Product Name:Streptavidin
English Name:Streptavidin
CAS No.:9013-20-1
Aliases:Streptavidin from Streptomyces avidinii, SA
Physical Properties:White or off-white lyophilized powder, derived from Streptomyces avidinii; soluble in water and common buffers; store at -20°C after reconstitution; tetrameric protein with a molecular weight of approximately 62.4 kDa, exhibiting extremely strong non-covalent affinity for biotin (Kd ≈ 10⁻¹⁴ mol/L).
Uses:Streptavidin possesses extremely strong non-covalent interaction with biotin, making it one of the most versatile and widely used systems for affinity labeling and detection. It is suitable for immunoassays, ELISA, Western blot, nucleic acid hybridization, and affinity purification. When conjugated to alkaline phosphatase or peroxidase, it can localize target genes or proteins through chromogenic reactions with biotin-labeled probes. For research use only.
Technical Specifications:
Activity: ≥14.0 units/mg
Molecular weight: ~62.4 kDa (tetramer)
Grade: Biotechnology grade
Appearance: White or off-white lyophilized powder
Storage: Store at 2-8°C; store at -20°C after reconstitution
Packaging: 1 mg, 5 mg, 25 mg, 100 mg, 250 mg
