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.

Too tight at opening
Size: 13 Little Kid, Color: Light Pink
I bought a size larger for my child, and the foot won’t go in. Her other sketchers slides are great. But I do not recommend this model.

Fits good just needs a light ironing.
Good fit with a casual look. These are a nice fit with an almost slim fit width at the bottom. I am a short guy and the 34x28 size fit me great. As I obviously don't have a trim waistline, I like that the bottom of these are narrower than a more dressier pant. The waist of my pants tend to move up and down approx. an inch to inch and a half and slacks tend to get under the heel of the less clunky modern dress casual shoe. Comparison below. Amazon Essentials 34x28 were a lot tighter (like a 32)in the waist and the length seemed loo long.
