چکیده

isolation of cell free fetal dna (cffdna) from maternal serum usually leads to very low concentrations of dna impeding further resolving through conventional methods of electrophoresis. although several protocols have been described for capillary electrophoresis (ce) of double stranded dna, they usually need using special polymers or coated capillaries which degrade over time. herein, we proposed a new and very simple protocol using uncoated fused silica capillary for ce of cffdna purified from serum of pregnant women. the proposed protocol was able to determine the presence of small fetal dna fragments and it also confirmed the optimization of sonication performed on purified cffdna samples.

Capillary electrophoresis of double-stranded DNA fragments using a new fluorescence intercalating dye EvaGreen.

EvaGreen is a new DNA intercalating dye successfully used in quantitative real-time PCR. In the present work, we firstly apply EvaGreen to the analysis of dsDNA by CE with LIF detection. Comparisons of EvaGreen dye with the commonly used dyes SYBR Green I and SYBR Gold were preformed in dsDNA analysis by CE. The linear range of dsDNA using EvaGreen was slightly wider than that using SYBR Gold a...

A simple and efficient DNA extraction protocol for old herbarium leaves of Bellevalia (Asparagaceae, Scilloideae)

High-quality DNA extraction plays an important role to make sharp bands in the gel electrophoresis and also produces clean chromatograms. Usually, DNA extract is delivered using the modified CTAB method but this method cannot obtain high-quality DNA for molecular analysis from old dried leaves of Bellevalia due to having different chemical compounds which inhibit to obtain a clear DNA extractio...

A stability indicating capillary electrophoresis method for analysis of buserelin

A simple and rapid stability indicating method based on capillary zone electrophoresis has been developed and validated for the analysis of buserelin (BUS). The best separations were achieved by using a bare fused silica capillary (75 m i.d.; 65.5 cm total, 57.0 cm effective length), phosphate buffer (pH = 3.00; 26.4 mM), at 35 °C. The sample was hydrodynamically injected at 50 mbar for 5 seco...

Cell‐free fetal DNA: the new tool in fetal medicine

Since the discovery of cell-free fetal DNA (cffDNA) in maternal plasma in 19971 there has been rapid progress in harnessing this as a source of fetal genetic material for prenatal diagnosis. The majority of cell-free DNA (cfDNA) is maternal in origin2, with the fetal proportion emanating from the placenta3, detectable in the maternal circulation from around 5 weeks’ gestation2 and constituting ...
