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.

Available in three colors
Color: Black
These metal mesh trays come in three colors – black, silver and white. While most mesh organizers are black, it’s nice that two other colors are available that might fit better into your décor. There are no interior dividers, which I find to be not very useful anyway. These do not stack, so the clearance is only limited to the height of any shelf above the tray. The trays are as described in the ad. The trays come with 12 self-adhesive foot pads that are round about 5/8” in diameter and about 2mm thick. These will prevent the trays from scratching whatever they are set upon. The trays will prevent loose objects from falling from your desk or shelf.
