Flow cytometric analysis of latex bead–coated exosomes derived from supernatants of Colo−/Colo+ and CX−/CX+ carcinoma sublines

MarkerSurface-positive exosomes (% ± SE) *
Colo− exosColo+ exosCX− exosCX+ exos
Hsp703 ± 384 ± 5 19 ± 1073 ± 3

  • Abbreviation: exos, exosomes.

  • * Data represent mean percentages of Hsp70 (cmHsp70.1), Bag-4 (IMG-152), and MHC I (W6/32) surface-positive exosomes of three independent experiments ± SE.

  • Significantly different from the corresponding negative cell type.
