Method for determining a concentration of traget nucleic acid molecules, nucleic acid probes for the method and method for analyzing data obtained by the method

A nucleic acid probe for determining a concentration of a target nucleic acid, said probe being labeled with a fluorescent dye, wherein:

• said probe is labeled at an end portion thereof with said fluorescent dye, and
• said probe has a base sequence designed such that, when said probe is hybridized with said target nucleic acid, at least one G (guanine) base exists in a base sequence of said target nucleic acid at a position 1 to 3 bases apart from an end base portion where said probe and said target nucleic acid are hybridized with each other;
• whereby said fluorescent dye is reduced in fluorescence emission when said probe is hybridized with said target nucleic acid.

A nucleic acid probe for determining a concentration of a target nucleic acid, said probe being labeled with a fluorescent dye, wherein:

• said probe is labeled at an end portion thereof with said fluorescent dye, and
• said probe has a base sequence designed such that, when said probe is hybridized with said target nucleic acid, base pairs in a probe-nucleic acid hybrid complex form at least one G (guanine) and C (cytosine) pair at said end portion;
• whereby said fluorescent dye is reduced in fluorescence emission when said probe is hybridized with said target nucleic acid.
