Polyacrylamide (MW 10,000) - Polysciences

Polyacrylamide (PAM, Mw 10,000) is a low molecular weight nonionic water-soluble polymer used as an additive in CMP slurries, various printing applicatons, and as a flocculant in water treatment. 50% solution in water (packaging size denotes weight of solution).

Introduction to Polyacrylamide Gels | LSR | Bio-Rad

Polyacrylamide gels are characterized by two parameters: total monomer concentration (%T, in g/100 ml) and weight percentage of crosslinker (%C). By varying these two parameters, the pore size of the gel can be optimized to yield the best separation and resolution for the proteins of interest.

Polyacrylamide: A Review of the Use, Effectiveness,

High molecular weight PAMs tend to be more effective than low molecular weight PAMs. A study by Levy and Agassi (1995) showed that the 20 Mg mol-1 PAM performed better than the 200 kg mol-1 PAM in reducing soil loss and maintaining infiltration rates. Current research using PAMs as soil conditioners focuses on high molecular weight (10-20

Spontaneous and Inductive Thickenings of Lamellar Crystal

Crystalline macromolecules form folded-chain lamellar and metastable crystals. Annealing at a temperature below melting point results in a thickening of the metastable crystals to construct more st...

Polyacrylamide

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.

Electrophoresis Reagents - Alfa Aesar

Gel electrophoresis is used to separate biological macromolecules. When an electric current is applied to these molecules in a gel matrix they can be separated based on their sizes and net charges. Proteins are typically separated with polyacrylamide as the gel matrix. Separation is affected by the percentage of acrylamide in the gel matrix.

(IUCr) Smart crystallization

An alternative approach might have been to suspend them in a solvent, but this brings its own problems. Instead, the team’s current work has now developed a less viscous - close to that of low molecular weight polyethylene glycol (PEG) - generic MIP that can trap and nucleate different proteins with similar hydrodynamic radii.

Enzymes as useful tools for environmental purposes

Enzyme activity in pollutant transformation can be improved by low-molecular weight additives. • Immobilized enzymes are suitable for continuous processes for long-term and operational stability. • Enzymes could act as biosensors in environmental pollution monitoring. • Enzymes could act as bioindicators of water or soil quality and health.

Processes of carbonate precipitation in modern microbial

In addition, half of the 14 C–HCO 3 − uptake by cyanobacteria was excreted as low molecular-weight organic carbon (LMWOC; Decho et al., 2005). This LMWOC was rapidly consumed by aerobic and anaerobic heterotrophic bacteria, with the highest microbial activity associated with the surface layer, where CaCO 3 precipitates.
