3 Function description
Streptavidin is a 60kDa egg purified from the bacterial avidin Streptomyces
White matter. Streptavidin homotetramer has a very high affinity for biotin (ie vitamin B7). Biotin and
The binding of streptavidin is one of the strongest non-covalent interactions known in nature, and its dissociation constant (Kd) is approximately
It is 1014 mol/L[1]. Because the streptavidin-biotin complex has an effect on organic solvents, denaturants (such as guanidine hydrochloride), washing
Detergents (such as SDS and Triton), proteolytic enzymes and extreme temperature and pH have good tolerance, so the chain affinity
Hesu is widely used in molecular biology and bio-nanotechnology.
The DiscoverMagTM-Streptavidin Magnetic Beads prepared by our company have non-specific adsorption
Small, easy to disperse and recover the magnetic beads, high biotin binding capacity, etc., is an ideal capture biotinylated
Affinity material for protein, nucleic acid or polypeptide.
