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.

Ask a question
How does Streptavidin differ from natural streptavidin in its formulation? 01/23/2022

Streptavidin 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.

What is Streptavidin? 10/20/2021

Streptavidin is a 55kDa tetrameric protein secreted by Streptomyces avidinii, known for its strong binding affinity with biotin.

What is the binding partner of Streptavidin? 12/17/2020

Streptavidin tightly binds to biotin (sc-204706).

What is the dissociation constant (Kd) of the Biotin-Streptavidin complex? 01/22/2019

The dissociation constant (Kd) for the Biotin-Streptavidin complex is approximately ~10^15M, indicating an exceptionally strong binding affinity.

What are the key features of the Streptavidin/Biotin system? 03/18/2018

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.

What is the origin of Streptavidin? 03/05/2018

Streptavidin is produced by Streptomyces avidinii.

Why is Streptavidin widely used in molecular biology? 01/15/2017

Streptavidin is widely used in molecular biology due to its unique high affinity for biotin, making it a valuable tool for various applications.
