Polyacrylamide (MW 10,000) - Polysciences, Inc.
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).
Several studies have shown that high molecular weight anionic polymers (e.g. polyacrylamide) are commonly used in the settling of negatively charged kaolinite , , , . In this case, the polymer bridging mechanism is of primary importance, whereas charge neutralization will be of secondary or little importance . The use of high molecular weight

Observations on Molecular Weight Determinations on Polyacrylamide Gel* (Received for publication, May 5,1969) A. K. DUNKERI AND ROLAND R. RUECKERT~ From the Biophysics Laboratory and Department of Biochemistry, University of Wisconsin, Madison, Wisconsin 53706 SUMMARY 1. A simple internal calibration technique was used to
Polyacrylamide degradation and its implications
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction
StpNRX1 has a predicted molecular weight of 126.5 kDa, which is in disagreement with the molecular weight of 141 kDa determined by Western blotting (fig. 4C). In humans, the Caspr1 protein is glycosylated ( Bonnon et al. 2003 ); we therefore examined whether StpNRX1 also exhibits posttranslational N-linked glycosylation that contributes to the

The protomer is formed by three α-chains, usually two α-1 chains and one α-2 chain, whose primary structures indicate an apparent molecular weight of ∼185 and 170 kDa, respectively (Hostikka and Tryggvason 1987; Soininen et al. 1987). Further, two protomers of type IV collagen associate via NC1 trimers to give an NC1 hexamer, and finally

The nucleotidyl cyclase toxin ExoY is one of the virulence factors injected by the Pseudomonas aeruginosa type III secretion system into host cells. Inside cells, it is activated by an unknown
Protein–protein interactions: switch from classical
Following the sequencing of the human genome and many other organisms, research on protein-coding genes and their functions (functional genomics) has intensified. Subsequently, with the observation that proteins are indeed the molecular effectors of most cellular processes, the discipline of proteomics was born. Clearly, proteins do not function as single entities but rather as a dynamic
The migration of protein molecular weight standards (in kilodaltons) is shown at the left of the figure. Differential Distribution of IL-15Rα, IL-2Rα, -β, and -γ RNA A variety of cell lines and tissues was examined for the expression of IL-15Rα mRNA, as well as for IL-2Rα, -β and -γ mRNA, to assess the relative potential of each cell
