We recommend using Norgen's RNA purification kits for RNA isolation from all specimen types.

Norgen can accept purified RNA extracted by any commercial method, however we highly recommend avoiding the use of any phenol:chloroform-based RNA extraction. Please consult one of our scientists for the best approach for RNA extraction for your sample.

> (cell-free samples and exosomes) Required RNA and minimum concentration: 15 μL of 50pg/μL
> (cellular samples and whole blood) - Required RNA volume and minimum concentration: 15 μL of 10ng/μL
