蛋白質萃取系列-Detergen洗滌劑商品
![]()
Detergents洗滌劑是包含polar極性和hydrophobic regions疏水區域的amphipathic molecules兩親性分子,其允許它們作為solubilizing agents增溶劑。洗滌劑可以分為幾個主要類別:離子洗滌劑;非離子洗滌劑和兩性離子洗滌劑。離子洗滌劑具有帶電頭基(陰離子或陽離子),可用於SDS-PAGE期間細胞的完全破壞和蛋白質變性分離。這些可以包括陰離子洗滌劑如SDS,陽離子洗滌劑如CTAP和陰離子膽汁鹽如deoxycholate脫氧膽酸鹽。通常稱為非變性洗滌劑的非離子洗滌劑可用於膜蛋白的溶解,因為它們能夠破壞脂質 – 脂質和脂質 – 蛋白質的相互作用,但具有有限的破壞蛋白質 – 蛋白質相互作用的能力。它們包括低CMC洗滌劑如Triton X-100和不能透析的NP-40替代物,不帶電的膽汁鹽,如Big Chap(可透析)和非常透析的(CMC〜25mM)烷基葡糖苷如辛基吡喃葡萄糖苷。兩性離子洗滌劑保護蛋白質的天然狀態而不改變蛋白質分子的天然電荷。除了溶解性質外,兩性離子洗滌劑對於等電聚焦和2D電泳非常有用。許多合成的兩性離子洗滌劑被稱為磺基甜菜鹼。磺基甜菜鹼在廣泛的pH範圍內保持其兩性離子特徵,並廣泛用於2D凝膠電泳。非洗滌劑磺基甜菜鹼(NDSB)是一類兩性離子化合物,具有類似於兩性離子洗滌劑的親水基團,但具有更短的疏水鏈,不能聚集形成膠束。雖然不被認為是洗滌劑,但是當與洗滌劑一起使用時,NDSB可以提高膜,核和細胞骨架蛋白的產量。結合磺基甜菜鹼基團的電荷中和的短疏水基團導致獲得更高的膜蛋白產率。 NDSB還有助於減少聚集並幫助重折疊包涵體和細菌表達系統中發現的蛋白質。 NDSB在寬pH範圍內是兩性離子的,通過透析容易去除,並且在近紫外範圍內不會顯著吸收。
