Avidin, Biotin, Streptavidin

Efficiently create detection reagents, study protein-protein interactions, and more with high-quality avidin, biotin, and streptavidin reagents from Rockland. Our comprehensive selection includes avidin, biotin, and streptavidin already conjugated to fluorochromes and enzymes, as well as individual reagents that can be conjugated in your own lab. The robust binding properties of these systems make them ideal for various applications such as Western blotting, ELISA, FLISA, IHC, IF, flow cytometry, ChIP, and protein-protein interactions.

  • High affinity binding: Avidin and streptavidin bind biotin with a dissociation constant (Kd) of approximately 10-15 M, ensuring strong and stable interactions.
  • High specificity: These systems are highly selective for biotin, ensuring minimal background binding and enhanced signal clarity.
  • Versatile applications: Suitable for a wide range of applications including immunoassays, purification, and labeling.
