Figure Lengend Snippet: Hsp70 and CTR are present in SEC-purified EVs from GBM patients. ( A , B ) Western blot and statistical analysis for Hsp70, and ( A , C ) for CTR (loading 50 μg, and we used Cyt C as a negative control). From the left: lane 1, EVs derived from the plasma of healthy individuals (HV); lane 2, EV lysates derived from the plasma of GBM patients at T0; lane 3, EV lysates derived from the plasma of GBM patients at T1. The images are representative of at least 3 independent experiments. ( D ) Representative images of immunohistochemistry for CTR in normal tissue (NT) ( a , b ), and GBM tissue (GBMT) ( c , d ). ( a , c ): Magnification, 200×; scale bar, 50 µm. ( b , d ): Magnification, 400×; scale bar, 20 µm. The histogram shows the statistical analysis of the IHC data (* p ≤ 0.01). ( E ) Immunofluorescence images of CTR showing its presence in the primary and secondary cell lines. A specific primary antibody for the receptor and a secondary antibody conjugated with FITC (green fluorescence) were used, and the cell nuclei (blue) were stained with DAPI. Magnification, 400×.
Article Snippet: Sections were then incubated with the primary antibody for CTR (mouse monoclonal, 31/01-1H10-4-1-14 clone, BioRad cat. N°: MCA2191; dilution 1:100).
