What is the maximum size of insertion/deletion that can be detected by a TaqMan SNP Genotyping Assay?
Assays can detect an insertion/deletion of up to 6 bases. If you desire an assay to detect a larger insertion or deletion you may want to consider our Custom Design Service (https://www.thermofisher.com/us/en/home/life-science/pcr/real-time-pcr/custom-services-reagents-real-time-pcr-qpcr/custom-services-real-time-pcr-assays.html).
What can I do if there are no predesigned assays to my SNP?
You can use our Custom Assay Design Tool (https://www.thermofisher.com/us/en/home/life-science/pcr/real-time-pcr/real-time-pcr-assays/snp-genotyping-taqman-assays/custom-snp-assays.html?ICID=ta-lm-custom%20taqman%20snp%20assay-Single%20Tube%20Custom%20TaqMan%C2%AE%20SNP%20Genotyping%20Assays) to submit your SNP sequence for an assay design. Alternatively, you can also use Primer Express Software to design an assay.
How do I find an assay to my SNP?
You can easily find predesigned TaqMan SNP Genotyping Assays with our user-friendly search tool at https://www.thermofisher.com/us/en/home/life-science/pcr/real-time-pcr/real-time-pcr-assays/snp-genotyping-taqman-assays.html. Simply search by:
-Target (assay ID, rs number, gene symbol)
-Specific location on a chromosome
You can also watch this short video (https://www.youtube.com/watch?feature=player_embedded&v=qA4VWe8Jyrs) on how to search for assays.
Can the TaqMan SNP Genotyping Assays be used for allele quantification?
No. TaqMan SNP assays contain competitive probe sequences with a 1 bp mismatch where the SNP is located. The other probe will still bind at a lower efficiency, producing some signal for the other fluorophore. Therefore, these are not quantitative.
In my TaqMan SNP Genotyping Assay, which base is labeled with FAM or VIC dye?
The probe labels are provided in the assay documentation and also online. Simply look up the assay by typing the assay ID into the search bar on thermofisher.com. Click on the View Details button, and under the Product Details look for the Context Sequence. The assays are always in a [VIC/FAM dye] order. From the context sequence, you can see which base is first (thus labeled with VIC dye), and which is second (thus labeled with FAM dye).
Determination, mechanism and monitoring of knockdown resistance in permethrin-resistant human head lice, Pediculus humanus capitis
Authors:Clark, JM
Journal:JOURNAL OF ASIA-PACIFIC ENTOMOLOGY
PubMed ID:
Permethrin resistance has been reported worldwide and clinical failures to commercial pediculicides containing permethrin have likewise occurred. Permethrin resistance in head lice populations from the U.S. is widespread but is not yet uniform and the level of resistance is relatively low (∼4-8 fold). Permethrin-resistant lice are cross-resistant to pyrethrins, PBO-synergized ... More
Geographical mapping of a multifocal thyroid tumour using genetic alteration analysis & miRNA profiling
Background: Papillary thyroid carcinoma (PTC) frequently presents as multiple tumour-foci within a single thyroid gland or pluriform, with synchronous tumours comprising different histological variants, raising questions regarding its clonality. Among the genetic aberrations described in PTC, the BRAF V600E mutation and ret/PTC activation occur most commonly. Several studies have investigated ... More
Risk haplotype analysis for bovine paratuberculosis
Paratuberculosis (Johne's disease), caused by Mycobacterium avium subsp. paratuberculosis, is an important disease for bovines, although its genetic basis is poorly understood. In this study, three candidate genes were typed to study the associations between single nucleotide polymorphisms (SNPs) and paratuberculosis susceptibility (measured in a 1 or 0 form) at ... More

Association of Polymorphisms in Genes of the Homologous Recombination DNA Repair Pathway and Thyroid Cancer Risk
Background: Ionizing radiation exposure has been pointed out as a risk factor for thyroid cancer. The double-strand breaks induced by this carcinogen are usually repaired by homologous recombination repair pathway, a pathway that includes several polymorphic genes. Since there is a scarcity of data about the involvement of these gene ... More
