Biological buffers and their role in diagnostic testing
27 May 2026This resource outlines the critical role of biological buffers in maintaining stable pH conditions during diagnostic testing. Discover how buffers protect biomolecules such as enzymes, nucleic acids, and antibodies from pH fluctuations, ensuring accurate and reproducible results.
The resource also covers buffer selection criteria, including pKa, solubility, and temperature stability, alongside their use across key diagnostic applications such as immunoassays, PCR, and sample preparation workflows.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins. Find the best cell and tissue culture products, kits and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.ImmunoassayImmunoassays are laboratory tests that utilize antibody-antigen interactions to detect specific substances. They are widely used in diagnostics for detecting diseases, drug testing, and environmental monitoring. These assays offer rapid, sensitive, and precise detection of biomarkers, making them invaluable in clinical and research labs.
