ABSTRACT A whitewater dispersant system containing a cationic surfactant and a cationic polyacrylamide. The viscosity modifier of the present invention may include amounts varying from 0 to 90% of a nonionic cellulosic viscosity modifier. The resulting whitewater is particularly effective in dispersing glass fibers in a slurry which is used to form a glass mat.

Model cationic flocculants from the Mannich reaction
14 C‐Labeled cationic derivatives of polyacrylamide were prepared by the reaction of polyacrylamide with 14 C‐labeled formaldehyde and dimethylamine hydrochloride. The resulting Mannich base was reacted with dimethyl sulfate. Both reactions produced a yield of about 50% and the final product was a substituted polyacrylamide with tertiary and quaternary amine groups.

- Why is polyacrylamide better than agarose?
- The pores formed in polyacrylamide are smaller than those of agarose, used for agarose gel electrophoresis. This makes it more suitable for the separation of proteins over large polynucleotide DNA or RNA fragments and allows the separation of relatively small proteins.
- Why are agarose and polyacrylamide gels used?
- The fundamental principle behind the use of agarose and polyacrylamide gels is size-based separation. In agarose gels, larger DNA fragments move more slowly through the matrix due to physical hindrance, whereas smaller fragments navigate the pores more easily.
- How much Agarose is used in a DNA gel?
- Most agarose gels are made with between 0.7 % (good separation or resolution of large 5–10 kb DNA fragments) and 2 % (good resolution for small 0.2–1 kb fragments) agarose dissolved in electrophoresis buffer. Up to 3 % can be used for separating very tiny fragments but a vertical polyacrylamide gel is more appropriate in this case.
- What is polyacrylamide gel electrophoresis?
- Different separation media and mechanisms allow subsets of these molecules to be separated more effectively by exploiting their physical characteristics. For proteins in particular, polyacrylamide gel electrophoresis (PAGE) is often the technique of choice. What is polyacrylamide gel electrophoresis and what is protein electrophoresis?
