Heterogeneous enzyme conjugates lead to poor repeatability and low detection sensitivity.

The conjugate product may impair the activity of enzymes and antibodies and reduce their stability.

Each test item requires independent optimization, while site-directed conjugation only needs one buffer to meet the stability requirements of all enzyme conjugates.

As a world-leading upstream platform enterprise for in vitro diagnostics, DIA-UP Biotech has focused on core biological raw materials for diagnostic reagents for more than ten years, and is a professional supplier of special protein and small-molecule raw materials. Through independent R&D innovation and tackling key technical challenges of raw materials by our core technical team, we have successfully developed more than 30 kinds of SDC™ antibody conjugate series products, which are widely used in sex hormones, thyroid function, myocardial markers, cytokines, tumor biomarkers and other fields. With excellent stability, outstanding anti-interference capacity, import-equivalent precision and simplified production process, it realizes convenient site-directed conjugation of antibodies and alkaline phosphatase, and accelerates the production optimization of chemiluminescence products.
