Background
Homogeneous Immuno Chemiluminescence Assay (HICA) is a homogeneous immunoassay method based on energy transfer between donor beads and acceptor beads in close proximity, resulting in luminescence.
Donor beads recognize protein 1 (Tag1 label), while acceptor beads recognize protein 2 (Tag2 label). When protein 1 binds to protein 2, the distance between the beads becomes less than 200nm. Upon excitation at 680nm, the donor beads generate singlet oxygen, which diffuses to the acceptor beads. The acceptor beads then undergo a redox reaction, emitting light at 615nm. The signal intensity is directly proportional to the strength of the protein interaction.
This product features a simple operation process, requiring no washing, and offers fast results with high sensitivity. It is capable of detecting weak interactions.
