Core Reagents for Biochemical Diagnostics: Enabling Trusted Test Results
Biochemical diagnostics involves enzyme reactions or antigen-antibody interactions, primarily used to measure biochemical indicators, body function markers, and various proteins like enzymes, sugars, lipids, non-protein nitrogen, and inorganic elements. This method is essential in detecting and monitoring various medical conditions.
As the first automated detection method, biochemical diagnostics remains one of the most widely-used techniques in in vitro diagnostics (IVD) today.
At J&K Scientific, we provide high-quality enzyme substrates, buffers & detergents, stain & dyes, preservatives, and other essential materials to support companies in their R&D and production processes. With years of experience in chemical synthesis, purification, and custom formulation, we are trusted by IVD, ELISA, molecular diagnostics, and clinical biochemistry companies worldwide. Our products and service support them the reliability and accuracy of biochemical diagnostic tests.
