| abstract |
The present invention provides polyacrylamide hydrogels (especially polyacrylamide hydrogel arrays) made from prepolymers and polyacrylamide reactive polymers, as well as methods and compositions for preparing the polyacrylamide hydrogels or hydrogel arrays. The method advantageously provides greater control of polyacrylamide pore size and crosslink density, allowing, for instance, preparation of a polyacrylamide hydrogel appropriate for use with DNA. Furthermore, the methods and compositions can be employed in commercial processes. |
