Streptavidin agarose resin
Cat.No. : | Streptavidin-001A |
Product Overview : | Streptavidin Sepharose is a magnetic bead for simple and efficient enrichment of target proteins by immunoprecipitation and purification of biotinylated biomolecules. Streptavidin Mag Sepharose utilizes the strong interaction between biotin and streptavidin ligand, which is immobilized on magnetic beads. Magnetic beads simplify sample handling in small-scale purifications. |

Q&As (7)
Ask a questionStreptavidin formulations often include shortened variants (core streptavidin proteins) with shortened N and C termini compared to natural streptavidin. These variants offer improved characteristics in terms of homogeneity, solubility, resistance to protein hydrolysis, and accessibility of the biotin-binding pocket.
Streptavidin is a 55kDa tetrameric protein secreted by Streptomyces avidinii, known for its strong binding affinity with biotin.
Streptavidin tightly binds to biotin (sc-204706).
The dissociation constant (Kd) for the Biotin-Streptavidin complex is approximately ~10^15M, indicating an exceptionally strong binding affinity.
The Streptavidin/Biotin system exhibits one of the largest observed binding free energies, making it suitable for non-covalent binding of proteins and small ligands in aqueous solutions. The complex is also highly stable over a broad range of temperature and pH values.
Streptavidin is produced by Streptomyces avidinii.
Streptavidin is widely used in molecular biology due to its unique high affinity for biotin, making it a valuable tool for various applications.
