Optimized exosomal RNA extraction for biomarker discovery and more—for serum, plasma, and ascites fluid

Looking for biomarkers? Studying exosomal RNAs (exoRNAs)? Turn to SBI’s SeraMir Exosome RNA Purification Kit for optimized isolation of exoRNAs. The kit includes ExoQuick for efficient exosome isolation from serum, plasma, or ascites fluid, and SeraMir columns and reagents for purification of RNA from your isolated exosomes (for exoRNA isolation from other biofluids, try the SeraMir Exosome RNA Purification Kit for Media and Urine).

Reliable, reproducible exoRNA isolation from serum, plasma, or ascites fluid

With cargo that reflects the makeup of their parent cells and their easy isolation, researchers are increasingly turning to exosomes as a source of disease-related biomarkers. To simplify and standardize the isolation of RNA from exosomes, SBI has developed the SeraMir family of products.

The SeraMir Exosome RNA Purification Kit includes everything you need for optimized isolation of exosomal RNAs from serum, plasma, or ascites fluid samples—ExoQuick for fast and efficient exosome isolation and a phenol-free lysis buffer and rapid spin columns to extract RNA from your isolated exosomes.

How It Works

Go from sample to amplified exoRNAs in a single day

  • Isolate exosomes from patient biofluids with the included ExoQuick reagent
  • Purify exoRNAs with SeraMir columns

Purified exoRNAs are fully compatible with most downstream applications, such as qPCR, microarray analysis, or NGS.

Isolate serum exosomes and purify exoRNAs

Tail exoRNAs and synthesize double-tagged cDNA

Use the SeraMir spike-in RNA control in a qPCR assay to control for exoRNA recovery, tailing, and cDNA synthesis

Supporting Data

Better qPCR profiling with SeraMir

Figure 1. Serum RNA prepared by the SeraMir Kit delivers more reliable, reproducible qPCR profiles than when the RNA is isolated using conventional Trizol methods. Profiling of 380 Human microRNAs across the SeraMir 384 Profiler. The phenol-free exosome lysis step coupled to the small RNA binding columns isolates exoRNAs with much higher purity than Trizol/Phenol based methods. The SeraMir exoRNAs are compatible with downstream polyadenylation and reverse trancription reactions for amplification and accurate qPCR profiling.

Figure 2. Serum exoRNAs prepared using SeraMir deliver excellent performance in microarray studies. Samples from a pooled normal serum preparation and from a male caucasian (age 73) with adenocarcinoma of the colon were used in this study. Exosomes were precipitated from 250 µL of serum using the SeraMir Exosome RNA Amplification Kit. The T7-amplified “sense” exoRNAs were then used for direct labeling analyses on LC Sciences miRBase ver.16 array chips (performed in triplicate). The exoRNAs were hybridized across 1,214 different microRNAs on the probe set.
Of the 1,214 microRNAs analyzed, 79 microRNAs showed a signal intensity >32. Within this set of 79, there was a clear colon versus normal “signature set” of 40 microRNAs that could discriminate normal from colon cancer serum samples with a p-value < 0.01. The identities of the microRNAs found in this study have been masked while further investigation continues.
