Nucleotides are monomeric structural units composed of a sugar moiety, attached to one or more phosphate groups, and a nitrogenous base, which may be cytosine, adenine, guanine, thymine, or uracil[1]. Nucleotides and their analogs are very important biochemical reagents and raw materials in genetic engineering, medicine, agricultural products and scientific research[2].

J&K can supply nucleotides and analogs for your biological research.
