Protista provides products and services for cell separation, cell culture and tissue engineering. The company is a leader in development and production of supermacroporous functionalized monoliths (cryogels) from a variety of synthetic and natural polymers. Cryogels produced by Protista are excellent adsorbents for cell chromatography and cell culture. Cryogel monoliths SepA, HTS E and Cryogel E are the brand products which provide selective binding and highly efficient recovery of bound cells. Products Cryogel 3D CellGrow96 and CellGrow48 provide three-dimensional environment for cell growth in a multiwell plate format and are excellent platforms for cell-based assays. Protista is constantly working on new products and is focused on three-dimensional biodegradable matrices for stem cell cultures. The company offers services for tissue engineering laboratories with the goal of becoming a supplier of customized monoliths, tailored properties and high efficiency in clinical use.
If you look into the options for cell separation, Protista has developed special types of gels made out of polymers that binds cells and then deforms to release cells without harming them.
