How It Works

How It Works

ExoQuick®-TC UltraPure uses a dual-action workflow: ExoQuick® precipitation captures >90% of EVs, followed by a mixed-mode affinity column that removes albumin, IgG, and lipoproteins in a single pass. No ultracentrifuge. No pre-concentration. Under 20 minutes of hands-on time.

ExoQuick®-TC UltraPure 5-step workflow diagram showing EV isolation from 10 mL and 100 mL cell culture conditioned media

Figure 1. The simple ExoQuick®-TC UltraPure workflow ExoQuick reagent captures virtually all EVs in a sample, achieving over 90% EV recovery. This is followed by a specialized chromatography column that enhances separation by combining size-based and chemical-property-based mechanisms, removing BSA, IgG, and lipoproteins.

Simple 5-Step Workflow (10 mL to 1 L compatible):

  1. Step 1 — Add ExoQuick® to conditioned media
  2. Step 2 — Mix and incubate at 4°C
  3. Step 3 — Centrifuge to pellet EVs and discard supernatant
  4. Step 4 — Resuspend and load onto the purification column
  5. Step 5 — Collect purified EVs from the flow-through

Total hands-on time: <20 minutes. No ultracentrifuge. No pre-concentration. No specialized equipment.

ExoQuick®-TC UltraPure Delivers >50× Higher EV Yield vs. SEC

EV isolation yield and purity comparison chart showing ExoQuick TC UltraPure vs SEC qEV ultracentrifugation and TFF with higher EV recovery and lower protein contamination

Figure 2. ExoQuick®-TC UltraPure provides higher EV yield and purity compared to other isolation methods. EVs were isolated from HEK293 cell culture medium using ExoQuick®‑TC Ultra, ExoQuick®‑TC UltraPure, size‑exclusion chromatography (SEC)–based qEV, ultracentrifugation, and tangential flow filtration (TFF). EV particle numbers from each method were quantified by NTA. NTA confirms that ExoQuick®‑TC UltraPure delivers superior EV yield and purity, as shown by both the volume of input culture medium used per 10 mL (A) and the input protein amount per mg (B). EV protein levels were quantified using the Qubit assay.

EQ-TC UltraPure = Cleaner EVs, Near-Complete Lipoprotein Removal

Western blot and ApoB ELISA comparison showing ExoQuick TC UltraPure vs qEV with higher EV markers and near-zero lipoprotein contamination

Figure 3. ExoQuick®-TC UltraPure delivers higher yield and superior purity compared to SEC-based qEV. Culture medium (10 mL) from the XPACK530 HEK293 stable cell line – containing copGFP-loaded EVs – was used for isolation. (A) Western blot analysis shows that EVs isolated with ExoQuick®-TC UltraPure contain higher levels of EV-specific markers and exhibit minimal albumin carryover compared to the SEC-based qEV method, indicating both higher yield and superior purity. EV integrity is also well preserved, as indicated by robust copGFP expression. (B) ApoB ELISA analysis reveals that EVs isolated using ExoQuick®-TC UltraPure contain nearly undetectable ApoB levels, confirming minimal lipoprotein contamination.

FAQs

The Small Kit (EQ-TC UltraPure_S) processes 10 mL of conditioned media per reaction. The Large Kit (EQ-TC UltraPure_L) processes 100 mL per reaction. Both kits provide 10 reactions. For scale-up beyond 100 mL — including 1 L bioreactor harvests — contact our technical support team for guidance and bulk options.
The dual-action workflow removes three major contaminant classes: albumin (BSA), IgG, and lipoproteins. Near-complete lipoprotein depletion is confirmed by ApoB ELISA. Albumin and IgG removal is validated by Western blot and Ponceau S staining.
Yes, with one important distinction. The kit is fully compatible with in-gel digestion workflows (trypsin, pepsin) because PEG — the precipitation reagent — does not migrate into the gel and does not interfere with MS analysis. For in-solution digestion workflows, PEG can cause ion suppression and background signals. We recommend consulting with your proteomics facility or contacting our technical team before proceeding with in-solution digestion. For EV proteomics using precipitation-based methods, we also recommend reviewing our application note on EV precipitation vs SEC for proteomics workflows.
Yes. ExoQuick®-TC UltraPure is validated for use with both standard tissue culture flask media and large-scale bioreactor harvests. Unlike SEC and TFF, it requires no pre-concentration and no ultrafiltration — making it well-suited for therapeutic EV development and cell therapy production workflows where maintaining yield and purity at scale is critical.

ExoQuick®-TC UltraPure outperforms both SEC (e.g., qEV) and tangential flow filtration (TFF) in yield and purity for cell culture media applications.

vs. SEC (qEV): Delivers more than 50× higher EV yield, with superior removal of albumin, IgG, and lipoproteins. SEC requires pre-concentration of conditioned media before loading — ExoQuick®-TC UltraPure processes your sample directly, no pre-concentration required.

vs. TFF: At equivalent large-volume inputs (100 mL), EQ-TC UltraPure produces significantly cleaner EV preparations — confirmed by Ponceau S staining and Western blot — with higher EV marker expression and lower protein contamination. Unlike TFF, no specialised tangential flow filtration system is required.

EVs isolated with ExoQuick®-TC UltraPure are validated for:

  • Nanoparticle Tracking Analysis (NTA)
  • Transmission Electron Microscopy (TEM)
  • Western blot (EV marker detection)
  • ELISA
  • RNA extraction, small RNA/miRNA sequencing, and next-generation sequencing (NGS) — compatible with SBI's NGS service
  • Mass spectrometry proteomics (in-gel digestion)
  • EV uptake and cargo delivery assays
  • In vivo / ex vivo administration studies
Yes. TEM confirms that vesicles retain their native bilayer membrane morphology after isolation. Functional validation using copGFP-loaded EVs from the XPACK530 stable HEK293 cell line demonstrates that engineered EV cargo is fully preserved through the isolation workflow, confirming suitability for cargo delivery and functional studies.
No. ExoQuick®-TC UltraPure requires no ultracentrifuge, no pre-concentration equipment, and no ultrafiltration system. The entire workflow is completed using standard laboratory benchtop equipment in under 20 minutes of hands-on time per reaction.
