Strep tag Antibody (910STR) in WB
Western blot analysis of E. coli lysate containing Strep-tagged protein with anti-Strep-tag antibody. Western blot analysis was performed on 80 ng, 40 ng, or 10 ng of E. coli lysate containing Strep-tagged protein. Cells were lysed with SDS sample buffer. The PVDF membrane was blocked with 5% dry milk in PBST for 1h at RT. The primary antibody anti-Strep-tag mouse monoclonal, C23.21 (Cat. No. 910STRL) was diluted in blocking buffer (antibody concentration 0.02 µg/mL) and incubated for 1h at RT. The secondary antibody goat anti-mouse IgG po... View More

Product Specific Information
Reconstitute with 250 µL PBS.
Specificity: Strep II. A Step-tag is commonly added to recombinant proteins and can be used for detection or purification of the tagged protein.
Target Information
Streptavidin is a tetrameric protein purified from Streptomyces avidinii 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.
