[CD6000] SMOChem™ dGTP Solution – Sodium Salt (100 mM), 25ml

Overview

• Collect from nasal, buccal, saliva, fecal, skin, surfaces, and more
• Completely stabilize microbiota profiles from the point-of-collection
• Minimize bias in data analysis: NGS (Metagenomics/Microbiome), PCR and microarrays
• No need to immediately process samples: ship and store at ambient temperatures
• DNA preservation at room temperature over 2 years
• Renders sample non-infectious for safe and easy shipping
• Compatible with DNA isolation kits and protocols: Optimized isolation procedure using Norgen’s Microbiome DNA Isolation Kit

Norgen’s Swab Collection and DNA Preservation System is designed for collection, ambient storage and transport of DNA from samples collected using a swab, including nasal, buccal, saliva, fecal, skin, surfaces, etc. The Swab Collection and DNA Preservation System contains Norgen’s Swab Preservative in a liquid format. The user simply collects the specimen using the provided swab, and then transfers the swab into the Swab Preservative. The Swab Preservative prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, the Swab Preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperatures. The components of the Swab Preservative allow DNA samples to be stored at room temperature for over 2 years.

DNA Isolation from Preservative

Swab samples collected and preserved using Norgen’s Swab Collection and DNA Preservation System are compatible with most DNA isolation methods. Samples stored in the tubes have been used successfully with most of Norgen Biotek’s DNA isolation kits and reagents. An optimized isolation procedure is available as part of Norgen’s Microbiome DNA Isolation Kit (Cat. 64100).

Description

The Cylindrospermopsin plate kit is a competitive enzyme-labeled immunoassay. The Cylindrospermopsin sample extract and calibrators are pipetted into the test wells followed by the Cylindrospermopsin antibody into the test wells to initiate the reaction. During the 30 minutes incubation period, Cylin-drospermopsin from the sample and Cylindrospermopsin antigen compete for binding to the Cylindrosper-mopsin antibody. The Cylindrospermopsin antibody is captured on the walls of the test well. Following this 30-minute incubation, the contents of the wells are removed and the wells are washed to remove any unbound Cylindrospermopsin and free Cylindrospermopsin antibody. After wash, 1X HRP-conjugated Antibody#2 is added for 30 minutes incubation. The wells are washed afterwards, and a clear substrate is then added to the wells and any bound enzyme conjugate causes the conversion to a blue color. Following a 15-minute incubation, the reaction is stopped and the amount of color in each well is read. The color of the unknown samples is compared to the color of the calibrators and the Cylindrospermopsin concentration of the samples is derived.

• HiDi® stands for High Discrimination of mismatches at the 3’-terminus of primers in PCR. This myPOLS Biotec enzyme family is optimized for this feature and therefor, is the first choice for applications that rely on this property such as allele-specific PCR (asPCR) that is also termed allele-specific amplification (ASA).HiDi® 2x PCR Master Mix – ready to use mix simplifies your PCR setup. Only target-specific primers and template need to be added as the mix contains all components for a successful and reliable PCR. This ensures reproducible results, significantly reduces set-up times and the risk of pipetting errors.This PCR mix is also available with a full-length Taq DNA polymerase with a nuclease domain, featuring 100% compatibility with hydrolysis probes (TaqMan® probes etc.).Benchmarking with products of competitors conducted by us and others show that the HiDi® DNA polymerase family is the first choice for highly selective PCRs, such as genotyping by allele-specific PCR, HLA genotyping, analysis of single CpG methylation sites or the detection of mutations in a high background of wild-type sequences. By using HiDi® DNA polymerase, less than 10 copies of a mutation can be detected in a background of >10.000 wild-type copies straight away without any other tedious assay optimization.It has also been shown that HiDi® DNA polymerase family is highly suitable for quality control in CRISPR-Cas or TALEN-based applications.Several independently conducted studies show that HiDi® DNA polymerase is ideally suited for use in asPCR in numerous research areas ranging from mutation detection to genome editing.

Example Primer Design

Matching vs. mismatching nucleotide is placed at the 3′-end of the primer for best discrimination results.

Example Results – There´s no accounting for taste

Cilantro: some people love it in their food, some hate it. Here we are detecting a genomic SNP (rs72921001) in HeLa genomic DNA. This SNP is reported to be close to a number of genes coding for olfactory receptors. (Reference: Eriksson N. et al. (2012), “A genetic variant near olfactory receptor genes influences cilantro preference.”)

Considering, that only the C-allele specific primer is extended and yielding in a specific amplicon, we can conclude a genetic predisposition in disliking cilantro, as this SNP is significantly associated with detecting a soapy taste to cilantro.  

Allele-specific PCRs were performed from 1 ng/µl of HeLa gDNA in the presence of a realtime dye, indicating the amplification of the C-allele specific primer only. The A-allele specific primer is discriminated, thus not amplified up to 50 cycles.

PCR products were subsequently analysed on a 2.5% agarose gel. Specific product is visualized by ethidium bromide staining at the amplicon length of 109 bp.
