The Journal of biological chemistry, 257(7), 3551-3554 (1982-04-10)
Solubilization of the ATPase of sarcoplasmic reticulum vesicles with the nonionic detergent dodecyl non-aoxyethylene alcohol (C12E9) resulted in a large (about 5-fold) increase in its Ca2+ ATPase activity. Measurements using a calcium ionophore suggest this activation was the result of

Talanta, 29(5), 397-400 (1982-05-01)
The fluorescence intensities of terbium, europium and samarium complexes with several beta-diketone derivatives in the absence and presence of tri-n-octylphosphine oxide (TOPO) in micellar solution of nona-oxyethylene dodecyl ether (BL-9EX) were examined. The spectrophotofluorimetric determination of terbium (1.5-1500 ng/ml) has
G Pappert et al.
Biochimica et biophysica acta, 730(1), 32-40 (1983-04-21)
Band 3 protein, the anion transport protein of the human erythrocyte membrane, was solubilized and purified in aqueous solutions of two nonionic detergents: Ammonyx-LO (dimethyl laurylamine oxide) and C12E9 (nonaethylene glycol lauryl ether). The state of association of the purified
