背景资料:
Streptavidin is a tetrameric protein secreted by Streptomyces avidinStreptavidin although stable 4℃ for 4 weeks， should be stored desiccated below -18℃. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please prevent freeze-thaw cycles. 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 4℃ for 4 weeks， should be stored desiccated below -18℃. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please prevent freeze-thaw cycles. Recombinant fused to N-terminal His-Tag produced in E.Coli is a single， non-glycosylated polypeptide chain containing 167 amino acids and having a molecular mass of 17 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
Covalent Coupling of DNA Oligonucleotides and Streptavidin
Semisynthetic DNA-protein conjugates are synthesized by covalent coupling of thiol-modified DNA oligonucleotides and streptavidin. The resulting conjugates have a binding capacity for four equivalents of biotin and one nucleic acid
