular Dichroism (CD, aka Electronic Circular Dichroism (ECD)) measures how samples differentially absorb left and right circularly polarized light radiation, either at a specific wavelength or over a range of wavelengths. In UV-Vis experiment (e.g., ExperimentAbsorbanceSpectroscopy, ExperimentUVMelting etc), samples are exposed to the unpolarized light, where its electric and magnetic fields perpendicular oscillate in all directions perpendicular to the propagation direction of the light. In circularly polarized light, the electric field vector rotates around the propagation direction at a constant magnitude, resulting in the electric field vector appearing to trace a circle throughout one wave frequency. Optically active chiral molecules will preferentially absorb one direction of the circularly polarized light. The difference in absorption of the left and right circularly polarized light can be measured and quantified as absorption bands. CD spectroscopy can probe the secondary structure composition of polypeptides/proteins and determine the tertiary structure class of globular proteins.
    

Experimental Principles

    Figure 1.1: Procedural overview of a CircularDichroism experiment using an Ekko CD plate reader.Step 1:Samples and blanks are loaded to the plate for reading.Step 2 (optional):the sample volume will be measured by the supersonic method to calculate the pathlength.Step 3:Samples are loaded to the instrument.Step 4:The circular dichroism of samples is measured as ellipticity,based on differential absorption of the left and right circularly polarized light of samples.Step 5:Data is plotted and visualized.

Instrumentation

    Ekko

    Figure 2.1.1: In an Ekko CD Microplate Reader, a Xenon Lamp emits the full-spectrum light. The light is then split and diffracted into several beams by passing a grating monochromator to emit non-polarized light. The non-polarized light then passes the polarizer to generate linear polarized light. The linear polarized light then passes through the photoelastic modulator to create both left- and right-hand circular polarized light. Finally, the differential absorbed circularly polarized light. The transmitted light is then directed through a prism that splits the beam into wavelengths from 185 nm to 900 nm as measured by the detector.

Example Calls

    Basics

    Measuring the circular dichroism in specific wavelength range or at some specific wavelengths
    Use BlankAbsorbance and EmptyAbsorbance options to generate protocol without blank and and empty well scans.
    Use Blanks and BlankVolume options to specify the unique blank buffer during the experiment.

    Molar Ellipticity

    The resulting spectra are in ellipticity (mdeg). To generate data in molar ellipticity, specify the CalculatingMolarEllipticitySpectrum, Analyte, AnalyteConcentration in order to auto calculate the molar ellipticity in resulting spectra.

    Enantiomeric Excess

    To calculate the enantiomeric excess of an unknown sample, submit two standard samples and the unknown samples. Specify each standard sample with their known enantiomeric excess value in the EnantiomericExcessStandards option and specify which wavelengths should be used to calculate the enantiomeric excess in unknown samples EnantiomericExcessWavelengths option.

Preferred Input Containers

    All data collection is preferred to use a quartz plate. Note the quartz plates are reusable, so samples need to be transferred to ContainerOut to save the sample after the experiment.
    Data collection at a visible wavelength region (400 nm to 900 nm) can use standard SBS shallow well plates.

Data Processing

    The data can be viewed by PlotCircularDichroism:
