Sexually Transmitted Infections (STIs) are infectious diseases mainly spread through sexual contact or related behaviors. They are caused by viruses, Chlamydia, Mycoplasma, bacteria, fungi, protozoa, and parasites. STIs can lead to serious reproductive and systemic health problems. According to WHO, over 1 million STIs are acquired every day worldwide. In 2022, there were about 374 million new cases of four curable STIs. Over 500 million people aged 15–49 live with genital herpes globally. These figures highlight the urgent need for accurate and efficient diagnostics. Multiplex molecular testing allows simultaneous detection of multiple pathogens. It improves diagnostic accuracy and speeds up treatment. This is key for identifying asymptomatic cases and managing mixed infections.

Product Details FAQ Specification Instructions

This assay targets conserved genomic regions of seven STI pathogens, utilizing specifically designed primers and fluorescently labeled TaqMan probes for each. Compared to conventional PCR, this method offers higher automation, speed, sensitivity, and specificity. The assay employs an optimized reaction buffer system and hot-start DNA polymerase to produce a ready-to-use master mix, minimizing manual preparation steps and enhancing operational efficiency. In addition, the human RNase P gene is introduced as a non-competitive internal control to monitor both nucleic acid extraction and amplification processes, effectively preventing false-negative results.


All-in-One Premix

Ready-to-use master mix requires only the addition of sample, significantly reducing hands-on time and minimizing manual errors.

Contamination Control

Incorporates a dUTP/UDG system to effectively prevent carryover contamination between reactions.

High Specificity

No cross-reactivity was observed with a range of non-target pathogens, including Group B Streptococcus, Human Papillomavirus (HPV), Salmonella spp., Pseudomonas aeruginosa, Escherichia coli, Treponema pallidum, Human Cytomegalovirus (CMV), Epstein-Barr Virus (EBV), Human Herpesvirus 6 (HHV-6), Candida albicans, Mycoplasma pneumoniae, Bordetella pertussis, Staphylococcus aureus, Candida glabrata, and Adenovirus.

Real-time Monitoring

The human RNase P gene is incorporated as a non-competitive internal control to monitor the entire nucleic acid extraction and amplification process, ensuring reliability and minimizing the risk of false-negative results.
