Why don’t you offer kits with 24-well plates?

Each well in a 24-well plate is substantially larger than wells in 96-well plates. Consequently, each data point requires more cells, more culture medium, more additives, and more time to complete the assay. That’s expensive. Moreover, 24-well migration and invasion assay plates provided elsewhere cost about the same or more than Oris™ 96-well plates, so your costs quadruple per data point before you even start the assay.
