English Name: streptavidin from Streptomyces avidinii

Other names: streptavidin; Streptavidin; Chain affinity

CAS No.: 9013-20-1

Molecular weight: 62.4kd (tetramer)

Level: Biotechnology grade

Vitality: ≥ 14.0 units / mg

Properties (the following information is only for reference): white or off white freeze-dried powder, derived from Streptomyces. Users can use different buffers to dissolve it according to their own experimental needs. After dissolution, it should be stored at - 20 ℃.

Usage: This product is only for scientific research, not for other purposes. Streptavidin is a tetrameric protein, which has strong non covalent bond interaction with biotin, making this small molecule protein pair the most practical and widely used system in affinity labeling. Streptavidin can bind alkaline phosphatase or peroxidase. After binding to the biotin labeled oligonucleotide probe, the position of the target gene (DNA fragment) can be screened out by the chromogenic reaction at the band (spot) position after the carried enzyme interacts with the chromogenic substrate

Storage: 2 ~ 8 ℃
