Microlite Microplate 96 Well 280 ul PS White Flat Bottom Case of 50 Plates

Thermo Scientific 7571 Microlite™ 1+ 96-Well White Microplate (Polystyrene)

The Thermo Scientific 7571 is a high-reflectivity 96-well microplate designed for maximum sensitivity in luminescence and fluorescence-based assays. Manufactured from high-purity, medical-grade virgin polystyrene, these solid white plates are engineered to reflect light signal back toward the detector while virtually eliminating well-to-well crosstalk and light piping. The Microlite™ 1+ surface is a medium-binding (hydrophobic) surface, making it ideal for the adsorption of large biomolecules, such as antibodies or proteins, that have large hydrophobic regions. Featuring a standard 96-well footprint and a 280 µl total well volume, the 7571 is the industry choice for luciferase reporter assays, ATP determinations, and chemiluminescent clinical diagnostics.

Technical Performance and Design

• Microlite™ 1+ White Pigmentation: Specially formulated white walls provide a highly reflective surface that enhances signal-to-noise ratios, allowing for the detection of extremely low concentrations of analytes.

• Crosstalk Prevention: The opaque white material prevents light from a high-signal well from bleeding into neighboring wells, ensuring data integrity and accurate quantification across the entire plate.

• Medium-Binding (1+) Surface: The hydrophobic nature of the untreated polystyrene surface is optimized for the passive adsorption of proteins and complexes, providing a stable platform for solid-phase assays.

• Standardized Geometry: Features an ANSI/SLAS compliant footprint, ensuring seamless integration with automated liquid handlers, microplate readers, and robotic stackers.

Key Benefits & Applications

• Luminescence Assays: Specifically optimized for glow and flash chemiluminescence, including luciferase reporter gene assays and ATP bioluminescence.

• Fluorescence-Based Detection: The white surface reduces background fluorescence and "light piping" through the plate bottom, improving performance in top-reading fluorometers.

• Immunoassays (ELISA): Suitable for chemiluminescent ELISA applications where the white background significantly improves the dynamic range of the assay.

• High-Throughput Screening (HTS): The robust, flat-bottom design is ideal for automated plate readers and imaging systems that require precise well positioning.
