Exo-spin™ 96 provides proven size exclusion chromatography (SEC) mini-column (EX01) technology in a 96-well format, allowing up to 96 individual samples to be processed in less than 30 minutes. Sample volumes up to 0.5 ml can be purified.
The kit provides flexibility with 8-column strips detachable from the plate, so you can process 8 samples in 8-column strips if needed
The Exo-spin™ 96 well product offers:
- High-throughput exosome isolation at the benchtop in the standard 96 well format in under 30 minutes
- Purify up to 0.5 ml of each sample
- >97% of free proteins removed
- Outstanding reproducibility +/- 5% Standard deviation, for consistent exosome purification, time after time
- Flexibility to just work with single strips of 8 columns at a time
- The convenience of purified exosomes eluted directly into a 96 well plate ready for high throughput downstream applications
The Exo-spin™ 96 can be used to isolate exosomes directly from protein-rich samples such as sera and plasma. If required, you can concentrate the sample with your preferred concentration method (e.g. concentrator, precipitation buffer) to isolate from large volumes of low-protein biofluids, such as cell culture medium, cerebral spinal fluid (CSF), and urine.
The EX07 Exo-spin™ kit has been developed to process up to 500 µl blood samples (plasma or sera using iterative loading

Exo-spin™ column and resin pore size
The column bed volume in EX07 Exo-spin™ 96 plate is 500 µl. 100 µl of the sample may be loaded onto each column. Iterative loading allows up to 0.5 ml sera in total to be purified.
The pore size within the resin is approximatively 30 nm. Free molecules (e.g. proteins, lipids) which are smaller than 30 nm will enter into the pores within individual resin beads and their movement through the column is slower.
Highest recovery and purity
Blood plasma and sera typically contain around 1 x 1012 exosomes/ml. Size exclusion chromatography (SEC), provides a superior to technique to purify exosomes from blood. Samples can be added directly onto the column or concentrated, if required, prior to application. Exosomes in a range 30-250 nm will elute in the first fraction. >95% of free, non-exosomal proteins and lipids will be retained in the column and will elute later than the exosomes, ensuring a highly pure sample ready for downstream application.
Reproducible purification provides the starting point to reproducible data. Exo-spin™ 96 columns provide excellent reproducibility with a standard deviation for exosome yield of just 5%. All Cell Guidance Systems columns are manufactured in our own manufacturing facility using advanced production techniques and quality control systems. This ensures the high reproducibility between each and every column within and between purification plates. A large number of peer-reviewed scientific papers have been published describing research which has been enabled by the use of Exo-spin™.

Exo-spin™ comparative data
Exo-spin™ shows superior yield and purity. Data determined by nanoparticle tracking analysis (NTA). Each curve represents the average of 3 technical replicate measurements for each exosome isolation method and biofluid triplicate experiment. (PM = Precipitation Method). Data generated for Exo-spin mini columns which have the same resin and measurements. Adapted from (Martins, TS et al., 2018).
Data determined by NTA and EXOCET. Serum sample has been analysed for qualitative comparison between Exo-spin™ and precipitation methods.
