No. Many users are using unstained cells in combination with FMO controls to identify their positive populations.

The flow cytometry field is moving away from using isotype controls as they are not necessarily the most appropriate way to control for non-specific binding. Instead, they are using unstained cells to define the negative population, single stained controls to set compensation, and flow minus one (FMO) controls to set regions and gates.
You may want to consider whether using an isotype control is something you need to do. Here are some references you might want to look at:
