Streptavidin

The value of pre-activated magnetic beads does not lie merely in providing a magnetically separable solid support, but in integrating surface reaction sites, interfacial hydrophilicity, and downstream capture performance into a single material platform in advance. For target enrichment from ...

Eluting biotinylated proteins and DNA from streptavidin beads usually requires relatively harsh conditions, such as enzymatic digestion, extreme pH, organic solvents, or heating in the presence of excess biotin. The most appropriate elution strategy will depend on the properties of your ...

Streptavidin is a bacterial protein that binds the small molecule biotin with exceptionally high affinity. The streptavidin–biotin pair represents one of the strongest noncovalent interactions known. Streptavidin agarose beads take advantage of this interaction as a solid-phase platform to ...

The streptavidin–biotin system has extremely high affinity and is one of the most commonly used tool pairs for immobilization, capture, and elution of nucleic acids and proteins.

The streptavidin–biotin system is one of the most widely used high-affinity ligand–receptor pairs in biochemistry and molecular biology.

Streptavidin is a homotetramer (each subunit contains one biotin-binding site), allowing up to four ligands per tetramer in theory.

Immunoprecipitation of natural proteins is a classic method for studying natural protein interactions, which relies on the specific binding between antibodies and proteins (antigens). This technique can be used to qualitatively detect proteins, determine the physiological role of proteins in ...
