Figure 3. Most of the Lipoproteins are removed in sEV isolated with SmartSEC-DeLipoTM. (A) ApoB and ApoE lipoproteins’ concentrations were evaluated in serum sample, sEV isolated from serum with SmartSECTM single and sEV isolated from serum with SmartSEC-DeLipoTM by ELISA. SmarSECTM single dramatically reduced Lipoproteins in isolated sEV and SmartSEC-DeLipo further deplete the remaining Lipoproteins in yield sEV. (B) Percentage of ApoB and ApoE depletion was calculated based on ApoB and ApoE concentration in sEV isolated with SmartSEC-DeLipoTM vs. SmartSECTM single from serum, plasma and breast milk samples.

Figure 2. sEV isolated with SmartSEC-DeLipoTM is much purer. (A) sEV isolated from 250ul of serum with SmartSEC-DeLipoTM shows higher expression of EV markers, such as CD9, CD81 and TSG101 than those isolated with SmartSECTM single when same amount of EV protein were applied for western blot. When same volume of eluted sEV samples were applied for western blot, EV markers’ expression is about the same for sEV isolated from 250ul of serum with SmartSEC-DeLipoTM or SmartSECTM single. (B) sEV isolated from 250ul of plasma or breast milk with SmartSEC-DeLipoTM shows higher expression of EV markers, such as CD9, CD81 and TSG101 than those isolated with SmartSECTM single when same amount of EV proteins was applied for western blot. (C) fNTA data shows that sEV particle number were decreased in plasma or breast milk sample when isolated with SmartSEC-DeLipoTM in comparison with that isolated with SmartSECTM single. However, when purity was evaluated with EV particle number per same amount of

Figure 5. sEV isolated with SmartSEC-DeLipoTM is biologically functional to delivery small RNA cargo to the recipient cells. (A) Cy3-labeled control siRNA were loaded without or with sEV isolated from serum with SmartSECTM single or SmartSEC-DeLipoTM using Exo-Fect siRNA/miRNA reagent (EXFT200A-1) and delivered to HEK 293 cells. Cells imaged 36-48 hours post transfection. Shown are the bright-field images (bottom row), and fluorescence images (top row). Both sEV isolated with SmartSEC single or SmartSEC-DeLipoTM can efficiently transfer Cy3-labeled siRNA to most of the imaged cells. (B) HPRT siRNA were loaded without or with sEV isolated from serum with SmartSECTM single or SmartSEC-DeLipoTM using Exo-Fect siRNA/miRNA reagent (EXFT200A-1) and delivered to HEK 293 cells. Cells were lysed and applied for western blot 48 hours post transfection.

Description
Description: Purer EVs with Less LipoproteinsElevate your small extracellular vesicle (sEV) isolation game with our cutting-edge SmartSEC-DeLipoTM kit, engineered to provide unmatched purity and quality while efficiently depleting lipoprotein contaminants. Harnessing the power of SmartSECTM coupled with innovative lipoprotein removal technology, this kit streamlines the sEV isolation process, ensuring pure sEVs samples for downstream analyses.New generation of mixed-mode chromatographyAdvanced Lipoprotein DepletionFast and Easy Isolation of High Yield and Purity sEVVersatile Compatibility with Various ApplicationsOverviewImportance of Removing Lipoproteins from sEVExtracellular vesicles (EVs) from blood are of great importance to understand the biological role of circulating EVs and to develop EVs as biomarkers of disease. However, isolating EVs from blood poses challenges due to the simultaneous presence of lipoprotein particles. Lipoproteins may interfere with downstream analyses or functional assays performed on EVs. For instance, lipoproteins contain microRNAs as their cargos. In studies investigating the biological roles of EVs or their potential as biomarkers, the presence of lipoproteins could confound the results or mask the true effects of EVs. Recently, several studies showed that ultracentrifugation or size exclusion chromatography (SEC) alone cannot completely separate blood EVs from lipoprotein particles. Therefore, improved separation of EVs from lipoproteins is crucial for a detailed functional analysis of circulating EVs, thus making blood a viable source for EV biomarker discovery.Advanced sEV Isolation with SmartSEC-DeLipoOur cutting-edge SmartSEC-DeLipoTM kit was engineered to provide unmatched purity and quality while efficiently depleting lipoprotein contaminants for sEV isolation. Harnessing the power of SmartSEC coupled with innovative lipoprotein removal technology, this kit streamlines the sEV isolation process, ensuring much purer sEVs samples for downstream analyses.New generation of mixed-mode chromatography: Our SmartSEC-DelipoTM Kit utilizes SmartSECTM columns, a new generation of mixed-mode chromatography, which provides the dual functionality of size exclusion and affinity interaction modes.
