Method for assigning double-stranded RNA structures

A rapid method for isolation of double stranded RNA.

A rapid and simple method for the isolation and purification of dsRNA is presented. The crucial step of this method is the extraction of proteins and DNA with acid phenol. After the extraction, only RNA is left in the aqueous phase. ssRNA contamination of the RNA preparation can be greatly reduced when ammonium sulfate is present during the extraction.

Interaction of sanguinarine with double stranded RNA structures.

Interaction of sanguinarine with A-form RNA structures of poly(rI)poly(rC) and poly(rA).poly(rU) has been studied by spectrophotometric, spectrofluorimetric, UV melting profiles, circular dichroism and viscometric analysis. The binding of sanguinarine to A-form duplex RNA structures is characterised by the typical bathochromic and hypochromic effects in the absorption spectrum, increasing stead...

double-stranded rna viral infection in tehran trichomonas vaginalis isolates.

background : trichomonas vaginalis is a pathogenic protozoon and may be contaminated with dsrna virus called trichomonas vaginalis virus (tvv). the viral infection is an important factor for its patho-genesis and sensitivity to metronidazole. the presence of tvv is associated with qualitative and quantitative expression of cysteine proteinases and surface immunogenic; p270. the purpose of this ...
