universal sequence

universal sequence

[¦yü·nə¦vər·səl ′sē·kwəns]
(physics)
A sequence of periodic states which reappear as a parameter governing a mapping is varied after the mapping has undergone a transition to chaos by a sequence of period-doubling bifurcations, and which have a particular order that does not depend on the details of the mapping, within certain limits.

However, recently developed novel methods for universal sequence dependent (USD) NAT are superior to conventional approaches in that they employ standardized fluorogenic reagents that provide cost-efficient detection of various targets.
To amplify translocation-specific transcripts present in leukemia cells, primers contained sequences specific to those flanking the junction of fusion genes as well as the T7 and SP6 universal sequence portion.
The universal sequences of primers used for the forward primer was T7 and the reverse primer were slightly modified RP2 or M13R.
Because the length bias of the shotgun sequencing reads was suspected to derive from the PCR, one could potentially ligate universal adaptors to the ends of plasma DNA and then perform PCR amplification against the universal sequences to enrich the fetal DNA fraction.
Although only 12 universal sequences were used for this assay, empirical validation of the full 100-plex array established its potential as a highly specific sorting tool for multiplex analysis of up to 50 biallelic SNPs or 100 analytes.
