IGF-1R protein is highly expressed on the surface of Expi293 cell membrane. Flow cytometry analysis with 1 μg/mL Anti-IGF-1R (teprotumumab biosimilar) mAb (orb1826913) on Expi293 cells transfected with human IGF-1R (Blue histogram) or Expi293 transfected with irrelevant protein (Red histogram), and Isotype antibody on Expi293 transfected with irrelevant protein (Orange histogram).

Flow cytometry analysis of antigen binding of anti-human IGF-1R mAb (orb1826913). (A) orb1826913 does not bind to Jurkat cells that do not express IGF-1R. (B) A clear peak shift of orb1826913 was seen compared to the control when incubated with IGF-1R-expressing Hela cells, indicating strong binding of orb1826913 to IGF-1R. Antibodies were incubated at 5 μg/mL.
