Product Data | |
Description | Streptavidin protein, 5 mg |
Protein Source | S. avidinii |
Predicted MW | 53 kDa |
Purity | >95% pure (SDS-PAGE) |
Buffer | Presentation State: Purified State: Lyophilized Streptavidin from Streptomyces avidinii (Essentially salt free) Buffer System: PBS Preservative: 1% Mannitol Stabilizer: 1% Dextran |
Bioactivity | Biological: One unit will bind 1 µg of D-Biotin. Specific: 17 U/mg Streptavidin |
Reconstitution | Restore with distilled water or saline. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. We recommend that the vial is gently mixed after reconstitution. |
Preparation | Lyophilized Streptavidin from Streptomyces avidinii (Essentially salt free) |
Applications | Can be used for biotinylated antibody detection and quantification by ELISA, blotting and immunohistology; as a ligand for immobilization on activated matrices. |
Protein Description | Purified Streptavidin prepared by Affinity Chromatography |
Note | pI: 5 |
Storage | Store lyophilized at 2-8°C for 6 months or at -20°C long term. After reconstitution store the antibody undiluted at 2-8°C for one month or (in aliquots) at -20°C long term. Avoid repeated freezing and thawing. |
Stability | Shelf life: one year from despatch. |
Reference Data | |
Summary | 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. |
