Direct Oral Swab 2x PCR Master Mix
Size 100 tests
Direct Oral Swab 2x PCR Master Mix allows you direct PCR without the tedious steps of any previous DNA extraction steps. Simply run your genotyping or pathogen detection assays directly from saliva or buccal swab samples.
Direct Oral Swab 2x PCR Master Mix contains HiDi Taq DNA polymerase and thus, is also proficient in all assays in which high single nucleotide discrimination is required, for instance in allele-specific amplifications (ASA) by PCR. HiDi Taq DNA polymerase efficiently amplifies from primers that are matched at the 3'-end and discriminates primers that are mismatched.
DNA isolation is not needed anymore - Direct Oral Swab 2x PCR Master Mix allows direct PCR, as well as PCR based genotyping or pathogen detection directly from saliva or buccal swab samples. The included DNA polymerase variant is engineered for superior PCR performance directly from saliva or buccal swab samples. Direct Oral Swab 2x PCR Master Mix contains HiDi Taq DNA polymerase and thus, is also proficient in all assays in which high single nucleotide discrimination is required, for instance in allele-specific amplifications (ASA) by PCR. HiDi Taq DNA polymerase efficiently amplifies from primers that are matched at the 3'-end and discriminates primers that are mismatched. The kit comes together with an optimized buffer system and a separate lysis buffer. The Direct Oral Swab 2x PCR Master Mix ensures reproducible results, significantly reduces set-up times and the risk of pipetting mistakes. It can also be used for real-time cycling when using fluorescence-based hydrolysis probes.
Direct Oral Swab 2x PCR Master Mix contains all components necessary for direct PCR or PCR based genotyping directly from saliva or buccal swab samples including an engineered DNA polymerase, an specifically optimized reaction buffer system, and ultrapure dNTPs. A hot-start formulation of the included DNA polymerase suppresses false amplification. Only target specific primers and samples need to be added.
Applications directly from saliva or buccal swab samples
- Direct PCR
- Genotyping & genomic profiling
- HLA genotyping
- SNP-detection by allele-specific amplification (ASA) / allele-specific PCR
- Pathogen detection
- End-point PCR
- Real-time PCR with fluorescence-based hydrolysis probes
All HiDi products are also compatible for real-time cycling, when adding a suitable real-time dye, for example GreenDye (#2000) or a fluorescent probe.
Direct Oral Swab 2xPCR Master Mix can also be used for hydrolysis-based probes (e.g. TaqMan) as the 5'-3' nuclease.
We recommend designing primers with a short amplicon length (about 60-200 bp) for best results, but also longer amplicon lengths are possible. The addition of additional magnesium chloride (+ 0.5 - 1.5 mM) might be needed in case of longer amplicons >500 bp.
Direct Oral Swab PCR Kit has been optimized for various sample collection kits and fresh saliva.
kits As amounts of stabilizing liquid vary between manufactures, it is recommended to dilute the collected sample with the provided lysis buffer to a final concentration of approximately 1-5 % saliva solution e.g. 2 µl sample (20 - 100 % saliva concentration) + 38 µl lysis buffer. As template 2.5 µl of this solution is then directly used for a 25 µl PCR reaction.
Fresh saliva should be collected in a reaction tube and centrifuged in a standard benchtop centrifuge for 20 sec at maximum speed. 2 µl of the supernatant should be mixed with 38 µl of the provided lysis buffer (5 % saliva concentration). After brief vortexing the reaction is cleared by centrifugation in a standard benchtop centrifuge for 60 sec at maximum speed. As template 2.5 µl of the supernatant is then directly used for a 25 µl PCR reaction yielding a final saliva concentration of 0.5 %. In the case of DNA collection with buccal swabs the sample should be placed in 200 µl of the provided lysis buffer. As template 2.5 µl of the saliva solution is then directly used for a 25 µl PCR reaction. Please note that the saliva solution of freshly collected samples without a sample collection kit can only be stored for up to 24 h at 4°C before use.
Quality Control Assays
PCR activity: Direct Oral Swab 2x PCR Master Mix was tested for successful allele-specific PCR performance detecting a genomic SNP (rs72921001) in genomic DNA from human saliva samples. PCR products were subsequently analysed on a 2.5% agarose gel.
DNA polymerase activity: DNA polymerase activity has been monitored and adjusted to a specific DNA polymerase activity using an artificial DNA template and a DNA primer. Enzyme-concentration has been determined by protein-specific staining. Please inquire more information at firstname.lastname@example.org for the lot-specific concentration. No contamination has been detected in standard test reactions.
