Stability & Storage

Store at 2-8°C, protected 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 at 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 200 nm. Upon excitation at 680 nm, the donor beads generate singlet oxygen, which diffuses to the acceptor beads. The acceptor beads then undergo a redox reaction, emitting light at 615 nm. The signal intensity is directly proportional to the strength of the protein interaction.

This product features a simple operation process, requires no washing, and offers high speed and sensitivity. It is capable of detecting weak interactions.

Guidelines

1. This experiment is light-sensitive; perform all procedures under light-protected conditions. Preparation, sample loading, and incubation steps are recommended to be conducted under green light (illuminance below 100 LUX). 2. This product is compatible with multi-mode 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. If additional components are required, they may be directly added to this buffer. 5. To ensure comparability of experimental data across different batches, strictly control incubation temperature and duration. 6. Avoid bubble formation during sample loading.

It will shine/glitter up your world.
Color: Silver
My daughter loves this. She has me buy her one every Christmas and uses it to shimmer up everything! Mists out fine particles of glitter as a big poof. It does tend to get everywhere. More even when applying, unlike the brush on applicating ones.

Absolutely good body glitter.
Color: Green
Applies ever so prettily and looks gorgeous against the skin. Easy to use and sparkles for ever. Will stick better if skin is a bit slict, wet, or moist. But still stays on dry skin.

Good quality
Color: Gold
The Etercycle Hair Glitter Spray in Gold is an absolute must-have for girl moms! My daughters love it, and it instantly adds sparkle to their hair and outfits without being too heavy or sticky. The spray goes on evenly, dries quickly, and washes out easily, which is a huge bonus for me. We’ve used it for birthdays, school spirit days, playdates, and even just for fun around the house—it’s perfect for any occasion where a little extra sparkle is needed. The gold shimmer looks beautiful in both hair and on skin, making it super versatile. If you’re looking for a fun, safe, and easy way to add some magic and sparkle to your kids’ look, this glitter spray is a winner. Definitely keeping this on hand for all our special moments! ✨

So sparkly
Color: Gold
This works so good. I like my glitter to stick all over my body and this will stick as long as you rub it in a little. But there is alot of fallout so be careful where you spray it
