Inflammation is accompanied by increased endothelial chemokine production and adhesion molecule expression, which may result in an extensive neutrophil infiltration.  As such, the search for novel anti-inflammatory substances able to downregulate these parameters, as well as the tissue damage, holds therapeutic promise. Here we describe how Alpha Technology, a bead-based, homogeneous assay for studying molecular interactions in a microplate format, has been used to detect anti-inflammatory metabolites from cyanobacteria in human endothelial cell-based in vitro assays. We show the quantification of cytokines (TNF-alpha) down to picogram levels with Molecular Devices' SpectraMax® Paradigm® Modular Multi-Mode Reader.  Alpha Technology can be performed on the SpectraMax Paradigm Reader in various plate formats ranging from 96-well to 1536-well.
