At present, the quality of ELISA kits on the market is uneven. How to choose the kit that suits you is particularly important. The following points are available for reference:
First, specificity
The specificity of the ELISA kit is related to the key components of the kit, the antibody pair. If one of the antibody pairs is a polyclonal antibody and the other must be a monoclonal antibody, it is recommended to use a double monoclonal antibody.
Second, sensitivity
Sensitivity reflects the ability of the kit to detect the minimum amount of the substance to be tested. The user can select the appropriate kit according to the amount of the index to be tested in the sample. If the amount of the indicator to be tested is very low, the general kit cannot meet the requirements. A high-sensitivity ELISA kit can be selected.
Third, repeatability
Scientific experiments emphasize repeatability. For general ELISA kits, the intra- and inter-plate variation coefficients should be controlled within 15%.
Fourth, simplicity
In the case of high-quality data, the shorter the experimental time, the more convenient the operation, the easier it is to be welcomed by users! This may also be an indicator of the selection kit.
V. Economics
Imported packaging kits save a lot of logistics and customs clearance costs, compared with foreign original imported reagents, there are relatively large price discounts, and can provide more flexible packaging specifications, especially 48T and other small packages, many customers because of The question of trust in the brand is mainly to choose foreign original imports, but the domestically imported companies are still a very good choice!
Sixth, reputation
A brand is not only famous, but more importantly. Through the industry research company and the network, relevant publicity materials, etc. can find high-quality ELISA kit suppliers, this reflects not only the quality of the product, but also a very strict inspection of the supplier's pre-sales and after-sales service. Currently, the major international ELISA suppliers include R&D cytokine kits, Bender adhesion molecule kits, Cayman arachidonic acid kits, Merck (Linco) endocrine research kits, Invitrogen ( Biosource) ELISA for phosphorylated proteins, animal cytokine ELISA kits, etc. The main domestic ELISA kit suppliers are Xinbosheng Biotechnology Co., Ltd., Shanghai Jitai (Yikesai) and so on.
Seven, literature citation
The literature citation of products, especially the reference of high-quality SCI articles, is a problem that many users are concerned about. This is a very important indicator for the recognition of products in the industry, and it has certain reference for the research of related users.
