Streptavidin magnetic beads provide optimized biotin binding, superior magnetic responsiveness, and enhanced separation efficiency. Designed for molecular biology and diagnostic applications, they ensure precise biomolecule capture, extended durability, and high adaptability.
Product Overview
Streptavidin Magnetic Beads are magnetic nanoparticles based on iron oxide (Fe₃O₄) cores, with streptavidin functionalized on the surface. The strong affinity between streptavidin and biotin makes these beads highly suitable for bio-molecule capture, detection, and separation. Their magnetic properties allow for easy manipulation and isolation, making them valuable in a variety of biomedical, molecular biology, and imaging applications.
Key Features
- High Biocompatibility: The surface-modified Fe₃O₄ ensures excellent biocompatibility, making the beads suitable for both in vitro and in vivo applications.
- High Sensitivity: The strong streptavidin-biotin interaction provides high sensitivity in detection applications, particularly effective for detecting low-concentration target molecules.
- High Specificity: The streptavidin-biotin system has exceptional specificity, enabling precise capture of biotin-labeled target molecules.
Applications
- Biosensing: The high affinity between streptavidin and biotin makes these magnetic beads ideal for use in biosensors for detecting molecular interactions.
- Magnetic Resonance Imaging (MRI): Due to their magnetic properties, these beads can serve as MRI contrast agents, improving image contrast and resolution.
- Cell Separation and Enrichment: With their magnetic nature, these beads enable easy isolation and enrichment of specific cell types from complex samples, making them widely used in cell analysis and immunoselection.
