Orcinol reaction with rna
WebApr 24, 2015 · Aim: To estimate the concentration of RNA by orcinol reaction. Principle: This is a general reaction for pentoses and depends on the formation of furfural when the. pentose is heated with concentrated hydrochloric acid. Orcinol reacts with the furfural in the. presence of ferric chloride as a catalyst to give a green colour, which can be ... Webaddition of the modified orcinol reagent does not decrease the absorbance due to RNA and abolished the absorbance due to DNA. Incubation at 37°C might be equally effective.

Standard RNA … WebBial's test is a chemical test for the presence of pentoses originally developed for the diagnosis of Pentosuria.It is named after Manfred Bial, a German physician.The components include orcinol, hydrochloric acid, and ferric chloride.A pentose, if present, will be dehydrated to form furfural which then reacts with the orcinol to generate a colored substance.
WebThe color reaction of orcinol reagent for DNA* has been investigated. DNA re acted with the orcinol reagent much faster than RNA, and a color with an absorption maximum at 600mƒÊ was developed within a few minutes. The color intensity at 600 my became the maximum in 2 min after the reaction.
