Bio-Assembler Kits use magnetic levitation to culture cells in 3-D. Available in single, six and 24-well configurations, the kits supply magnetic drivers, low-binding dishes/plates, and Nanoshuttle-PL solution in quantities and volumes appropriate to kit size. Nanoshuttle-PL solution delivers magnetic nanoparticles to cells. The magnetic driver that nests on top of the dish/plate then levitates the cells to create a 3-D environment. Using the Bio-Assembler Kits is as easy as performing standard 2-D cell culture plating and propagation.
