WebIn the widely used guanidinium thiocyanate phenol-chloroform method, the cell extract is extracted with phenol/chloroform at low pH. Guanidinium thiocyanate is a chaotropic agent used in protein degradation. The principle of this single-step technique is that RNA is separated from DNA after extraction with acidic solution consisting guanidinium … Webtraction increases the sensitivity of the thiocyanate method, but little information is available on the iron(III) species in the organic phase.4,5 The present investigation is an attempt to study the stoichiometry of the extracted iron thiocyanate complex in chloroform with cetyltrimethylammonium (CTMA) bromide and tetraphenylphosphonium (TPP ...
Webthiocyanate method The ferric thiocyanate method was used to evaluate the effect of silymarin and reference antioxidants on preventing peroxidation of linoleic acid described previously [22,23].

Acid guanidinium thiocyanate-phenol-chloroform extraction (abbreviated AGPC) is a liquid–liquid extraction technique in biochemistry. It is widely used in molecular biology for isolating RNA (as well as DNA and protein in some cases). This method may take longer than a column-based system such as the silica-based purification, but has ...
Thiocyanate shares its negative charge approximately equally between sulfur and nitrogen. As a consequence, thiocyanate can act as a nucleophile at either sulfur or nitrogen — it is an ambidentate ligand. [SCN] can also bridge two (M−SCN−M) or even three metals (>SCN− or −SCN<). Experimental evidence leads to the general conclusion that class A metals (hard acids) tend to form N …
WebBrief Method Summary. Thiocyanate ion is liberated from mercuric thiocyanate by the formation of soluble mercuric chloride. In the presence of ferric ion, free thiocyanate ion forms a highly colored ferric thiocyanate, of which the intensity is proportional to the chloride concentration.
