• 介紹：
  SDS說(shuō)明：生化研究，用于從蛋白質(zhì)中分離核酸，從宿主細(xì)胞中脫落某些病毒；蛋白電泳試劑，也可用于質(zhì)粒提取
  SDS生物學(xué)應(yīng)用：
  (1)SDS是陰離子表面活性劑常用于蛋白質(zhì)和類(lèi)脂類(lèi)的電泳分離。當(dāng)其與蛋白質(zhì)混合,質(zhì)量比達(dá)到1.4:1時(shí)，SDS能破壞蛋白質(zhì)分子間以及其他物質(zhì)分子間的非共價(jià)鍵使蛋白質(zhì)的構(gòu)象發(fā)生變化繼而使蛋白質(zhì)變性解離成單一亞基，從而降低或消除了各種蛋白質(zhì)分子間的天然電荷差異。電泳常用10%的SDS作為儲(chǔ)備液。
  (2)SDS可以迅速破壞組織結(jié)構(gòu)，抑制RNase和脫氧核糖核苷酶（DNase）活性，所以SDS也是核酸純化試劑的關(guān)鍵組分。通常使用10%或者20%的SDS儲(chǔ)備液，SDS的工作濃度是0.1-0.5%。
  SDS貯存條件：密封陰涼干燥保存；
  SDS毒性：低毒，大鼠經(jīng)口半數(shù)致死量為1288mg/kg。有刺激性。
