Differences are also encountered when collecting the sample; ThinPrep requires the collector to rinse the collection device in the liquid media that is followed by disposal of the collection device.
Our study has demonstrated that oral rinse sample collection is an unobtrusive method to use for detection of oral HPVs.
In October and November of 2010, one round of hand rinse data collection was conducted during designated break times.
In our study, we used oral rinse sample collection coupled with real-time PCR to detect for HPVs types 16 and 18, and preferentially amplified FAP PCR samples to detect for a broad range of HPVs, in oropharyngeal squamous cell carcinoma (OPSCC), non-OPSCC, and healthy patients.
To evaluate reproducibility of oral rinse self-collection for human papillomavirus (HPV) detection and investigate associations between oral HPV, oral lesions, immune and sociodemographic factors, we performed a cross-sectional study of older adults with human immunodeficiency virus (HIV) infection.
For the point of entry to the home, the home visitor ran the water for 15 minutes, rinsed the collection bottle three times, obtained a 50 ml sample in a polypropylene bottle and sealed the cap.
The collected SPE fraction was evaporated to 200 μl with a stream of nitrogen at 40°C and transferred to a GC autosampler vial while rinsing the collection tube with an additional volume of 200 μl of toluene.
Discard supernatant and resuspend pellet in 200 μl PBS I. Prior to buccal cell collection rinse mouth twice thoroughly with 100 ml of water.
The cells were incubated with antibodies against CD45-APC (1 100), CD11b-PE/Cy7 (1:100), NK1.1-APC/Cy7 (1:20), Ly-6G/Ly-6C (Gr1)-PacificBlue (1:50), Cd45R/B220-PerCP/Cy5.5 (1 100), and CD3-Alexa Flour 700 (1 100) (BioLegend) for 30 min. After collection, rinsing with RPMI 1640 and filtration through a nylon screen (40 μm), the cells were sorted and analyzed on a FACSAria system (BD Bioscience).
In extended exposure protocols, following an initial buccal cell collection (rinsing with dH2O (Day 1-Wash 1 (D1-W1) and Day 1-Wash 2 (D1-W2))), participants waited 6 days for epithelium recovery and then began an exposure protocol of two H2O2 mouthwash washes/day for 2 min.
