Fig. S1 Characterization of the anti-CAR SIV antibodies against human and zebrafish CAR. Immunofluorescent and immunoblot analysis of human (hCAR) and zebrafish (zCAR) CAR transfected QBI-293A cells (293). The anti-CAR SIV antibodies detected exogenously expressed hCAR and zebrafish zCAR at cell–cell contacts as well as at the cell-surface of transfected 293 cells (A and B, respectively). Immunoreactivity of the antibody against endogenously expressed hCAR in 293 cells is indicated with arrowheads (A and B). (C) The anti-CAR SIV antibodies react with an approximately 47 kDa protein band in cell lysates from exogenously expressed hCAR and zCAR in transfected 293 cells (lanes 2 and 3, respectively). Endogenously expressed hCAR was used as control for the molecular size (lane 1). The position of the molecular weight marker (kDa) is indicated to the left.
