Lungs were collected at 38 dpi. Three different levels were taken from formalin-fixed and paraffin-embedded lungs sectioned 100 µm apart. Slides were H&E stained, scanned, and analyzed using HALO to obtain summed lung metastasis counts and c percent tumor area over normal lung tissue. Two mice in the vehicle group were removed due to inconsistencies between HALO results and physical examination of H&E slides.

Quantification of EV concentrations with the 300-nm CuS-MG in 1× PBS or Serum. Calibration curves in 1×PBS using a) anti-CD63, b) anti-HER2; and in serum using c) anti-CD63 or d) anti-HER2. CL0 = chemiluminescence without EVs. [ABEI] = 0.5 mM, [H2O2] =1 mM, pH=11.

Article Snippet: The biotinylated mouse anti-human ErbB2/HER2 (Recombinant Monoclonal Human IgG 1 Clone Hu5), mouse anti-human CD63 (Clone mem-259), and biotinylated mouse anti-human CD63 (Clone NVG-2) was obtained from R&D systems, Sino Biological, and BioLegend, respectively.

Techniques:

Detection of cell released EVs using CuS-MG. The cell culture medium was collected from three cell lines: MCF-10A, MDA-MB-231 and SK-BR-3. a) Chemiluminescence resulted from EV detection in the culture media of three cell lines targeting CD63 and anti-HER2; b) PCA plot using the chemiluminescence data shown in a); c) Linear correlation between CD63 quantification results obtained by ELISA and the chemiluminescent signals from CuS-MG in our assay targeting CD63. [ABEI] = 0.5 mM, [H2O2] = 1 mM, pH=11.
