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.
Pyrrolidonyl Arylamidase (PYR) test is a rapid test which is used for the presumptive identification of group A beta-hemolytic Streptococci and Enterococci.PYR test is available in different format. Original PYR test used to take 16-20 hours but now 4-hour broth assay is available, which is described in this post....ankeshwar Acharyafrenbidur@gmail.comAdministratorI am from Nepal, the land of Mt. Everest and where Buddha was born.rocedure of PYR test. 1  With a sterile bacteriologic loop, pick up the growth of two to three morphologically similar colonies and emulsify them in the small volume of PYR broth. 2  Incubate the tube at 35 o C for 4 hours. 3  Add one drop of PYR reagent and observe for color change.
