Manage your cells with Mebiol Hydrogel!


Hydrogels are a diverse class of polymer materials that are characterized by their network-like structure and high water content. Hydrogels of many types find a wide range of applications in medicine and life science research, but are not limited to three-dimensional cell culture, tissue engineering and drug delivery. Properties that are very beneficial for cell culture and tissue engineering prompted the commercialization of Mebiol Gel, a copolymer of poly (N-isopropylacrylamide) and poly (ethylene glycol) (PNIPAAm-PEG) for research purposes in the early 2000s. In contrast to other commercially available hydrogels, the defining characteristic of Mebiol Gel is the temperature-reversible sol-gel transition. When cooled, Mebiol Gel is soluble (treated like a liquid), but becomes a rigid hydrogel at higher temperatures. In practice, this means that the cells are very easy to handle. The cultures are sown in chilled Mebiol gel and conveniently obtained by cooling the culture vessel and centrifuging. In the gel state, the highly lipophilic environment of the Mebiol Gel presents an efficient niche for cell proliferation, cell communication, gas and mass exchange and protection of cells and tissues from shear forces.
