Embodiment 1

[0089] The extraction of embodiment 1 nucleic acid

[0090] Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU), Mycoplasma hominis (MH) and Mycoplasma genitalium (MG) can be purchased from the Clinical Inspection Center of the Ministry of Health under license conditions, all of which are standard Products for nucleic acid extraction.

[0091] The extraction of nucleic acid is carried out according to the conventional magnetic bead extraction method. In order to adapt to the nucleic acid extraction of the above five microorganisms at the same time, the improvement is as follows: add 90uL nucleic acid extraction solution to 1uL standard (the formula and final concentration are: guanidine isothiocyanate 1.2M, Sodium edetate (pH8.0) 10mM, Tween-20 2% (W / W), sodium perchlorate 1M, ethanol 40% (V / V), Tris-HCl (pH8.0) 10mM) , incubate at 42°C for 10min, then add 10uL D-Beads DNA magnetic bead suspension (50mg / mL, can be purchased from Beijing Aibig...

Abstract

The invention relates to a real-time PCR (polymerase chain reaction) method for quintuply detecting target nucleic acid in a nucleic acid extracting solution in a single PCR reaction vessel, which is used for detecting Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma hominis and Mycoplasma genitalium in a sample.

Description

technical field [0001] The invention belongs to the technical field of nucleic acid detection. Specifically, the invention relates to a multiplex real-time PCR method capable of simultaneously detecting five pathogenic pathogens such as Chlamydia trachomatis, Neisseria gonorrhoeae, Ureaplasma urealyticum, Mycoplasma hominis and Mycoplasma genitalium, It's fast, ultra-sensitive and done in one step. In addition, the present invention also relates to the reagents involved in the above PCR method, such as primers, probes, etc. that are irrelevant to each other, as well as the detection kit used in the above method and the preparation and application of the corresponding detection kit. Background technique [0002] Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU), Mycoplasma hominis (MH), and Mycoplasma genitalium (MG) are the five main pathogens that cause genitourinary system infections, which can cause urethritis, Prostatitis, cervicitis, s...
