Exo-spin™ 96 (EX07 for blood sera and plasma)

Exo-spin™ 96 (EX07 for blood sera and plasma)

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.

Downstream applications: advice and content

The EX07 Exo-spin™ 96 kit is compatible with all downstream application and has been published in a large range of different applications.
