Porvair Sciences Signum™ MB, 96 Round well, F-Bottom, Black, 350 µl 205003-MB

Signum™ MB is a 96-well microplate designed for assay workflows requiring medium-binding polystyrene surfaces. The plate features round wells with a solid F-bottom in black and a 350 µl well working volume, offering reduced well-to-well crosstalk and low background fluorescence for use with top-reading instruments. It is manufactured to standard ANSI/SLAS dimensions and is free of detectable DNase/RNase for routine laboratory applications such as immunoassays and protein adsorption workflows.

Key Features:

• Format: 96-well, round well array
• Well bottom: Solid F-bottom (rounded square at well bottom to reduce wicking)
• Well working volume: 350 µl
• Colour: Black (opaque walls to minimise light scattering and background fluorescence)
• Material / Surface: Medium-binding pure polystyrene
• Standards: ANSI/SLAS footprint; alphanumeric well coding
• Biochemical: Free of detectable DNase/RNase

Advantages:

• Opaque black walls and low-fluorescence polystyrene reduce background signal and well-to-well optical crosstalk for top-reading assays
• Medium-bind surface supports passive adsorption of larger proteins while requiring minimal blocking for many immunoassay workflows
• ANSI/SLAS format and alphanumeric coding ensure compatibility with automated systems and laboratory automation
• Rounded square F-bottom design lowers residual volume and reduces wicking for improved assay consistency
