AggreWell™ plates bring an easy, standardized approach to the generation of cell aggregates, including embryoid bodies (EBs) and spheroids. EBs and spheroids generated using AggreWell™ plates are consistent in size and shape, and are uniform within and between experiments.  New and improved second-generation AggreWell™ plates are compatible with a variety of cell types, including ES and iPS cells, cancer cells and more. Enhanced optical characteristics provide crystal clear imaging. Note: Anti-Adherence Rinsing Solution is required for optimal EB and spheroid formation.
