TEM1-targeted drug delivery by scFv78. a Mouse endothelial cell line MS1 were incubated with serially diluted ZAP, scFv78 alone or scFv78-ZAP at the indicated concentrations. b MS1-hTEM1 positive cells were incubated with serially diluted ZAP, scFv78 alone or scFv78-ZAP at the indicated concentrations. Then the viability was measured by MTT 96 h later. *p < 0.05; **p < 0.01
