Overview

Get outstanding SEC-based EV isolation with SmartSEC™ Single

SmartSEC Single uses the same proprietary chromatography-based extracellular vesicle (EV) isolation technology as our popular SmartSEC HT plate and SmartSEC Mini kit but in a single tube format. SmartSEC technology combines all the benefits of size exclusion chromatography (SEC)—purity, yield, reproducibility, and preservation of EV integrity—with a contaminant trapping feature that enhances the capabilities of conventional SEC. The result is best-in-class EV isolation that is fast, easy, and clean.
  • Quick and easy isolation

  • Compatible with most downstream applications such as mass spectrometry, western blotting, nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM) and RNA-sequencing (NGS)
Each SmartSEC Single Kit comes with sufficient individual SmartSEC columns and buffer to process 10 samples.

How It Works

The SmartSEC Single workflow is fast and easy. Simply apply 100 – 250 µL of cleared serum or plasma with additional column buffer or up to 4 mL of other biofluids directly to the pre-washed column, incubate, and centrifuge to elute the EVs.
 

Supporting Data

SmartSEC Single performs better than competitor’s q SEC technology

To understand how well SmartSEC Single performs compared to a competitor’s q SEC columns, we isolated EVs from 250 µL of human serum using both SmartSEC Single and q SEC columns and analyzed 1 µg of protein equivalent from each isolation method on a western blot (Figure 1) and using fluorescent nanoparticle tracking analysis (fNTA, Figure 2).
 
EVs isolated using SmartSEC Single show lower levels of carry-over proteins such as albumin and IgGs (Figure 1) and a higher number of particles per mg of protein (Figure 2) than EVs isolated using the q SEC columns, demonstrating the higher purity delivered by SmartSEC Single. In addition, SmartSEC Single delivered EVs at ~6-fold higher concentration than the q SEC columns (Figure 1), for overall superior performance.
 

SmartSEC Single cleanly isolates EVs from CSF

SmartSEC Single can isolate EVs from cerebrospinal fluid (CSF) with no detectable cellular contamination, as shown in the ExoCheck Neuro Array in Figure 3. The isolated EVs possess both neuronal and exosomal markers, suggesting that the EV prep is enriched for vesicles of neuronal origin. Interestingly, EVs isolated from CSF tend to be smaller in size than EVs isolated from serum (Figure 4).
 
 

EVs isolated using Smart

(TEM) of EVs isolated from serum using SmartSEC Single possess typical EV morphology—intact vesicles with a double layer of membranes—with little visible background debris (Figure 5).
 
 
 

EVs isolated with SmartSEC Single and a competitor’s q SEC columns have very similar proteomic profiles.

We analyzed EVs isolated from human serum using SmartSEC Single and a competitor’s q SEC columns using mass spectrometry. Both methods yielded very similar proteomes, with 86% overlap (Figure 6).
 
 

SmartSEC Single can be used to isolate EVs for downstream proteomic studies.

To demonstrate the versatility and power of SmartSEC Single for enabling EV research, we used SmartSEC Single technology to isolate EVs from normal serum and serum from prostate cancer patients and used mass spectrometry to analyze the respective proteomes.
