Comments concerning this interaction

Source was intact S2 cells; proteins produced from transfected constructs.

(Dworak et al., 2001)

S2 cells expressing hbs were mixed with S2 cells expressing kirre : each cell type was labeled by a different dye. The formation of cell clusters containing both kirre and sns expressing cells was assayed by fluorescence microscopy.

Comments concerning this interaction

Source was live S2 cells; proteins produced from transfected constructs.

(Shelton et al., 2009)

Physical interaction of proteins expressed on the surface of cells is inferred from the aggregation of live cells.
