What is a homogeneous LiquiChip assay?
FAQ ID -476

A homogeneous LiquiChip Assay is an xMAP assay with no requirement to separate free fluorophores from bead-bound fluorophores.

Since reporter fluorescence is only registered when the measured bead can be recognized as belonging to a defined bead set and as having a defined size, reporter fluorescence is derived from a bead only, and not from unbound fluorophores free in solution. Thus, there is no need to perform wash steps.
