Streptavidin

  • Overview

    Streptavidin is a tetrameric protein purified from Streptomyces sp. that binds very tightly to the vitamin biotin with a Kd of ~ 10-14 mol/l. The high affinity recognition of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits.

Q&As (7)

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.
