Can qEV columns separate labeled exosomes?

Some downstream application require exosome samples to be labeled (e.g. PEG, PKH). 

 

The qEV columns are able to separate any labeled exosomes. For example, the qEV columns can separate PEG-ylated exosomes as long as the PEG is tightly bound to the exosomes. The PEG might change the size of the exosomes slightly, depending on the PEG chains, so the exosomes might come out in slightly different fractions to non PEG-ylated exosomes.
