Flow cytometry overlay histogram showing left Malme-3M positive cells and right negative HEK293 stained with ab210546 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilised with 0.1 % PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS containing 10% normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab210546) (1x 106 in 100μl at 0.2μg/ml (1/10500)) for 30min at 22°C.

The secondary antibody Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed was incubated at 1/4000 for 30min at 22°C

Isotype control antibody (black line) was Recombinant Rabbit IgG, monoclonal [EPR25A] - Isotype Control used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

Acquisition of >5000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter.

This antibody gave a positive signal in Malme-3M Fixed with 4% formaldehyde (10 min) / permeabilised with 0.1 % PBS-Triton X-100 for 15 min under the same conditions.

Schematic and characterization of hNVs.a Schematic showing the hNVs consist of engineered SαV-C-NVs, M1-NVs, and P-NVs. b Schematic showing the hNVs efficiently interact with CTCs in the blood, accumulate in the post-surgical tumor bed, repolarize TAMs towards M1 phenotype, and block the CD47-SIRPα ‘don’t eat me’ pathway, thus promoting macrophage phagocytosis of cancer cells, as well as boosting antitumor Tcell immunity. c, d Immunofluorescence imaging c and flow cytometry analysis d of SαV expression on original and engineered B16F10 cells. Scale bar, 10 µm. e Relative mRNA expression of Cd86, Tnf, Il6, and Inos in M0 cells, M1 cells, M0-NVs and M1-NVs. f Hydrodynamic size and zeta potential of P-NVs, M1-NVs, SαV-C-NVs, and hNVs measured by DLS. g TEM images of hNVs.
