  • Surface of a vessel with polystyrene, nitrogen, oxygen and a static sessile contact angle for attachment and cultivation of cells
    Patent number: 11001802
    Abstract: The present invention relates to the field of mammalian cell culture, and provides methods and compositions for cell attachment to, cultivation on and detachment from a solid substrate surface containing from at least about 0.5% N, a sum of O and N of greater than or equal to 17.2% and a contact angle of at least about 13.9 degrees, lacking a feeder cell layer and lacking an adlayer. In one embodiment of the present invention, the cells are treated with a compound capable of inhibiting Rho kinase activity. In another embodiment, the cells are treated with a compound capable of inhibiting Rho activity.

  • Method of stabilising or reactivating a creatinine sensor with a divalent manganese ion
    Patent number: 7888061
    Abstract: A method is provided for stabilizing a creatinine sensor comprising creatininase as a bioactive molecule. The creatininase is stabilised by exposing it to a sufficient amount of a divalent manganese ion. This result may be obtained by exposing the sensor to a solution comprising the divalent manganese ion or by introducing a composition within the sensor providing sustained release of the divalent manganese ion.
