    • This invention relates to detecting nucleic acids. It employs a double-stranded oligonucleotide probe comprising i)a first probe comprising a first label moiety capable of emitting a measurable signal, and ii) a second probe being partially complementary with the first probe and comprising a second label moiety capable of interacting with the first moiety when brought in close proximity with each other, the second moiety being a quencher or acceptor of emission of the first moiety. The first or second probe comprises a sequence being complementary to that of a target nucleotide, and the second or first probe, respectively, comprises a sequence being complementary to a complement of the target nucleotide sequence of the nucleic acid to be detected. The first and the second moieties are attached to the first and second probes respectively in a manner wherein the distance between the first and second moieties is not more than 7 base pairs apart. The complementary sequences of the double-stranded probe is shorter than the full sequence of both the first and second single-stranded probes. The first and second probes have a higher Tm when hybridized with the target nucleotide sequence compared to the Tm of the double-stranded probe. The intensity of the signal of the first label when the first probe is not hybridized to the second probe is higher or lower than the intensity of the signal of the first label when the first probe is hybridized to the second probe. This invention also relates to oligonucleotides for determining Chlamydia trachomatis.
    • 本发明涉及检测核酸。 其采用双链寡核苷酸探针,其包含i)第一探针,其包含能够发射可测量信号的第一标记部分,和ii)与第一探针部分互补的第二探针,并且包含能够与 当第一部分彼此靠近时,第二部分是第一部分的发射的猝灭剂或受体。 第一或第二探针包含与靶核苷酸互补的序列,第二或第一探针分别包含与被检测核酸的靶核苷酸序列的互补序列互补的序列。 第一和第二部分分别以第一和第二部分之间的距离不超过7个碱基对的方式连接到第一和第二探针。 双链探针的互补序列比第一和第二单链探针的全序列短。 当与靶核苷酸序列杂交时,与双链探针的Tm相比,第一和第二探针具有更高的Tm。 当第一探针不与第二探针杂交时,第一标记的信号的强度比第一标记与第二探针杂交时的第一标记的信号的强度高或低。 本发明还涉及确定沙眼衣原体的寡核苷酸。

    • This invention concerns a method for the assessment of bone fragility and fracture risk, or osteoporosis, in a person. In said method, the concentration of gamma-carboxylated osteocalcin (COC) and optionally also the concentration of intact or total osteocalcin (IOC or TOC, respectively) in a body fluid sample of said person is measured. The concentration of gamma-carboxylated osteocalcin (COC) so obtained is compared to the mean concentration of gamma-carboxylated osteocalcin (mean COC) in similar body fluid samples of the population of the same age and sex. Alternatively, the determined ratio COC/IOC or COC/TOC for said person, is compared to the mean ratio COC/IOC or COC/TOC, (mean ratio COC/IOC or mean ratio COC/TOC) determined from measurements in similar body fluid samples of the population of the same age and sex. A measured COC that is lower than the mean COC is used as indication of osteoporosis, bone fragility or increased risk of bone fracture in said person. Preferably, a determined ratio COC/TOC that is lower than the mean ratio COC/TOC is used as indication of osteoporosis, bone fragility or increased risk of bone fracture in said person. The invention concerns further kits for use in the assessment according to this invention.
