The markers generally include, along with a unique sequence preferably including coded section designed to represent one or more factors of interest, primer annealing sequences so that the marker may be amplified and sequenced in the same process and using the same amplification and sequencing primers as for the sample target.

Mutant neq hs dna polymerase derived from nanoarchaeum equitans and its application to hot-start pcr


A dna polymerase (neq dna polymerase) derived from nanoarchaeum equitans is split into neq l and neq s fragments, each of which contains inteins. A neq hot-start (hs) dna polymerase in which the inteins of the neq l and neq s fragments are linked with each other is provided in the form of a precursor of neq dna polymerase.
