Fluorescence polarization assay. The assay utilizes fluorescence polarization changes of fam labelled model template rnas associated with flupol catalyzed product rna formation. It gives a it gives a direct nearly instantaneous measure of a tracers boundfree ratio. The technique of fluorescence polarization fp is based on the observation that when a fluorescently labeled molecule is excited by polarized light it emits light with a degree of polarization that is inversely proportional to the rate of molecular rotation. The assay is high throughput compatible and can easily be performed in 384 well microplates.

2 topical review fp assay development and practical considerations for the optimization and miniaturization of assays to the ultra high throughput 1536 well format. Fluorescence polarization immunoassay fpia is a class of in vitro biochemical test used for rapid detection of antibody or antigen in sample. It reliably reports on compounds inhibiting rna synthesis readily can be miniaturized to 02 pmolereaction of recombinant active flupol and might provide an attractive choice for drug discovery campaigns. Fluorescence polarization is a technique specially applied to study molecular interactions.

Fluorescence polarization is similar to fluorescence intensity in that it is based on the emission of light by an excited fluorophore. Fpia is a competitive homogenous assay that consists of a simple prepare and read method without the requirement of separation or washing steps. Bodipy dyes generally produce less perturbation of receptor binding affinity and other activity parameters than conventional dyes such as fluorescein and rhodamine.

Fluorescence polarizationfluorescence anisotropy fpfa is a versatile solution based technique that has been widely used to study molecular interactions enzymatic activity and nucleic acid hybridization. A key factor in the performance of fluorescence polarization assays is the extent to which the biological activity of the tracer is perturbed by the dye modification. However samples are excited by polarized light which is selected by specific polarizing filters.
