| abstract |
Polyamides comprising at least one hydrophilic C1-C10 hydrocarbyl substituent on an amide nitrogen atom, and methods for producing and using the same is provided. In particular, polyamides of formula (I) or (II) and methods for using the same for altering the ratio of charge/translational frictional drag of binding polymers to allow electrophoretic separation of polynucleotides or analogs thereof in a non-sieving liquid medium is provided, where a, q, L?1, P1, Q1, R, R1, R10 and R11¿ are those described herein. |
