What troubles do non directional coupling bring to you

 AP Chemiluminescence

The preparation process of non directional coupling is complex, with high technical requirements, which can easily cause large inter batch differences;

The enzyme coupling products are uneven, resulting in poor repeatability and low detection sensitivity;

Non directional coupling products may damage the activity of enzymes and antibodies, reducing their stability;

Each project of non directional coupling needs to be optimized separately, while directional coupling only requires one buffer to meet the stability requirements of all enzyme conjugates;

As a leading global in vitro diagnostic upstream platform enterprise, DIA-UP Biotechnology has been deeply involved in the core biological raw materials of reagents for more than ten years, and is a professional provider of special proteins and small molecule raw materials. Through independent R&D and innovation by the core technical team, more than 30 SDCTM antibody conjugate series products have been developed, which can easily realize the directional coupling of antibodies and Alkaline phosphatase, and efficiently help optimize the production of chemiluminescence products.
