- Highly sensitive and specific assay
- Low-cost alternative to other methods of Candida detection
- Compatible with most open qPCR platforms
- Smaller sample input that allows remaining extracted samples to be used in other tests
The AMPIPROBE Candida 2 Assay is a qualitative real-time PCR assay for the detection of C. parapsilosis and C. tropicalis genomic DNA. The nucleotide sequences of the PCR primers have been optimized to target sequences within species-specific regions of the Candida genome. The Candida primers have been designed using AMPIPROBE technology which incorporates reporter and quencher dyes into the primers. Target detection is based on fluorescence decay when successive rounds of amplification bring fluorophore and quencher-labeled primer pairs in close proximity resulting in FRET. Loss of fluorescence below a defined threshold in a particular channel indicates sample positivity for the corresponding Candida species.
The AMPIPROBE Candida 2 Primer Mix includes primers for a ubiquitously conserved human housekeeping gene (human β-globin). Successful amplification of the internal control serves as an indicator of sample adequacy, extraction efficiency and successful amplification in each individual sample.

Scientific Background: | Vulvovaginal candidiasis (VVC) is second, after bacterial vaginosis, among the many causes of vaginitis, and is diagnosed in up to 40% of women with vaginal complaints in the primary care setting. Approximately 70-75% of women will have at least one symptomatic Candida vulvovaginal infection during their lives. Accurate detection and differentiation of Candida species that cause VVC leads to a significant improvement in clinical management of women with vaginal complaints, especially in women with recurrent VVC (RVVC).
The current assay provides rapid and accurate results for the detection of C. albicans, C. glabrata, and C. krusei DNA in a user-supplied sample of interest. |
