Fluorescence intensity (FI)

As a result of the illumination, the sample emits light (it fluoresces) and a second optical system collects the emitted light, separates it from the excitation light (using a filter or monochromator system), and measures the signal using a light detector.

Fluorescence Polarization (FP)

Fluorescence Polarization can be used to measure the binding constants and kinetics of reactions that cause a change in the rotational time of the molecules. If the fluorophore is bound to a small molecule, the rate at which it tumbles can decrease significantly when it is bound tightly to a large protein. If the fluorophore is attached to the larger protein in a binding pair, the difference in polarization between bound and unbound states will be smaller

Wavelength Range
400 - 700 nm (320 - 850 nm option)

Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET)

HTRF (TR-FRET) combines two techniques FRET (Fluorescence Resonance Energy Transfer) which is homogeneous and TRF (Time Resolved Fluorescence) which is low background. Advantages of TR-FRET: high sensitivity, high throughput, low false-positive, reliable results and easy protocol.

UV-Visible Absorbance

Molecules containing π-electrons or non-bonding electrons (n-electrons) can absorb the energy in the form of ultraviolet or visible light to excite these electrons to higher anti-bonding molecular orbitals. The more easily excited the electrons (i.e. lower energy gap between the HOMO and the LUMO), the longer the wavelength of light it can absorb.
