STR Profiling - Eppendorf Handling Solutions
STR profiling can be performed in-house or by a service provider. In-house testing is only recommended if STR profiling is routinely needed and performed according to the consensus standard (ANSI/ATCC ASN-0002-2011). This technique requires a capillary electrophoresis system, which can represent a high financial investment for laboratories. ... Read Here

Sequencing Long Amplicon Microsatellite Loci Using the Oxford Nanopore Technologies MinION Device. Purpose: Forensic DNA typing exploits the high variability of short tandem repeat (STR) markers to differentiate individuals. Typical STR workflow consists of PCR followed by separation and detection via capillary electrophoresis (CE). ... Read Document

Analysis Of Short Tandem Repeats By Parallel DNA Threading
As was shown in this 3-plex amplification, the length variation between threads of different STRs allows the shorter threads to be amplified at the expense of the longer ones in the PCR step. However, the longest threads, corresponding to the D18S51 marker, were still easily detectable with capillary gel electrophoresis. ... Visit Document

Sensitivity, Reproducibility, And Accuracy In Short Tandem ...
Capillary array electrophoresis (CAE) offers rapid, high-resolution separations, high throughput, and sensitive detection. To assess the utility of CAE for the accumulation of genetic information, we tested both sizing accuracy and reproducibility using 48-capillary prototype systems. ... Access Document

Figure 1 – Sample separation using the QIAxcel Advanced System. Nucleic acid molecules are size-separated by applying an electrical current to a gel-filled capillary. A detector in the instrument detects the nucleic acid molecules as they migrate toward the positively charged terminus of the capillary. ... Fetch This Document

STR Analysis - Wikipedia
There are two common methods of separation and detection, capillary electrophoresis (CE) and gel electrophoresis. Each STR is polymorphic, but the number of alleles is very small. Typically each STR allele will be shared by around 5 - 20% of individuals. The power of STR analysis comes from looking at multiple STR loci simultaneously. ... Read Article

STR Data Analysis & Interpretation For Forensic Analysts
Data produced in the separation and characterization of amplified DNA is displayed as: • Peaks (capillary electrophoresis) • Bands (slab gel electrophoresis) The DNA fragments are sized, which includes an indirect assessment of quantity present (peak area/height or band density), and genotypes are assigned. ...

Zoe Bianchi: The Use Of Electrophoresis In Forensic Science
Capillary electrophoresis (figure 2), in which a fused silica capillary is used instead of a gel slab, is now being used more frequently in DNA electrophoresis. Although applying the same principles of separation as the more traditional gel slab electrophoresis, it is more rapid and has a higher resolution. ... Read Content

Capillary Gel Electrophoresis - An Overview | ScienceDirect ...
Capillary Gel Electrophoresis. Capillary gel electrophoresis is used for the separation of macromolecules such as proteins and nucleic acids, whose mass-to-charge ratios do not vary much with size. Separation requires a sieving medium made up of a crosslinked gel or an entangled polymer network. ... Access Full Source

DNA - Analysis Part 1 - Introduction To Forensic Science
This is achieved by separation using capillary electrophoresis. Key points of this method are that dyes are used to label the amplicons, separation of amplicons is by size, and there is a built in sizing reference standard. STRs with alleles that are in a similar size range are differentiated by the colour of the dye. ... Fetch Content

Utilizing Short Tandem Repeats (STRs) As A Resolving Matrix ...
By using capillary or gel electrophoresis the STRs were fluorescently labeled during the PCR. This was possible since either the forward or reverse locus-specific primer contains a fluorescent dye. To determine the size of each STR allele, we recorded the dye colour and migration time of each DNA fragments in relation to an internal standard. ... Document Retrieval
