Indirect fluorescent antibody detection of recombinant TgCPB and TgCPL proteases on the surface of HEK293 cells. (A1) pTgCPB-transfected HEK293 cells; (A2) pBudCE4.1-transfected HEK293 cells. (B1) pTgCPL-transfected HEK293 cells; (B2) pBudCE4.1-transfected HEK293 cells. (C1) pTgCPB/TgCPL-transfected HEK293 cells where pTgCPB/TgCPL expression was detected using the anti-TgCPB antibody as the primary antibody; (C2) pBudCE4.1-transfected HEK293 cells where the anti-TgCPB antibody was used as the primary antibody. (D1) pTgCPB/TgCPL-transfected HEK293 cells where the anti-TgCPL antibody was used as the primary antibody; (D2) pBudCE4.1-transfected HEK293 cells where the anti-TgCPL antibody was used as the primary antibody. High level of laser intensity was used for A1, A2, B1 and B2, lower level of laser intensity for C1, C2, D1 and D2.
