sulfo-sanpah (sulfosuccinimidyl 6-(4′-azido-2

thermo scientific pierce sulfo-sanpah is a hetero-bifunctional crosslinker that contains an amine-reactive n-hydroxysuccinimide (nhs) ester and a photoactivatable nitrophenyl azide. nhs esters react efficiently with primary amino groups (-nh2) in ph 7–9 buffers to form stable amide bonds.

polyacrylamide hydrogels for cell mechanics: steps toward

the heterobifunctional photoreactive reagent sulfo‐sanpah. when the nitrophenyl azide reactive group is exposed to uv light (320–350 nm), it forms a nitrene group that can react nonspecifically with polyacrylamide.

effects of polyacrylamide of polyacrylamide (paa,to avoid the use of unstable chemicals such as reactive esters and expensive photoreactive agents such as sulfo-sanpah for the surface functionalization of pam hydrogels, a novel paa hydrogel called hydroxy-polyacrylamide (hydroxypam) has been suggested.

a novel method to make polyacrylamide gels with mechanical

prepare 5 mm sulfo-sanpah in 25% dmso and 75% 50 mm hepes ph 8.2 (first dissolve sulfo-sanpah in dmso, then add hepes in milliq water). a minimum of 80 µl 5 mm sulfo-sanpah solution per 18-mm diameter gel is needed.

Does Kemira produce cationic dry powder flocculants / polyacrylamides?
Kemira produces a full range of cationic dry powder flocculants / polyacrylamides (CDPAM) in a range of molecular weights. We also offer a full range of cationic inverse emulsion (CEPAM) flocculants of different cationic charge densities and molecular weight variants.
What is nonionic powder flocculants / polyacrylamides (ndpam)?
Nonionic powder flocculants can be produced with very high molecular weights, giving it the capability to form large, rapid-settling, good-compacting flocs. We produce nonionic powder flocculants / polyacrylamides (NDPAM) in a standard range plus in high and low molecular weights.
What are the types of industrial polyacrylamides?
The types of flocculants, in other words industrial polyacrylamides, are cationic, anionic or nonionic polyacrylamides. Kemira’s polyacrylamides of wide range of charge and molecular weight are sold in dry powder or emulsion format and have excellent performance.
What is cationic polyacrylamide used for?
Cationic polyacrylamides are used, among other things, for the dewatering of sludge from biological treatment processes. Typically, the higher the share of biological sludge in the total amount of sludge, the higher the cationic charge density required in the polymer.
