产品介绍
分子量:55.2kDa (tetramer), 13.8kDa (monomer) 储存缓冲液: Lyophilized from 5mM PPB, Trehalose, pH 7.4 复溶(Reconstitution): Reconstitute in sterile distilled water. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions. 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 SA 不含糖基且等电点接近于中性,因此 SA 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4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,稳定性、溶解性等方面均优于天然链霉亲和素。并对序列做了修饰,增加了氨基的含量,提高了与配体或者磁珠以氨基方式偶联的效率(该产品 pI:8.93)。 阿拉丁链霉亲和素系列产品: 货号
