Streptavidin conjugates are typically used as secondary reagents to detect biotinylated probes such as primary antibodies for flow cytometry, Western blotting, immunofluorescence staining and other applications.
Streptavidin conjugates are supplied in lyophilised solid format. After reconstitution with 0,5 ml PBS, streptavidin concentration is 2 mg/ml with 0,01% sodium azide. Monoclonal mouse anti-biotin antibody conjugates are supplied at 2 mg/ml in PBS pH 7,4 containing 50% glycerol, 2 mg/ml BSA (IgG-free and protease-free), and 0,05% sodium azide.
