Abstract
This invention relates to an improvement of the procedure for amplifying a target nucleotide sequence by using an effective amount of a glycine-based osmolyte in the reaction mixture of an amplification procedure. It has been found that the use of a glycine-based osmolyte reduces the appearance of stutter bands in the amplification product allowing for easier detection of the target nucleotide sequence. For example, detection of the target trinucleotide repeat sequence, indicative of Huntington's Disease, is made clearer with the use of a glycine-based osmolyte.
Claims3
In the procedure for sequencing a target nucleotide sequence containing trinucleotide repeats, the improvement comprising adding an effective amount of a trimethylglycine to the reaction mixture of a sequencing procedure wherein fewer sequencing products which do not correspond to the target nucleotide sequence are produced than would be produced in the absence of trimethylglycine.
