Deletion of any of the extracellular domains of PTPρ disrupts cell-cell aggregation. Sf9 cells expressing deletion constructs of the individual extracellular domains of PTPρ were allowed to aggregate for 30 minutes prior to imaging. Scale bar equals 100μm. The percentage of Sf9 cell-cell aggregation for each deletion protein was calculated from a minimum of three experiments. An asterisk indicates a statistically significant reduction in aggregation (p<0.005).
