Integrated DNA Technologies, Inc. (IDT), headquartered in Coralville, Iowa, is a supplier of custom nucleic acids, serving the areas of academic research, biotechnology, clinical diagnostics, and pharmaceutical development. IDT's primary business is the manufacturing of custom DNA and RNA oligonucleotides (oligos) for research applications.
When using a path length that is shorter than 10mm, the resultant OD will be reduced by a factor of 10/path length. Using the example above with a 3 mm path length, the OD for the 100 μg/mL sample would be reduced to 0.6. To normalize the concentration to a 10mm equivalent, the following is done: 0.6 OD X (10/3) * 50 μg/mL=100 μg/mL
Primer dimers may be visible after gel electrophoresis of the PCR product. PDs in ethidium bromide-stained gels are typically seen as a 30-50 base-pair (bp) band or smear of moderate to high intensity and distinguishable from the band of the target sequence, which is typically longer than 50 bp.
The RFU measurements are used, for DNA profiling, in a real-time polymerase chain reaction (PCR). Two common methods for detection of products in real-time PCR are: (1) non-specific fluorescent dyes that intercalate with any double-stranded DNA, and (2) sequence-specific DNA probes consisting of oligonucleotides that are labeled with a fluorescent reporter which permits detection only after ...
Droplet Digital PCR (ddPCR) is a method of dPCR in which a 20 microliter sample reaction including assay primers and either Taqman probes or an intercalating dye, is divided into ~20,000 nanoliter-sized oil droplets through a water-oil emulsion technique, thermocycled to endpoint in a 96-well PCR plate, and fluorescence amplitude read for all ...
In the first round of PCR, a KASP primer mix that contains the two allele-specific forward primers and the single reverse primer is added to the mixture. The specific nature of the forward primers allows for the primer to bind solely at the SNP of interest, allowing DNA polymerase to lay down the rest of the complementary nucleotides. During ...
Primer extension can be used to determine the start site of transcription (the end site cannot be determined by this method) by which its sequence is known. This technique requires a radiolabelled primer (usually 20 - 50 nucleotides in length) which is complementary to a region near the 3' end of the mRNA.
