Norgen’s EXTRAClean Urine Cell-Free Circulating RNA Purification Kits provide a fast, reliable, reproducible, and simple procedure for isolating circulating RNA and exosomal RNA from various urine inputs ranging from 250 μL and up to 30 mL. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real-time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extensions, and expression array assays.
EXTRAClean Cell-Free Circulating RNA Purification Mini Kit: For sample volumes ranging from 250 μL to 2 mL
EXTRAClean Cell-Free Circulating RNA Purification Midi Kit: For sample volumes ranging from 2mL to 10mL. The first column will handle the large volume input of urine that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL
EXTRAClean Cell-Free Circulating RNA Purification Maxi Kit: For sample volumes ranging from 10 mL to 30 mL. The first column will handle the large volume input of urine that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL.
