METHODS FOR RAPID IDENTIFICATION AND QUANTITATION OF NUCLEIC ACID VARIANTS |
摘要 |
There is a need for nucleic acid analysis which is both specific and rapid, and in which no nucleic acid sequencing is required. The present invention addresses this need, among others by providing a method of nucleic acid amplification of overlapping sub-segments of a nucleic acid followed by molecular mass measurement of resulting amplification products by mass spectrometry, and determination of the base compositions of the amplification products. |

1. A method for analyzing a nucleic acid comprising the steps of:
(a) obtaining a sample comprising nucleic acid for base composition analysis; (b) selecting at least two primer pairs that will generate overlapping amplification products of at least two sub-segments of the nucleic acid; (c) amplifying at least two nucleic acid sequences of a region of the nucleic acid designated as a target for base composition analysis using the at least two primer pairs, thereby generating at least two overlapping amplification products; (d) determining base compositions of the amplification products by;
(i) measuring molecular masses of one or more of the amplification products generated in step (c) using a mass spectrometer; and(ii) converting one or more of the measured molecular masses to base compositions; (e) comparing one or more of the base compositions with a source of reference base composition data for the nucleic acid sequence; and (f) identifying the presence of a particular nucleic acid sequence or variant thereof. |
