NP-40 (also known as Tergitol-type NP-40 and nonyl phenoxypolyethoxylethanol [1]) is a commercially available detergent with CAS Registry Number 9016-45-9. NP-40 is an ethoxylated nonylphenol for non-ionic surfactants and can act as emulsifier and demulsifier agent.
Nonidet P-40 is a nonionic, non-denaturing detergent. Its official IUPAC name is octylphenoxypolyethoxyethanol. Nonidet P-40 is sometimes abbreviated as NP-40, but should not be confused with a different detergent by the same name NP-40 , nonylphenoxypolyethoxyethanol of the Tergitol NP series of Dow Chemicals.
Radioimmunoprecipitation assay buffer (RIPA buffer) is a lysis buffer used to lyse cells and tissue for the radio immunoprecipitation assay (RIPA). [1] [2] This buffer is more denaturing than NP-40 or Triton X-100 because it contains the ionic detergents SDS and sodium deoxycholate as active constituents and is particularly useful for disruption of nuclear membranes in the preparation of ...
The solubilizing agent is NP-40, which can be replaced by other detergents at different concentrations. Since NP-40 is a nonionic detergent, this lysis buffer has a milder effect than RIPA buffer. It can be used when protein functions are to be retained with minimal disruption. [9] Recipe: [9] 150 mM NaCl; 1.0% Nonidet P-40 or Triton X-100; 50 ...

The single NA-40 built flew first at the end of January 1939. It went through several modifications to correct problems. These improvements included fitting 1,600 hp (1,193 kW) Wright R-2600 "Twin Cyclone" radial engines, in March 1939, which solved the lack of power. [1] In March 1939, North American delivered the substantially redesigned and ...
A wide variety of neptunium sulfide compounds have been characterized, including the pure sulfide compounds NpS, NpS 3, Np 2 S 5, Np 3 S 5, Np 2 S 3, and Np 3 S 4. Of these, Np 2 S 3 , prepared by reacting NpO 2 with hydrogen sulfide and carbon disulfide at around 1000 °C, is the most well-studied and three allotropic forms are known.
