| Product Name | Recombinant Streptavidin |
| Catalog No. | IGM-HMM-0080 |
| Description | An engineered recombinant streptavidin core protein that forms a noncovalent homotetramer with strong biotin-binding capacity and lower nonspecific interactions than avidin. |
| Intended Use | Preparation of streptavidin magnetic beads or affinity media for capture of biotinylated nucleic acids and proteins, and conjugation with dyes, fluorophores or enzymes for immunoassay signal amplification. |
| Principle / Technology | Each tetramer can bind four biotin molecules. Directed sequence engineering improves stability and biotin-binding performance while maintaining low nonspecific binding. |
| Specificity | High-affinity binding to biotin and biotinylated biomolecules. |
| Components / Formulation | Recombinant streptavidin protein. |
| Storage Conditions | Store at -30 to -15°C. Long-term storage at 2-8°C is not recommended; sterile filtration is advised when refrigerated storage is required. |
| Shelf Life | 3 years when stored as directed. Avoid repeated freeze-thaw cycles. |
| Package Specifications | 1 mg; 10 mg; 100 mg; 500 mg. Custom package sizes are available. |
| Product Form | Recombinant tetrameric protein. |
| Key Features | High biotin-binding capacity; strong stability; low nonspecific binding; broad labeling and immobilization compatibility. |
| Source / Origin | Engineered recombinant streptavidin core sequence. |
| Shipping Conditions | Ship at 0°C or below. |
| Compatibility | Magnetic beads, chromatography matrices, fluorescent labels, enzyme labels and immunoassay platforms. |
| Application Notes / Precautions | Avoid repeated freeze-thaw cycles. Optimize conjugation conditions for the selected carrier or reporter molecule. |
For research use only, not for clinical use.
