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.

Genotype directly from RNA samples. RNA reverse transcription and cDNA PCR genotyping simultaneously in a single, one-step reaction.
ProbeSure OneStep RT-PCR Master Mix combines reverse transcription (RT) and PCR in a single step. This advanced master mix simplifies workflows by eliminating the need for separate reactions for reverse transcription of RNA to cDNA, and PCR amplification from the newly generated cDNA.
ProbeSure OneStep RT-PCR Master Mix is highly efficient and sensitive, enabling detection of low-abundance RNA targets, particularly useful for applications such as gene expression analysis and viral RNA detection. ProbeSure OneStep RT-PCR Master Mix demonstrates robust performance across a wide range of RNA templates and can be employed for both routine and challenging samples.
