Stability & Storage

Store at 2-8°C away from light; 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 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.

Guidelines

1. This experiment is light-sensitive; ensure all operations are performed in the dark. It is recommended to conduct preparation, sample addition, and incubation steps under green light (illuminance below 100 LUX). 2. This product is compatible with multi-functional microplate readers equipped with an Alpha detection module. 3. Vortex thoroughly before use. Alternatively, briefly centrifuge (2000×g, 5–10 seconds) to ensure complete retrieval. 4. It is recommended to use the company's accompanying dilution buffer for reagent preparation and sample dilution. If additional components are required, they can be directly added to this dilution buffer. 5. To ensure comparability of experimental data across different batches, strictly control incubation temperature and duration. 6. Avoid generating bubbles during sample addition.

Worth it
These chap sticks are absolutely massive, it’s so soothing to chapped lips and I’m sure they will last a while. The texture is creamy and light on the skin. I’ll definitely be ordering more down the road

All it claims to be!
This product is all it claims to be!! Very smooth, buttery and hydrating. I do not enjoy the vanilla scented one. It has cinnamon in it which I was not expecting based on the description. If it was plain vanilla, I would definitely enjoy it more. I will probably buy the honey one over any of these other scents.
