Embodiment 1

[0036] Trichomonas vaginalis specific detection and diagnosis sequence: Trichomonas vaginalis G3 adhesion protein AP51-3 partial gene sequence. See Sequence Listing 1.

Embodiment 2

[0038] According to Example 1 Trichomonas vaginalis G3 adhesion protein AP51-3 partial gene sequence design specific nested PCR detection primers are as follows:

[0039] f 1 :GCCCGTAACTTCAACATCC

[0040] R 1 : TCCTCAACACCGTTCTCGT

[0041] f 2 : AAGGCTCAGGTCTACTGTGGT

[0042] R 2 : ATTGTCTGGGCAACTTCCTCT;

[0043] The above two primers can amplify specific detection gene fragments in different systems (nested PCR), the target bands are bright, and there are no non-specific bands. Realize the purpose of detecting Trichomonas vaginalis.

Embodiment 3

[0045] Trichomonas vaginalis PCR detection kit, the composition structure is as follows:

[0046] (1) DNA lysis solution: a mixed solution containing different concentrations of NaCl, Tris-HCl, EDTA, SDS and proteinase K. The ratio of each concentration is: NaCl 100mM, Tris-HCl (pH 7.5) 20Mm, EDTA 25Mm, SDS 2% (w / v) and proteinase K 0.1μg / μl. The function of the lysate is to lyse the nucleated cells (leukocytes, epithelial cells, etc.) in the urine and digest the proteins in them to release the genomic DNA.

[0047] (2) PCR reaction solution: 4 kinds of dNTPs with a final concentration of 100-300 μM each, primer F with a final concentration of 10-100 pmol / μl 1 R 1 f 2 R 2 , 1.5-4.5mM Mg 2+ concentration. Add 2.0 U of Taq enzyme to each PCR reaction (20 μl), and the reaction solution does not contain Taq enzyme.

[0048] (3) Positive control: The positive control used in the kit of the present invention is Trichomonas vaginalis genomic DNA, and its function is to comp...

Abstract

The invention provides a specific trichomonas vaginalis nested PCR (Polymerase Chain Reaction) detection kit which is used in diagnosis and detection of trichomonas vaginalis. A trichomonas vaginalis G3 attachment protein AP51-3 gene diagnosis sequence is provided, a primer is designed according to the sequence, the sensitivity is improved through optimizing an amplification condition, and an amplification result is directly observed through electrophoretic analysis. The nested PCR detection kit is precise in design, simple and easy to operate, high in sensitivity, strong in specificity, capable of identifying trichomonas vaginalis infection, and accurate and objective in result determination.

Description

technical field [0001] The invention relates to the diagnosis and detection technology of Trichomonas vaginalis, more precisely, provides a specific Trichomonas vaginalis nesting PCR detection kit, which belongs to the technical field of parasite detection. Background technique [0002] Trichomoniasis vaginalis is a non-viral sexually transmitted disease caused by Trichomonas vaginalis. Trichomonas vaginalis mainly causes genitourinary system diseases in men and women; it can also cause miscarriage, premature delivery, premature rupture of membranes, low birth weight infants and perinatal infection in pregnant women; in addition, Trichomonas vaginalis infection can increase the risk of HIV, gonorrhea, etc. The probability of infection of spreading diseases can increase the incidence of cancer in women. [0003] The culture method of Trichomonas vaginalis serves as the gold standard for diagnosis. Diamond's medium is a relatively perfect method for cultivating Trichomonas v...
