Multi-channel microfluidic lectin-based barcode bioassay. This schematic is a representation of an antibody-lectin sandwich assay on a microfluidic chip. It contains parallel units that have a three-valve pump that promotes fluidic mixing in the assay chamber. Glycoproteins are captured by lectins and detected with biotinylated antibodies against the targeted glycoproteins, which are subsequently identified using fluorescently labelled streptavidin.
