Purified Exosomes

Purified exosomes ready to use from human cell lines for consistent EV studies

These preparations skip the in-house isolation step, taking you straight to defined, characterised EV material that gives a consistent reference point for positive controls, uptake studies, and functional assays across experiments and laboratories. EV preparations come from defined human cell lines, including cancer-derived and standard expression lines, with confirmed size distribution and, for many preparations, tetraspanin surface marker data that supports comparison between laboratories. Where characterisation data are provided, lots are assessed by nanoparticle tracking analysis confirming a mean particle diameter of 100 to 200 nm, and by western blot for tetraspanin markers CD63, CD81, and/or CD9. Cancer-derived EVs suit your tumour biology uptake studies or cargo analysis, while HEK293 EVs serve as the standard production cell line for cargo-loading experiments and as a reference preparation in EV engineering work.
