Recombinant Streptavidin
英文简称:
Streptavidin
中文名称:
重组链霉亲和素
背景资料:
Streptavidin is a tetrameric protein secreted by Streptomyces avidinStreptavidin although stable 20℃ for 1 week， should be stored at 4℃. which binds firmly to biotin. Streptavidin is widely used in molecular biology through its unique high a大肠杆菌中重组表达inity for the vitamin biotin. The dissociation constant （Kd） of the biotin-streptavidin complex is about ~10-15 mol/L. The strong a大肠杆菌中重组表达inity recognition of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits. The streptavidin/biotin system has one of the biest frStreptavidin Streptomyces AvidinStreptavidin although stable 20℃ for 1 week， should be stored at 4℃. Recombinant produced in E.Coli is a single， non-glycosylated polypeptide chain having a molecular mass of 18 kDa. energies of association of yet observed for noncovalent binding of a protein and small ligand in aqueous solution （K_assoc = 10**14）. The complexes are also extremely stable over a wide range of temperature and pH.

文献和实验[ 实验目的 ] 通过本实验学习 PCR 反应的基本原理与实验技术。 通过本实验学习重组质粒的检测技术。 [ 基本原理 ] 聚合酶链反应（ polymerase chain reaction ， PCR ）是体外酶促合成特异 DNA 片段的一种技术。在待扩增的 DNA 片段两侧和与其两侧互补的两个寡核苷酸引物，经变性、退火和延伸若干个循环后， DNA 扩增 2 n 倍。 PCR 进行的基本条件是： （ 1 ）以 DNA 为模板（在 RT － PCR 中模板是 RNA ）； （ 2 ）以寡核苷酸
Colloidal Gold/Streptavidin Methods
. This nonspecific binding has been attributed both to its high isoelectric point (PI = 10) and to the fact that the protein is glycosylated (3 , 4 ). Because of the problem of nonspecific binding of avidin, streptavidin has largely replaced avidin
Smart Polymer-Streptavidin Conjugates
The conjugation of stimuli-responsive, or “smart,” polymers to streptavidin is described. The polymer is synthesized with a thiol-reactive end-group, which is used to end-graft the polymer to cysteine or lysine side-chains
