Human embryonic kidney (HEK) 293T cells (ATCC, CRL-11268) were grown in DMEM (Gibco) plus 10% FCS (Gibco). Transfection assays were performed using Lipofectamine 2000 (Invitrogen, Thermo Fisher Scientific)-based method. 293T cells were transfected with vectors expressing either N or Nefmut/N, and supernatants harvested from 48 to 72 h after transfection. EVs were recovered through differential centrifugations by centrifuging supernatants at 500 × g for 10 min, and then at 10,000 × g for 30 min. Supernatants were harvested, filtered with 0.22 μm pore size filters, and ultracentrifuged at 70,000 × g for l h. Pelleted vesicles were resuspended in 1×PBS, and ultracentrifuged again at 70,000 × g for 1 h. Afterward, pellets containing EVs were resuspended in 1:100 of the initial volume.
Western blot analyses of both cell lysates and EVs were carried out as reported11 (link), and filters were revealed using 1:2000 diluted anti-flag M2 mAb from Merck (cat. H1029), 1:500-diluted anti-β-actin mAb (cat. 122625, Cell Signaling), 1:500 diluted anti-Alix Abs (PA5-52873 Invitrogen). Filters were analyzed by a Chemi-Doc apparatus (Bio-Rad) and relevant signals quantified by Image Lab software version 6.1.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
