Ammonium persulfate for molecular biology, suitable for electrophoresis, ≥98% | 7727-54-0
Ammonium persulfate (APS) is a widely used reagent in biochemistry and molecular biology for the preparation of polyacrylamide gels. APS forms oxygen free radicals in aqueous solution by a base-catalyzed mechanism. The bases, most commonly used
The CAPAM showed better flocculation performance than cationic polyacrylamide and polyaluminum sulfate at a fixed concentration of 0.3% in waste drilling fluid and tended to perform well in
Shift of bacterial community structure in two Thai soil series affected by silver nanoparticles using ARISA
In this study we examined the influence of silver nanoparticles (SNP) on the bacterial community and microbial processes in two soils from Thailand, a Ayutthaya (Ay) and Kamphaengsaen soil series (Ks). Results of this analysis revealed that SNP
For gel filtration, 500 to 800 mg of type II peroxidase was dissolved in 5 to 10 ml of 0.15 M sodium chloride solution containing 50 m phosphate buffer (pH, 7.4) and loaded on a 50 x 2.5-cm polyacrylamide gel-agarose column (Ultrogel AcA 44, LKB

Polyacrylamide Gel Electrophoresis (PAGE) Acrylamide gels serve as a size-selective sieve during separation. As proteins move through a gel in response to an electric field, the smaller molecules travel more rapidly than larger proteins (see
The SDS- polyacrylamide gel electropherogram of extracted total seed proteins of 10 breeding lines in each of the 6 varieties investigated, revealed a pattern in which 12 polypeptide bands
MOPS
MOPS (3-(N-morpholino)propanesulfonic acid) is a buffer introduced by Good et al. in the 1960s. It is a structural analog to MES. Its chemical structure contains a morpholine ring.HEPES is a similar pH buffering compound that contains a
"Science sans conscience n'est que ruine de l'âme" dixit François Rabelais (1494-1553). A finder An unprecedented review, probably the best and most accomplished on
- Does cationic hydrophobically associating polyacrylamide have good salt resistance?
- Although it is generally believed that cationic hydrophobically associating polyacrylamide has good salt resistance [ 37, 38, 39 ], in this paper, due to the extremely low polymer concentration, the viscosity of the solution is still greatly reduced.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
- Which cationic polymer has the best flocculation efficiency?
- The PAmPTAC polymer had an optimal dose at 252 mg/g dry biomass. The difference in flocculation efficiency between two polymers is likely due to the differences in molecular weight. In the flocculation process by cationic polymers, charge neutralization of microalgal cells initiates floc formation.
