background: fetal dna in maternal plasma and serum has been shown to be a useful material for prenatal fetal sex determination during early gestational ages. non-invasive prenatal diagnosis is now possible at 8th week of pregnancy, by maternal blood sample testing. objective: the purpose of this study was to evaluate two dna extraction methods from mother plasma and its routine clinical applica...

Progress in DNA-encoded chemical library synthesis and screening crucially relies on the availability of DNA-compatible reactions, which proceed with high yields excellent purity for a large number possible building blocks. In past, experimental conditions have been presented execution Suzuki Sonogashira cross-coupling reactions on-DNA. this article, our aim was to optimize comparing results pr...

The demand for molecular analysis of aquatic microbial communities in freshwater has highlighted the need for efficient methods of DNA extraction. The centrifugation method and filtration-membrane method are 2 widely used methods for extracting DNA. The objective of this study was to compare the extraction efficiency of 3 methods, including the centrifugation method, filtration-membrane method,...

An efficient DNA isolation protocol specifically modified to get pure quality DNA required for molecular studieshas been reported in this paper. Some aquatic plants (Potamogeton spp., Ceratophyllum demersum and Myriophyllum spicatum) were used for the study. The protocol developed will be useful in getting high and pure DNA. Instead of using the available DNA extraction kits, this protocol can ...

The generation of single-stranded DNA (ssDNA) molecules plays a key role in the SELEX (Systematic Evolution of Ligands by EXponential enrichment) combinatorial chemistry process and numerous molecular biology techniques and applications, such as DNA sequencing, single-nucleotide polymorphism (SNP) analysis, DNA chips, DNA single-strand conformation polymorphism (SSCP) analysis and many other te...

Introduction: Auger electron based radioimmunotherapy (RIT) using 111In-DOTA-trastuzumab (111In-DOTA-antiHer2) feasibility was studied in vitro on a HER2/neu positive cell line, SkBr3. Methods:111In-DOTA-antiHer2 was prepared according to the optimized conditions followed by quality control tests including radioch...

is required for many molecular biology applications. Accurate PCR replication of RNA and DNA sequences requires complete removal of cellular lipids and proteins. Likewise, most restriction endonucleases used to digest genomic DNA are inactivated or degraded by cellular proteases normally present prior to purification of the nucleic acids. Thus, failure to remove these cellular contaminants ofte...

Molecular marker techniques have been widely used for cultivar identification of inbred date palms (Phoenix dactylifera L.; Arecaceae) and biodiversity conservation. Isolation of highly pure DNA is the prerequisite for PCR amplification and subsequent use such as DNA fingerprinting and sequencing of genes that have recently been developed for barcoding. To avoid problems related to the preserva...

Objective and Material and Methods This study aimed to compare the quantity and quality of human DNA extracted from saliva that was fresh or frozen for three, six and twelve months using five different DNA extraction protocols: protocol 1 - Oragene™ commercial kit, protocol 2 - QIAamp DNA mini kit, protocol 3 - DNA extraction using ammonium acetate, protocol 4 - Instagene™ Matrix and protocol 5...

bandstab. If the desired level of purity had not been achieved from the first round of bandstab, it was possible to reamplify the target fragment from the gel used to check the yield and purity of the initial bandstab products. The bandstab approach can bypass the need for cloning PCR products and all associated work required to generate recombinants, check the insert size and prepare recombina...
