Octyl glucoside (n-octyl-β-D-glucoside) is a detergent frequently used to solubilise integral membrane proteins for studies in biochemistry. Like Genapol X-100 and Triton X-100, it is a nonphysiological amphiphile that makes lipid bilayers less "stiff".[1]
It has become one of the most important detergents for purification of membrane proteins because it generally does not denature the protein and can readily be removed from final protein extracts.[2] Above its critical micelle concentration of 0.7%, it was noted as the best detergent for improving selectivity of immunoprecipitation of phosphotyrosine modified proteins.[3] This detergent has also been shown to rapidly inactivate infective HIV at concentrations above its CMC, about 0.7% (w/v)[4]
The compound gained popularity with researchers following the publication of an improved synthesis in 1978.[5][6] However, in 1990 the cost remained prohibitive for large-scale protein isolation.[7]
Octyl glucoside has been proposed as a conditioning agent to prevent microbial colonization of contact lenses, due to its ability to lower the hydrophobicity of contact lenses and prevent adhesion of Staphylococcus epidermidis and Pseudomonas aeruginosa.[8]
