Diffusion in polyacrylamide gels
Polymer, 1981Abstract Using a novel sorption technique, the diffusion of some series of solutes in polyacrylamide gels has been investigated with regard to: (a) molecular size of solute; (b) concentration of solute and gel polymer; and (c) temperature. The approach used also yields the partition coefficient pertaining to sorption equilibrium. The ratio, D D

Degradation of Polyacrylamide: A Review
Advanced Materials Research, 2013Water-soluble polyacrylamide is commercially available in different domains of industry, such as water purified, paper making, pharmacy, agriculture and oil exploitation. Especially polyacrylamide is used for polymer displacement, which can enhance oil recovery through increasing the sweeping efficiency.

Visualization of proelastase in polyacrylamide gels
Analytical Biochemistry, 1977Abstract Our attempt to identify as many pancreatic enzymes as possible after their electrophoretic separation on polyacrylamide gels led us to search for a specific and simple method to localize proelastase. Esterolytic activity of elastase or elastase-like enzymes has been visualized in polyacrylamide gels (1,2) and cellulose acetate plates (3) by

An electron microscopical study of Polyacrylamide
Journal of the Royal Microscopical Society, 1967SYNOPSISThe stages leading to the depositing of individual molecules of Polyacrylamide by spray technique have been studied electron microscopically. The number and weight average molecular weights of a high‐molecular‐weight fraction of Polyacrylamide were found to be 2.33 ± 0.23 × 106 and 2.59 ± 0.26 × 106 respectively, while the intrinsic viscosity ...

Oriented macroporous polyacrylamide gels
ELECTROPHORESIS, 1997AbstractMacroporous gels with huge cavities and partition walls result from controlled microsyneresis during gelation. In this report we show that the microsyneresis process can be further controlled: it is possible to orient the partition walls of macropores by the use of an electric field throughout polymerization.

Polyacrylamide adsorption by cellulose
Colloid and Polymer Science, 1977Polyacrylamide adsorption by sulphite bleached, sulphite unbleached and monocarboxyl-cellulose was investigated. The kinetics of the adsorption process was studied, the reaction order was established and the velocity constants, the velocity temperature coefficients and the activation energies were determined.

What place for polyacrylamide in proteomics?
Trends in Biotechnology, 2001Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) continues to deliver high quality protein resolution and dynamic range for the proteomics researcher. To remain as the preferred method for protein separation and characterization, several key steps need to be implemented to ensure quality sample preparation and speed of analysis.

Fluorometric scanning of polyacrylamide gels
Analytical Biochemistry, 1969Abstract A gel scanning technique that measures the quench of N-allyl-DANSA fluorescence by amido schwarz stained protein bands had the potential capability of about fifty times the sensitivity of absorption densitometric techniques. The preparation of the fluorescent polyacrylamide gels was straightforward and their electrophoretic resolving and ...
