Fluorescence correlation spectrometer (FCS) ISS

Alba FCS is a dual channel spectrometer that combines a confocal scanning microscope with fluorescence correlation spectroscopy (FCS) and is optimized for both single-photon and multi-photon excitation.

Applications:
Measurement of molecular dynamics
Measurement of kinetic rate constants
Antibody-antigen interactions
Ligand-receptor interactions
Nucleic acid hybridization
Molecular aggregation and polydispersity
Chemical reactions

Measurement Parameters :

a) When using autocorrelation and cross-correlation functions:
Diffusion coefficient
Diffusion time
Concentration
Triplet state decay time constant
Triplet function
Flow rate
Size of excitation volume
Number of molecules

b) When using Photon Counting Histogram (PCH):
Number of molecules
Molecular brightness
