Product Overview

04572877_img01.jpg

Fujifilm Wako has developed the MassivEV™ EV Purification Column PS, which utilizes our proprietary EV isolation and purification technology known as the PS affinity method1). Used in conjunction with the specialized MassivEV™ Purification Buffer Set (Product Number: 295-96601), this system enables convenient isolation and purification of EVs, including exosomes, from liter-scale cell culture supernatants.

About commercial or for-profit purposes

Please use this product for research purposes only. If you wish to use it for commercial or for-profit purposes, please contact Fujifilm Wako at wkuslabchem@fujifilm.com.

Features

  • High-purity EVs can be efficiently isolated and purified from large volumes of cell culture supernatants (from 10 mL to several liters)
  • Eliminates the need for expensive equipment like tangential flow filtration (TFF) systems. *Only a peristaltic pump is required.

Sample

Cell culture supernatant (e.g., MSC): From 10 mL to several liters

Note: Please use the MagCapture™ Exosome Isolation Kit PS Ver. 2 (Product No. 290-84103) when isolating EVs from 10 mL or less of cell culture supernatant.

*1 The volume mentioned is an approximate amount of MSC culture supernatant that can be processed in a single purification. The sample volume required may vary depending on the concentration of EV particles present in the cell culture supernatant. Note that the same column can be reused multiple times for processing the same sample. Fujifilm Wako has confirmed that the column can be used repeatedly up to five times, comprising one initial use and four subsequent repeat uses.
*2 This information is based on studies using EVs derived from MSCs. Results may vary depending on the cell type and other conditions.

Principle

The PS affinity method, Fujifilm Wako’s proprietary EV isolation technique, utilizes the Tim4 protein, which specifically binds to phosphatidylserine (PS) present on the surface of EVs. The high specificity of the PS-Tim4 interaction, coupled with the gentle elution by a chelating agent, enables the isolation of high-purity EVs in their intact state.

Protocol

Cell Culture
Step
01
Cell Culture
Culture the desired cells, facilitate cell proliferation and EV production, and collect the cell culture supernatant.
Sample preparation
(> 2 hr)
Step
02
Sample Preparation
Add EV Binding Enhancer to the cell culture supernatant.
Step
03
Pretreatment of Cell Culture Supernatant
Remove impurities by centrifugation or filtration.
Step
04
Degassing
Heat the cell culture supernatant so that it exceeds room temperature (25-28°C) and filter it through a filter.
Processing with a column
(> 7 hr)
Step
05
First Washing
Bring the column to room temperature and pass the Washing Buffer through the column.
Step
06
Sample Reaction
Pass the cell culture supernatant through the column, allowing the PS on EVs to react with the Tim4 protein on the resin.
Step
07
Second Washing
Pass EV Binding Enhancer/Washing Buffer through the column to wash the resin.
Step
08
Elution
Replace 50% of the EV Binding Enhancer/Washing Buffer in the column with EV Elution/EV-Stabilizer Buffer. Then, place an EV collection tube below the column and allow the EV Elution/EV-Stabilizer Buffer to flow through it to collect the EVs.
Step
09
Column Storage
After flushing the column with Washing Buffer, circulate 20% ethanol/Storage Buffer through the column. Secure the top of the column with Parafilm and store in a refrigerator at 2-10°C.
Buffer exchange
(30 min to 1 hr)
Step
10
Buffer Exchange
Exchange the buffer using either gel filtration or size-exclusion filtration techniques.

Data

Performance Data

EV isolation and purification from MSCs cell culture supernatant

Bone marrow-derived MSCs were cultured in the proliferation medium (MSCulture™/10% FBS) and then in the EV production medium (EV-Up™). The cell culture supernatant was collected and filtered through a 0.22 μm filter. EVs were isolated and purified from 200 mL of the filtered cell culture supernatant using the four methods described below. The solutions containing the purified EVs were subsequently analyzed using Nanoparticle Tracking Analysis (NTA), ELISA and BCA method.

[Isolation and purification method]

TFF
Only Tangential flow filtration (500 kDa)
TFF+AEX

TFF+SEC

(1) Particle analysis by NTA

[Result]
MassivEV™ yielded a greater number of particles compared to TFF+AEX or TFF+SEC, but fewer particles were obtained compared to TFF alone.

(2) Comparison of EV recovery as measured by CD63 ELISA and CD81 ELISA (n=3)

04572877_img07.png

[Result]
MassivEV™ achieved a higher rate of recovery of EVs compared to conventional methods.

(3) Number of particles per protein

The ratio of protein:particle is a useful indicator of EV purity5). The total protein content in the collected EV solution was measured using the BCA method, and the particle count was determined by NTA. The number of particles per 1 μg of protein was then compared.

[Result]
Using MassivEV™ resulted in a higher number of particles per 1 μg of protein compared to traditional methods, indicating that EVs with higher purity can be recovered.

Example of a purification system using the MassivEV EV Purification Column PS
How should I choose between centrifugation and filtration for the pretreatment of cell culture supernatants?
Your choice between centrifugation and filtration will depend on the facilities, instruments, and equipment your laboratory already has. The decision does not need to be influenced by the sample type or its specific application.
For buffer exchange, how should I choose between gel filtration and ultrafiltration?
We recommend gel filtration when the sample is for administration to animals.
What volume of the EV solution is obtained during elution?
The volume is 4 mL for a 1 mL column, and 20 mL for a 5 mL column.
How long can a column wrapped in Parafilm be stored?
Based on our experience at Fujifilm Wako, a column can be stored for approximately 1.5 months.
Can the column be used multiple times?
The column can be reused for the same sample up to 5 times, including the initial use and four subsequent reuses.
For each reuse, begin with Cleaning 1, as detailed in the "Procedures" section (5) of the instruction manual.

Troubleshooting

How should air that has entered the column be removed?
To remove air from the column, try passing 20% or 70% ethanol through it at the flow rates specified below. Note that prolonged or repeated exposure to air can degrade the resin's performance. For more information, consult the instruction manual.
