A diverse range of biochemical reagents are known for the identification of certain metabolisms and to differentiate between bacteria. Classical biochemical tests are often used to identify microorganisms; the results are seen by color change. In most cases, detection is based on the reaction of an enzyme with a certain substrate. Also, methods to detect certain metabolites by chemical reaction and or complex building techniques are used. CDH Offers a wide range of products in biochemicals, including antibiotics, nucleotides, proteins, peptides, polyamino acids, buffers, lipids, carbohydrates and antibodies used in fundamental research.
