Application: AlphaScreen®
- Competitive assay for measuring cAMP
- Detection of fluorescence signals
The AlphaScreen® and AlphaLISA® are bead-based assay technologies used to study bimolecular interactions in a microplate format. ALPHA is an acronym for Amplified Luminescent Proximity Homogeneous Assay and is a versatile technology used to detect and quantify a broad range of analytes in complex biological processes¹.
Plate Types
White Pigmented Plates White pigmented plates are optimized for luminescence measurements. Because of the white coloration, the plates show a maximum reflection of the luminescence signals and minimize well-to-well crosstalk. White plates are available in standard, low volume, or with transparent bottom. Black Pigmented Plates Black pigmented plates are optimized for fluorescence measurements. The plates show a minimal auto-fluorescence because of the black pigmentation, especially in the lower wavelengths, as well as minimized crosstalk between the wells. Black plates are available as standard, low volume or with transparent bottom.
