Dna Extraction Method

BACKGROUND Dried blood spot (DBS) samples have been widely used in newborn screening (NBS) for the early identification of disease to facilitate the presymptomatic treatment of congenital diseases in newborns. As molecular genetics knowledge and technology progresses, there is an increased demand on NBS programs for molecular testing and a need to establish reliable, low-cost methods to perform those analyses. Here we report a flexible, cost-efficient, high-throughput DNA extraction method from DBS adaptable to small- and large-scale screening settings. METHODS Genomic DNA (g.DNA) was extracted from single 3-mm diameter DBS by the sequential use of red cell lysis, detergent-alkaline, and acid-neutralizing buffers routinely used in whole blood and plant tissue DNA extractions. We performed PCR amplification of several genomic regions using standard PCR conditions and detection methods (agarose gel, melting-curve analysis, TaqMan-based assays). Amplicons were confirmed by BigDye® Terminator cycle sequencing and compared with reference sequences. RESULTS High-quality g.DNA was extracted from hundreds of DBS, as proven by mutation detection of several human genes on multiple platforms. Manual and automated extraction protocols were validated. Quantification of g.DNA by Oligreen® fluorescent nucleic acid stain demonstrated a normal population distribution closely corresponding with white blood cell counts detected in newborn populations. CONCLUSIONS High-quality, amplifiable g.DNA is extractable from DBSs. Our method is adaptable, reliable, and scalable to low- and high-throughput NBS at low cost ($0.10/sample). This method is routinely used for molecular testing in the New York State NBS program.

Abstract Background The use of sequencing and genotyping platforms has undergone dramatic improvements, enabling the generation of a wealth of genomic information. Despite this progress, the availability of high-quality genomic DNA (gDNA) in sufficient concentrations is often a main limitation, especially for third-generation sequencing platforms. A variety of DNA extraction methods and commercial kits are available. However, many of these are costly and frequently give either low yield or low-quality DNA, inappropriate for next generation sequencing (NGS) platforms. Here, we describe a fast and inexpensive DNA extraction method (SILEX) applicable to a wide range of plant species and tissues. Results SILEX is a high-throughput DNA extraction protocol, based on the standard CTAB method with a DNA silica matrix recovery, which allows obtaining NGS-quality high molecular weight genomic plant DNA free of inhibitory compounds. SILEX was compared with a standard CTAB extraction protocol and a common commercial extraction kit in a variety of species, including recalcitrant ones, from different families. In comparison with the other methods, SILEX yielded DNA in higher concentrations and of higher quality. Manual extraction of 48 samples can be done in 96 min by one person at a cost of 0.12 €/sample of reagents and consumables. Hundreds of tomato gDNA samples obtained with either SILEX or the commercial kit were successfully genotyped with Single Primer Enrichment Technology (SPET) with the Illumina HiSeq 2500 platform. Furthermore, DNA extracted from Solanum elaeagnifolium using this protocol was assessed by Pulsed-field gel electrophoresis (PFGE), obtaining a suitable size ranges for most sequencing platforms that required high-molecular-weight DNA such as Nanopore or PacBio. Conclusions A high-throughput, fast and inexpensive DNA extraction protocol was developed and validated for a wide variety of plants and tissues. SILEX offers an easy, scalable, efficient and inexpensive way to extract DNA for various next-generation sequencing applications including SPET and Nanopore among others.

Dna Extraction Method

AbstractBackgroundConsistent isolation of high quality plant genomic DNA is a prerequisite for successful PCR analysis. Time consumption, ease of operation and procedure cost are important secondary considerations for selecting an effective DNA extraction method. The simple, reliable and rapid DNA extraction method developed by Edwards and colleagues in 1991 [1] has proven to be the gold standard.ResultsThrough modification of the Edwards method of extraction, we have developed a one-tube protocol that greatly improves the efficiency of plant DNA extraction and reduces the potential for sample contamination while simultaneously yielding high quality DNA suitable for PCR analysis. We further show that DNA extracts prepared with this method are stable at room temperature for at least three months.ConclusionThe one-tube extraction method yields high quality plant DNA with improved efficiency while greatly minimizing the potential for cross contamination. This low-cost and environment-friendly method is widely applicable for plant molecular biology research.

ABSTRACT: In this study, a non-destructive, high-throughput, endosperm-based DNA extraction method was developed. To verify the non-destructive nature of this method, a germination test was performed on 288 seeds after sampling their endosperm, which gave a seedling emergence rate that was higher (97.6%) than that of the control group (92%). To confirm the feasibility of the new method, DNA was extracted from plants of a BC1F2 population by two different methods, namely, from endosperm using our rapid, high-throughput method (ER-DNA) and from young leaves emerging from the same sampled seed using the CTAB method (LC-DNA). The ER-DNA was undetectable by agarose gel electrophoresis, but was found to be an adequate replacement for LC-DNA for the amplification and detection of simple sequence repeats (SSRs). Further analysis revealed that ER-DNA was generally suitable for the generation of specific 500-750-bp fragments, but not for the amplification of 1,000-2,000-bp fragments. Our rapid, high-throughput method therefore has no deleterious effects on wheat seeds and yields DNA for SSR genotyping that is a suitable alternative to traditionally obtained DNA.

<p style="text-align: justify;"><strong>Aim</strong>: To compare different methods for extracting DNA from non-recalcitrant and recalcitrant tissues of <em>Vitis vinifera</em> woody plants and propose a modification of a previously published method to reduce the time and cost of extraction.</p><p style="text-align: justify;"><strong>Methods and results</strong>: DNA was extracted from young and mature leaves as well as from stems and seeds using some of the most common methods of DNA isolation and two commercial kits. Another commercial kit, which does not require DNA extraction prior to PCR, was also used. Only two methods provided adequate results in all tissues. Other methods were only applicable to some tissues and some did not yield any functional DNA in any tissue. A modification of the method reported by Marsal <em>et al</em>. (2011) is proposed to reduce handling time and cost.</p><p style="text-align: justify;"><strong>Conclusion</strong>: All of the methods studied here use a surfactant to improve the extractions. For DNA extraction from recalcitrant tissues to be optimal, it is best to use a combination of dodecyltrimethylammonium bromide (DTAB) and cetyltrimethylammonium bromide (CTAB). The changes made to the protocol reported by Marsal <em>et al</em>. (2011) enable functional DNA to be obtained from leaves in only 90 minutes and at very low cost (17 €/8 samples). However, this method cannot adequately isolate DNA from recalcitrant tissues (stems and seeds) and so, for this type of sample, we would recommend using the original method.</p><p style="text-align: justify;"><strong>Significance and impact of the study</strong>: Nowadays, handling time and cost are key factors in selecting the most suitable DNA extraction method. This study compares not only the effectiveness of the various methods but also the handling time and cost. It also proposes a modification of the fastest and most economic DNA extraction method for leaves so that handling time and processing cost will be reduced even further.</p>
