Poly(ethylene glycol) 4-nonylphenyl 3-sulfopropyl ether, potassium salt

Poly(ethylene glycol) 4-nonylphenyl 3-sulfopropyl ether potassium salt can be used as an anionic surfactant in the fabrication of hierarchical β-Ni(OH)₂ microspheres and nickel oxide hollow spheres for supercapacitor applications.
Poly(ethylene glycol) 4-nonylphenyl 3-sulfopropyl ether potassium salt was also demonstrated to be effective for protecting thermostable DNA polymerase during amplification reactions conducted at a temperature ranging from about 40° C to greater than 100° C.
DNA polymerases, such as Taq, do become inactive over time at the high temperatures utilized in thermal cycling reactions such as polymerase chain reaction (PCR). It has been discovered that thermostable DNA polymerases could be protected from such heat inactivation by contacting the polymerase with poly(ethylene glycol) 4-nonylphenyl 3-sulfopropyl ether potassium salt during a thermal cycling process, and improve the specificity of amplification.
