A fast, simple, and reliable mini-prep method for the extraction of DNA from Gossypium species and cultivars has been developed. This small-scale method is cetyltrimethylammonium bromide (cTAB)-based, and it extracts DNA from one to three folded or nearly unfolded young leaves processed in a 1.5 mL tube with 0.5 mL of extraction buffer and homogenized by an electric drill. Compared with the mac...

Formation and electronic excitation energy transfer process in the nanosystem consisting of Ce0.85Tb0.15F3 nanoparticles, cetrimonium bromide (CTAB) surfactant, and chlorin e6 photosensitizer were studied. It was shown that chlorin e6 molecules bind to Ce0.85Tb0.15F3 NP in the presence of CTAB forming thus Ce0.85Tb0.15F3 NP-CTAB-chlorin e6 nanosystem. We consider that binding occurs via chlorin...

Deoxyribonucleic acid (DNA) extraction in abaca (Musa textilis Née), the source of strongest natural fiber (Manila hemp), is difficult due to its fibrous nature, high cellulose content, and polyphenol compounds. Thus an optimized DNA method required for extracting quality next-generation sequencing applications. This study, hence, aimed test compare five different methods molecular weight from ...

fasciolosis is an important parasitic disease common among humans and livestock. it is considered as a health problem and causes great economic losses in several regions of the world. considering the prevalence of fascioliasis, study on molecular aspect of the parasite is so much important. the present study was carried out to achieve a suitable method of dna extraction from fasciola for furthe...

The isolation of intact, high-molecular mass genomic DNA is essential for many molecular biology applications including PCR, endonuclease digestion, southern blot analysis, and genomic library construction. Many protocols are available for the extraction of genomic DNA from plant tissue, and all the protocols have used expensive and hazardous chemical-liquid nitrogen for grinding plant material...

Isolation of nucleic acids from Chlorella is difficult, given the chemically complex nature of their cell walls and variable production of metabolites. Immobilization of microalgae in polymers adds additional difficulty. Here, we modified, amended, and standardized methods for isolation of nucleic acids and compared the yield of DNA and RNA from free-living and encapsulated microalgae C. soroki...

Nigella sativa L. (Ranunculaceae) seeds (black cumin) that contain high oil, terpene, protein, alkaloids are an economically important for medicine and food industry. Lack of an efficient DNA isolation procedure is a limiting factor for any molecular studies of these plant. We have used a genomic DNA isolation protocol for Nigella sativa seeds based on a hexadecyltrimethylammonium bromide (CTAB...

Tri-block copolymers (poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide), represented as EOxPOyEOx), pluronics (F127 = EO106PO70EO106, P65 = EO20PO30EO20, P85 = EO27PO39EO27, P103 = EO17PO55EO17, and P123 = EO20PO70EO20) and cationic surfactants (cethyltrimethylammonium bromide (CTAB)), two surfactant systems, form complex micelles that self-assemble into mesostructured particles w...

The interaction between the cationic surfactant Hexadecyltrimethylammonium bromide (CTAB) and the ionic liquid 1-butyl-3-methylimidazolium octyl sulfate (bmim-octylSO4) in aqueous solution has been investigated at two total concentrations (0.5 and 10 mM) and different CTAB mole fractions (CTAB). Samples of different physical appearance were obtained depending on CTAB suggesting different kind...

in this work, a new, simple and fast method for the solid phase extraction-spectrophotometric determination of phosphate using cetyltrimethyl ammonium bromide immobilized on alumina-coated magnetite nanoparticles (ctab@acmnps) has been developed. the determination of phosphate is based on the molybdenum blue method which was monitored at λmax of 810 nm. mnps and acmnps characterized by sem, vsm...
