Which antibody is more effective to bind/capture exosomes when immobilized on magnetic bead support?

11 November 2017 0 815 Report

I am coating epoxy magnetic beads (Dynabeads TM M-270 Epoxy) with anti-CD63 antibody to bind/capture and purify exosomes from urine and serum. We are having some mixture of particle sizes, so we believe there are not only exosomes in our bead-bound fractions, even if purity is already quite high. I would like to know if there is an even more specific marker on the surface of exosomes to use the corresponding antibody coupled on beads. Thank you

What could be some reasons why unstimulated monocytes are getting activated?

Im doing PBMC isolation -> CD14+ enrichment using magnetic beads -> stimulation setup. My negative control is just cells in cRPMI but they seem to get activated over and over again.
