Background
Homogeneous Immuno Chemiluminescence Assay (HICA) is a homogeneous immunoassay method based on energy transfer and luminescence between donor beads and acceptor beads at close proximity.
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 protein interaction.
This product features a simple operation process, no washing steps, fast speed, and high sensitivity, making it suitable for detecting weak interactions.

Guidelines
1. This experiment is light-sensitive. Perform all procedures (e.g., preparation, loading, and incubation) under green light conditions (illuminance below 100 LUX).
2. This product is compatible with multifunctional microplate readers equipped with Alpha detection modules.
3. Vortex thoroughly before use. Alternatively, briefly centrifuge (2000×g, 5–10 seconds) to ensure complete sample retrieval.
4. It is recommended to use the accompanying dilution buffer for reagent preparation and sample dilution. Additional components can be directly added to this buffer if required.
5. To ensure comparability of experimental data across batches, strictly control incubation temperature and duration.
6. Avoid bubble formation during loading.
