TABLE 1.

Particles per μg of protein of subgroup 1 (SG1) and subgroup 2 (SG2) of vesicles obtained from MDA‐MB‐468, HEK293T, and fibroblasts cells, using the Pre‐SEC method

Cell line	Particles/mg protein
	SG1	SG2
MDA‐MB‐468	1.26E+09 ± 8.9E+07	2.37E+08 ± 7.42E+07
HEK293T	9.55E+08 ± 2.25E+08	1.38E+08 ± 1.81E+07
Fibroblasts	7.96E+08 ± 4.60E+08	1.07E+08 ± 6.19E+07

All measurements were performed in triplicate for each subgroup of each cell line. Data intervals represent the SEM.
