Pyrosequencing is a method of DNA sequencing (determining the order of nucleotides in DNA) based on the sequencing by synthesis  principle.It differs from Sanger sequencing, in that it relies on the detection of pyrophosphate release on nucleotide incorporation, rather than chain termination with dideoxynucleotides.t was renamed to Biotage in 2003. The pyrosequencing business line was acquired by Qiagen in 2008. Pyrosequencing technology was further licensed to 454 Life Sciences. 454 developed an array-based pyrosequencing technology which has emerged as a platform for large-scale DNA sequencing.
Pyridine is a basic heterocyclic organic compound with the chemical formula C5 H5 N. It is structurally related to benzene, with one methine group (=CH-) replaced by a nitrogen atom.The pyridine ring occurs in many important compounds, including azines and the vitamins niacin and pyridoxal.he nitrogen center of pyridine features a basic lone pair of electrons. Because this lone pair is not part of the aromatic ring, pyridine is a base, having chemical properties similar to those of tertiary amines. The pKa of the conjugate acid is 5.25.
