Estimating the term…
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.
A method to enhance the attachment of cells to a 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, comprising the steps of:
A method to enhance the attachment of cells to a surface containing from at least about 0.9% N, a sum of O and N of greater than or equal to 22.3% and a contact angle of at least about 13.9 degrees, lacking a feeder cell layer and lacking an adlayer, comprising the steps of:
A surface that is part of a vessel or matrix intended for use in cell culture or analysis, containing from at least about 0.9% N, a sum of O and N of greater than or equal to 22.3% and a contact angle of at least about 13.9 degrees, lacking a feeder cell layer and lacking an adlayer, wherein the surface allows the attachment and cultivation of cells.
