We compared and statistically evaluated the effectiveness of nine DNA extraction procedures by using frozen and dried samples of two silt loam soils and a silt loam wetland sediment with different organic matter contents. The effects of different chemical extractants (sodium dodecyl sulfate [SDS], chloroform, phenol, Chelex 100, and guanadinium isothiocyanate), different physical disruption met...

OBJECTIVE Polymorphisms in intron 1 of the 'fat mass and obesity-associated' (FTO) gene are associated with weight status. We hypothesized that the risk allele at a polymorphism in intron 1 of FTO is associated with weight regain after end of lifestyle intervention. METHODS We longitudinally analyzed the changes of weight status as BMI-SDS in 346 unrelated overweight children (mean age 10.6 ±...

Aeromonas hydrophila isolated from fish (Labeo rohita), pond water, river water, raw meat of chicken and mutton and raw cow milk were characterized through Random Amplified Polymorphic DNA (RAPD) analysis and Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS PAGE) of cellular proteins. RAPD-PCR amplification of bacterial DNA was done by using ten random primers (OPA-01 to 10) and ...

Extraction of DNA from Schizosaccharomyces pombe cells is required for various uses, including templating polymerase chain reactions (PCRs), Southern blotting, library construction, and high-throughput sequencing. To purify high-quality DNA, the cell wall is removed by digestion with Zymolyase or Lyticase and the resulting spheroplasts lysed using sodium dodecyl sulfate (SDS). Cell debris, SDS,...

Antimicrobial activity of certain species Lactobacillus bacteria were known to produce a type bacteriocin called Plantaricin (Pln). In this study, the PlnF (plnF) gene (666 bp) encoding plantaricin was synthetically constructed based on sequence predefined and valuable amino acid compositions subcloned into pET-28 (+) expression vector. Thereafter transformation recombinant vector BL21 (DE3) co...

RNA integrity is critical for successful RNA quantitation for mammalian tissues, but the level of integrity required differs among tissues. The level of integrity required for quantitation has not been determined for bacterial RNA. Three RNA isolation methods were evaluated for their ability to produce high quality RNA from Dickeya dadantii, a bacterium refractory to RNA isolation. Bacterial ly...

The study aims to produce Expansin protein isolated from a young tomato plant by using Escherichia coli which is used in recombinant production. Continuous culture the most common method grow cells for In study, K12 strain of E. was as production protein. LeExp1 gene plant. Since related found very small amounts plants, it has been reproduced PCR and made workable with this method. T17 vector (...
