N,N-dimethyl-6-propionyl-2-naphthylamine (prodan) has both an electron-donor and an electron-acceptor substituent, resulting in a large excited-state dipole moment and extensive solvent polarity-dependent fluorescence shifts. When prodan is incorporated into membranes, their fluorescence spectra are sensitive to the physical state of the surrounding phospholipids. In membranes, prodan appears to localize at the surface, although Fourier transform infrared measurements indicate some degree of penetration into the lipid interior. Excited-state relaxation of prodan is sensitive to the nature of the linkage between phospholipid hydrocarbon tails and the glycerol backbone. Tubulin and its hydrophobic surfaces have been probed with the enviroment-sensitive probes prodan. Prodan is also used for the generation of peroxy-oxalate chemiluminescence with H2O2.

SOLVENT HPLC MOBILE PHASE B 60% 4L

Supplier: Thermo Scientific

Adding a syringe filtration step prior to injection not only helps to ensure more consistent and reliable results; it also helps protect delicate instruments and prolongs column life.

Supplier: Cytiva

For prefiltering heavily contaminated aqueous or solvent based samples.

Supplier: Corning

Syringe filters are available with a choice of membrane type: Polyethersulfone (PES) for low protein binding and faster flow rates; surfactant-free cellulose acetate (SFCA), with or without prefilter, for lowest protein binding; Polytetrafluoroethylene (PTFE) for chemical resistance; regenerated cellulose (RC) – the best choice for DMSO compatibility; and nylon (NY) which is hydrophilic, surfactant-free and lowest extractable.

O.D. x Length 1.1" x 0.8", Porosity 2 micron, Fits Tubing Size 1/8" O.D. The inlet/sparge filter combines an inlet filter with a sparger in a single, convenient device. The all PEEK construction is ideal for virtually all mobile phases. The special design prevents sparging bubbles from entering the mobile phase stream while allowing the pump to draw all but a few milliliters of solvent from the reservoir. The inlet/sparge filter is supplied with 2 micronm porosity frits and connections for 1/8" O.D. tubing.
