  • Quick & Easy: Simple spin-column based isolation from up to 3 mL of plasma, serum, or other biological liquids. No phenol/chloroform or precipitation.
  • Highest Yields: Efficient isolation of total cell-free RNA. Recover up to 515 times more microRNA.
  • Ultra-Pure: Ready for Next-generation sequencing, RT-qPCR, nCounter, etc.

The Quick-cfRNA Serum & Plasma Kit enables simple, reliable, and efficient preparation of high-quality circulating cell-free RNA (including protein-bound, exosomal, miRNA and other small RNAs) from serum, plasma and other biological fluids. The kit does not use toxic phenol-chloroform or cumbersome protein precipitation and removal steps. Recovered cell-free RNA scales linearly relative to the sample input volume up to 3 ml. ZymoSpin™ Technology enables isolation of ultra-pure cell-free RNA suitable for all subsequent analyses, such as RT-qPCR and NGS. Empower your discovery of circulating RNA biomarkers.

Elution VolumecfRNA can be eluted into 15 µl (to maximize total yield) or as little as 6 µl (for highly concentrated eluate) of DNase/RNase-Free Water.
Processing TimeTypically requires 30 minutes hands-on time to process 10 samples. Sample digestion requires 2 hours.
PurityHigh quality cell-free RNA (cfRNA) is ready for all sensitive downstream applications such as RT-qPCR and Next-Generation Sequencing.
Required EquipmentMicrocentrifuge, vortex, water bath or heating block, vacuum, and vacuum manifold.
Sample TypeUp to 3 ml of plasma, serum, cerebrospinal fluids, amniotic fluids, urine, or other biological fluids.
SizeRNA ≥ 17 nt.
YieldYields are sample dependent and may vary. Typical recovery ranges from 1 – 100 ng/ml of human plasma or serum. Kit is optimized for recovery of total cfRNA, including small RNA and microRNA.

Q1: Can saliva be used as sample input?

Saliva must be cleared to remove debris/mucus (12,000xg for 15 min at room temperature). Up to 1 ml cleared salvia can be used per extraction.

Proportional scale up relative to input volume (from 0.2 ml to 1 ml; 55y male plasma). Triplicates of purified samples used to generate RT-qPCR (Bioline; EPIK miRNA Select Kit, hsa-miR-16-5p assay).

2x and 8x more yields achieved from low and high input volumes, respectively, compared to the next best product from other supplier. Triplicates of purified samples from different kits used to generate RT-qPCR data (Bioline; EPIK miRNA Select Kit, hsa-miR-16-5p Assay). Kit from competitor Q cannot process input volume higher than 0.2 ml. Common sample source used (55y male plasma).
