Hard Facts .
- Easy self collecting
- High-quality DNA/RNA suited for all common downstream applications
- Best possible representation of the microbiome
- DNA and RNA stability up to 4 weeks
Applications .
Cq values for SARS-CoV-2 RT-qPCR targets N1, N2, and RP at day 0 (purple), day 7 (blue), and day 21 (orange) in low-positive (500 cp/ml, N = 15) and high-positive (2,500 cp/ml, N = 14) enriched saliva samples. The dotted line indicates the detection limit. If no amplification was detected, the cq was set to 45 (maximum cq) for visualization. Statistical significance was determined using a two-way ANOVA with Sidak’s test for multiple comparisons.

Outstanding stability .
DNA and RNA in the sample are stable for a long time at room temperature in OMR-110, OMR-120, OM-501 and OME-505 kits. This simplifies the transport chain and prevents microbiome profile distortion caused by microbial growth or nucleic acid degradation.

Realistic snapshot of the microbiome .
Samples obtained with OMNIgene kits are of excellent quality. The high integrity of the stabilized DNA allows a very realistic representation of the microbiome profile.

Quantifying the effects of pre-analytical factors: microbiome profile differences between technical replicates during sequencing, extraction, sample homogenization, of 3 different kits compared. Analysis was performed with respect to transport (temperature fluctuations between -8°C and +23°C, unstabilized and OMNIgenes) and donor to donor (control).
