非イオン界面活性剤は他のものより変性作用が少ないため、タンパク質間相互作用を保持しながら膜タンパク質および脂質を可溶化するのに有用である。非イオン界面活性剤には、ポリエーテル系非イオン界面活性剤、ポリヒドロキシル系非イオン界面活性剤およびバイオ界面活性剤がある。非イオン界面活性剤としては、アルコールエトキシラート、アルキルフェノールエトキシラート、フェノールエトキシラート、アミドエトキシラート、グリセリドエトキシラート、脂肪酸エトキシラートおよび脂肪アミンエトキシラートが挙げられる。本明細書に開示される非イオン界面活性剤は、一般式Ｈ（ＯＣＨ_２ＣＨ_２）_ｘＯＣ_６Ｈ_４Ｒ^１、Ｈ（ＯＣＨ_２ＣＨ_２）_ｘＯＲ^２またはＨ（ＯＣＨ_２ＣＨ_２）_ｘＯＣ（Ｏ）Ｒ^２を有し得るものであり、式中、ｘはアルキルフェノールおよび／または脂肪アルコールもしくは脂肪酸に付加したエチレンオキシドのモル数を表し、Ｒ^１は長鎖アルキル基を表し、Ｒ^２は長鎖脂肪族基を表す。この実施形態の諸態様では、Ｒ^１がＣ_７〜Ｃ_１０アルキル基であり、かつ／またはＲ^２がＣ_１２〜Ｃ_２０脂肪族基である。その他の有用な非イオン界面活性剤としては、特に限定されないが、ＳＴＥＰＯＳＯＬ（登録商標）ＭＥＴ−１０Ｕ、メタセシスによって得られ不飽和短鎖アミドである非イオン界面活性剤を含めたバイオ非イオン界面活性剤が挙げられる。このようなバイオ界面活性剤は合成分子ではなく、植物などの有機物に由来する非イオン性のバイオ界面活性剤である。 Nonionic surfactants have less denaturing action than others and are useful for solubilizing membrane proteins and lipids while retaining protein-protein interactions. Nonionic surfactants include polyether-based nonionic surfactants, polyhydroxyl-based nonionic surfactants, and biosurfactants. Nonionic surfactants include alcohol ethoxylates, alkylphenol ethoxylates, phenol ethoxylates, amido ethoxylates, glyceride ethoxylates, fatty acid ethoxylates and fatty amine ethoxylates. The nonionic surfactants disclosed herein have the general formula H (OCH ₂ CH ₂ ) _x OC ₆ H ₄ R ¹ , H (OCH ₂ CH ₂ ) _x OR ² or H (OCH ₂ CH ₂ ) _x OC (O) R ² where x represents the number of moles of ethylene oxide added to the alkylphenol and / or fatty alcohol or fatty acid, R ¹ represents a long chain alkyl group, and R ² represents Represents a long chain aliphatic group. In aspects of this embodiment, R ¹ is a C ₇ -C ₁₀ alkyl group and / or R ² is a C ₁₂ -C ₂₀ aliphatic group. Other useful nonionic surfactants include, but are not limited to, STEPOLSOL® MET-10U, bio nonionic surfactants including nonionic surfactants that are unsaturated short chain amides obtained by metathesis Agents. Such a biosurfactant is not a synthetic molecule but a nonionic biosurfactant derived from organic substances such as plants.
