Based on the high binding affinity between biotin-streptavidin systems, our Streptavidin series products are recommended to use together with biotinylated proteins to get lower non-specific binding results in a shorter time.
This protein contains a furin convertase cleavage site, 737-RKRR-740, and will be partially processed into N (α chain) and C-terminal fragment (partial β chain) with calculated MW of 81.0 kDa and 25.6 kDa respectively. The protein migrates as 45-50 kDa (partial β chain), 110-120 kDa (α chain).
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 . Normally Trehalose is added as protectant before lyophilization.
