11. These substances include silicone oil and polyacrylamide gel. 12. This problem is resolved by developing polyacrylamide gels that contain larger average pore size. 13. It is a nonresorbable polyacrylamide hydrogel made of cross-linked polyacrylamide and water. 14. It is a nonresorbable polyacrylamide hydrogel made of cross-linked polyacrylamide and water. 15. Subsequent publications reported that polyacrylamide gels could be successfully destained using an acetic acid solution. 16. Polonies can be generated using several techniques that include solid-phase PCR in polyacrylamide gels. 17. The DNA is then run on a polyacrylamide gel and visualised overnight with a phosphoimaging screen. 18. This product is electrophoresed in a polyacrylamide gel, and the DNA is visualized following staining. 19. See the " Chain termination method " page for an example of a polyacrylamide DNA sequencing gel. 20. Another common use of polyacrylamide and its derivatives is in subsurface applications such as Enhanced Oil Recovery.
