- When detecting DNA in complex biological media, uninteresting DNA can interfere.
- In 1990, innovators at Firebird solved this problem, developing an Artificially Expanded Genetic Information System (AEGIS)TM.
By shuffling hydrogen bond donors and acceptors, the Z:P, K:X. and S:B pairs were created.
The complete AEGIS expanded alphabet. Different heterocycles implement the various AEGIS hydrogen bonding patterns. Shown are our most popular heterocycles.
