Web Information

Fluorescence Polarization (FP)

Fluorescence polarization measurements can provide information on the orientation and mobility of labelled macromolecules in the context of associations such as receptor-ligand interactions, protein-DNA interactions, and enzymatic catalysis.

  • The Panvera Full Range Beacon 202 Variable Temp Fluorescence Polarization System provides a simple, rapid, and sensitive way to study equilibrium binding events and affinities for a range of labelled macromolecules. The instrument is configured with fluorescein filters and variable temperature control.

High Precision: Less than 2 mP standard deviation, at 1 nM fluorescein, for 0.1 ml sample.
High Sensitivity: Accurate to 10-11 M fluorescein in the polarization mode and 10-13 M fluorescein in the intensity mode, for 0.5 ml sample.
Variable Temperature Control: 6-65°C in 1°C increments, ± 1°C.
Sample Volumes and Standard Chamber: Sample volume 100 μl in disposable 6 mm x 50 mm glass test tubes.
Operating Software: Step-by-step prompting for measurement of blanks and samples.
Read Time: Static or Kinetic mode (minimum 6 seconds; number of read cycles variable, for very high precision.)
Programmable Protocols: Up to 99 user-defi ned protocols, password protected.
Output Signals and Printer: RS232 for interface with an IBM-compatible computer (not included); DB25 Parallel for interface with
external parallel, thermal printer (included).

Compatible Spreadsheet Programs
Microsoft® Excel, or Lotus 1-2-3, or into a plotting/curve-fitting program

Sample Format: Single-tube
Overall Dimensions: 20.5" x 14.75" x 9.25" (52.6 cm x 37.8 cm x 23.7 cm)
Weight: 35 lb (15.9 kg)

Excitation Illumination:
Standard Instrument: High-intensity 100 Watt quartz halogen lamp for 360-700 nm excitation.
Red-Range Instrument: Same as standard instrument plus 100 Watt high-intensity mercury lamp for excitation from 254-420 nm. Plus an enhanced photomultiplier tube that increases emission detection range to 900 nm.
Emission Detector: Photomultiplier tube (PMT) with selected high gain, low noise, low drift for 200-700 nm emission detection.
An enhanced PMT that increases the emission detection range to 900 nm is also available in the Red-Range Instrument.
Optics: Six-element quartz optical system focuses excitation energy on the sample and collects focused, emitted fluorescent energy on the PMT detector. Excitation and emission polarizers and fi lters are in collimated light paths for optimum performance.
Optical Filters & Holders: Fluorescein filters standard, in easily accessible, external filter holders. Filter holders accommodate other wavelength fi lters for use with different fluorophores.

Standard Instrument: Film polarizers.
Red-Range Instrument: Glan-Taylor type of prism polarizer.
