| Stability & Storage | Store away from light at 2-8℃; product shelf life is 12 months. |
Background
Homogeneous Immuno Chemiluminescence Assay (HICA) is a homogeneous immunoassay method based on energy transfer between donor beads and acceptor beads for 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, 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, enabling the detection of weak binding.

```Guidelines
1. This experiment is light-sensitive. Perform all procedures under light-protected conditions. It is recommended to conduct preparation, sample loading, and incubation steps under green light (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 provided by our company for reagent preparation and sample dilution. For special additive requirements, corresponding components can be directly added to this buffer.
5. To ensure comparability of experimental data across different batches, strictly control incubation temperature and duration.
6. Avoid generating bubbles during sample loading.
