The final PCR results for 11 samples analyzed with the QIAamp and UACH methods or ones examined with the QIAamp and CTAB methods were in agreement. Complete (100%) agreement was observed between data from the CTAB and UACH methods. CP values for the UACH and CTAB techniques were not significantly different, while the UACH method yielded significantly lower CP values compared to the QIAamp kit. The proposed extraction method combines reliability and efficiency with simplicity and lower cost. -

The best enrichment broth and DNA extraction scheme was determined for rapid and sensitive detection of Salmonella Enteritidis in steamed pork using real-time PCR. The inhibitory effect of commonly used Salmonella enrichment broths, Rappaport-Vassiliadis (RV) and Muller-Kauffmann tetrathionate with novobiocin (MKTTn), on real-time PCR was confirmed. The inhibition of PCR was statistically significant (p ＜ 0.05) in RV and MKTTn, as compared with buffered peptone water (BPW) or phosphate-buffered... -

한국식물병리학회 The Plant Pathology Journal 2010, 26권 3호 15 289-292 (4 pages)
the plant pathogenic fungus Cercospora sojina. Total DNA yield obtained by this method was approximately 1 mg/g of mycelia (fresh weight), and the mean ratio of A260/A280 and A260/A230 were 2.04 and 2.1, respectively. The results of random amplified polymorphic DNA (RAPD) analysis, digestion with restriction enzymes, and Southern hybridization indicated that polysaccharides were effectively removed by this method, and the resulting DNA was sufficient for use in subsequent molecular analysis. -
A Quick and Safe Method for Fungal DNA Extraction
한국식물병리학회 The Plant Pathology Journal 4 Pages
한국식물병리학회 The Plant Pathology Journal 2009, 25권 1호 17 108-111 (4 pages)
including cloning and genotyping, have become routine in fungal research laboratories. However, preparation of high-quality DNA from fungal tissue requires much time and labor and is often a limiting step for high-throughput experiments. We have developed a quick and safe (QS) DNA extraction method for fungi. Time efficiency and safety in the QS method were achieved by using plate-grown mycelia as the starting material, by eliminating phenol-chloroform extraction procedures, and by deploying a... -

(0 to 1,000 mg/kg) ranged from 68.34 to 95.49% (CV; 4.10 to 13.38%). DON in a buffer solution (250, 500 and 1,000 ng/mL) was isolated using 300 μg of NVRQS-DON and 3 mg of magnetic nanoparticles (MNPs). The mean recovery rates of DON using this mAb-MNP system were 75.2, 96.9, and 88.1% in a buffer solution spiked with DON (250, 500, and 1,000 ng/mL). Conclusively we developed competitive ELISAs for detecting DON in animal feed and created a new tool for DON extraction using mAb-coupled MNPs. -

Despite the potential importance of the human regulator of calcineurin 1 (RCAN-1) gene in the modulation of cell survival under stress, little is known about its role in death-inducing signal pathways. In this study, we addressed the effects of RCAN1.4 knockdown on cellular susceptibility to apoptosis and the activation of death pathway proteins. Transfection of siRNAs against RCAN1.4 resulted in enhanced Fas- and etoposide-induced apoptosis, which was associated with increased expression and... -

a loop-mediated isothermal amplification (LAMP) assay was developed to detect T. semipenetrans using DNA extracted from soil. A set of five primers was designed from the internal transcribed spacer region (ITS1) of rDNA, and was highly specific to T. semipenetrans. The LAMP reaction was performed at 63°C for 60 min. The LAMP product was visualized directly in one reaction tube by adding SYBR Green I. The detection limit of the LAMP assay was 10 J2/0.5 g of soil, which was 10 times more... -

산물인 216bp의 산물이 냉동감자가공품과 감자칩에서 검출되었으며 재조합유전자인 New leaf plus 유래의 증폭산물(234bp)와 New lear Y유래의 증폭산물(225bp)는 검출되지 않았다. 본 실험의 결과 시료의 가공특성과 적용한 추출 kit 및 방법에 따라 genomic DNA 순도 및 추출수율이 크게 차이가 났으며 이것이 결국 PCR 결과에 의음성 혹은 의양성 등에 영향을 미치게 될 것으로 판단된다. 또한, 동일한 DNA추출방법에 의해서도 DNA가 추출되지 않은 경우가 있어서 동일한 시료에서 2회 반복 추출하는 것이 의음성결과를 피할 수 있는... -

의래 추출된 DNA를 대상으로 계통학적 군집해석을 수행한 결과가 보다 더 다양한 계통군을 검출할 수 있음이 밝혀졌다. 한편, ISOIL kit를 이용하여 구축된 총clone중 약40%가${alpha}-proteobacteria$ 계통군에 속하였으며, 약 30%가 ${gamma}-Proteobacteria$ 계통군에 속하여 우점 계통군으로 확인된 반면, manual법에 의해 구축된 clone의 41%가 Acidobacteria 계통군에 속하였고 ${alpha}-proteobacteria$(28%)가 우점 계통군으로 분포하는 계통학적 특징을 나타내어 DNA추출법에 따라 토양 세균군집 구조의 계통학적 특성 이...
