This platform is capable of quantitative exosomal biomarker profiling directly from 30 ?L plasma samples within approximately 100 minutes with markedly enhanced sensitivity and specificity. Identification of distinct subpopulation of patient-derived exosomes is demonstrated by probing surface proteins and multiparameter analyses of intravesicular biomarkers in the selected subpopulation. The expression of IGF-1R and its phosphorylation level in non-small cell lung cancer (NSCLC) patient plasma is assessed, as a non-invasive alternative to the conventional biopsy and immunohistochemistry.
