General Terms and Conditions
Definition and Characteristics of Analog Bases Analog bases are chemically modified variants of the natural nucleotides—adenine (A), cytosine (C), guanine (G), and thymine (T)—that retain their ability to form complementary base pairs while exhibiting distinct chemical and structural properties. Within sequencing workflows, such modifications can minimize amplification bias, improve detection through enhanced fluorescent signaling, or
Why choose alternative dyes instead of "genuine" dyes? First, they are cheaper, and second, they can give the same results. Another reason is that the number of suppliers who can provide modified oligonucleotides is restricted - only a patent or a licence owner is usually allowed to produce them.
