产品介绍
分子量: 54kDa (tetramer), 13.5kDa (monomer) 物理外观: Lyophilized 储存缓冲液: 5mM PBS, pH 7.4 复溶(Reconstitution): Reconstitute in sterile distilled water. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C 产品描述: 链霉亲和素(Streptavidin,SA)是阿维丁链霉菌(Streptomyces avidinii)在生长过程中分泌的一种同型四聚体蛋白。同亲和素一样,一摩尔的链霉亲和素可以结合四摩尔的生物素,与生物素具有很高的亲和力。由于链霉亲和素不含糖基且等电点接近于中性,因此链霉亲和素在检测应用中具有比亲和素更低的非特异性结合水平。 该制品已被广泛应用于多种生物技术领域,诸如:包被免疫检测用微孔板,制备 SA 偶联酶制剂,SA 偶联荧光素、SA 偶联磁珠等,进而参与酶联免疫吸附和酶催化放大实验,免疫组化化学、生物分子纯化、生物传感器、生物纳米微球、预靶向制药研究和生物芯片被料等。 重组核心链霉亲和素与天然链霉亲和素相比,去除与活性无关的序列,仅保留与活性有关的核心序列,稳定性、溶解性等方面均优于天然链霉亲和素,并且在C 端添加了半胱氨酸,可以定向与载体共价键合。(该重组链霉亲和素 pI:6.04) 阿拉丁链霉亲和素系列产品: 货号
