The plasma-isolated exosomes can be used as a non-invasive and repeatable way for the detection and follow-up of the biomarkers for early detection and disease progression. This video describes the protocol for the separation of exosomes from the plasma samples of non-small cell lung cancer patients, which could be used for DNA and protein extractions.
Protocol
1. Exosome Isolation Note: The isolation of exosomes from plasma samples, was performed with a commercial kit, according to manufacturer's protocol and by adding RNAse treatment: (all these steps must be performed with personal and environment protective equipments and following specific legal procedure for manipulation of biological samples). Take 1 ml of plasma of each sample, stored at -80 °C, and place it on ice. Centrifuge the sample at 2,00…
