    2020-1-15 · The molecular weight was reduced from 1.6 × 10 6 to 6.45–7.42 × 10 5 Da for the low molecular weight PAM, while the high molecular weight PAM declined from 2.2 × 10 7 to 3.76–5.87 × 10 6 Da. The results showed that the amino hydrolysis of low molecular weight PAM is easier than that of the high molecular weight one, while the cleavage of its carbon chain is still difficult.

  • Polymer 101: Fundamentals of Flocculation

    2016-8-9 · The high resolutionand high capacity of polyacrylamide gels makes them the method of choicefor the purification of oligonucleotides. Urea disrupts hydrogen bondingbetween bases and thus allows oligonucleotides to be resolved almost exclusivelyon the basis of molecular weight as opposed to secondary structure.
