Fluorescent microscopy analysis of heterotypic interactions of E. coli cells expressing different variants of Ag43. (A) Co-culture of SRUD-Green Ag43^C1-PT (C1) and SRUD-Red Ag43^C2-PT (C2). (B) Co-culture of SRUD-Green Ag43^C2-PT and SRUD-Red Ag43^C4-PT (C4). (C) Co-culture of SRUD-Green Ag43^C1-PT and SRUD-Red Ag43^C3-PT (C3). (D) Co-culture of SRUD-Green Ag43^C2-PT and SRUD-Red Ag43^C3-PT. (E) Co-culture of SRUD-Green Ag43^C1-PT and SRUD-Red Ag43^C4-PT. (F) Co-culture of SRUD-Green Ag43^C3-PT and SRUD-Red Ag43^C4-PT. The NA, C1, C2, C3 and C4 labels match the colour of the fluorescent bacterial strains.
