Fig. 3From: Development of a human phage display-derived anti-PD-1 scFv antibody: an attractive tool for immune checkpoint therapySpecificity of the selected anti-PD-1 scFv. The binding specificity of the soluble anti-PD-1 SS107 scFvs to several immobilized peptides and proteins was determined through ELISA. The data are presented as mean ± SD from triplicate experiments. Peptides: c-Met,4-1BB (CD137), IGF-1R, ROR1, Fzd7. proteins: PD-1, skim milk, and BSABack to article page
