Gap Closure Assays

Our Gap Closure Assays provide a simple, convenient format to monitor cell migration with precision and accuracy. Each of these assays provides a consistently defined area across which migratory cells can move. Migration can be monitored in real time by microscopy.

Gap Closure Assays are available in the following formats:

  • Radius™ Cell Migration Assays use a biocompatible hydrogel to create a circular area across which cells can migrate in two dimensions.
  • Our CytoSelect™ Wound Healing Assay is a more consistent alternative to the traditional scratch assay. A precision-molded insert creates a consistent 0.9 mm linear gap at the bottom of a 24-well plate across which cells can move.
