Anti-S1 Tag Antibody

The Anti-S1 Tag Antibody from Antibodies.com is a mouse monoclonal IgG1 reagent raised against the S1 peptide epitope, a short affinity tag commonly fused to recombinant proteins to enable purification and tracking during expression. Supplied as 100 µg of liquid antibody in an unconjugated format, the reagent is validated for western blot detection of S1-tagged fusion constructs expressed in standard host systems such as E. coli. The S1 tag's compact size makes it a useful alternative to larger affinity tags when minimal perturbation of the target protein is desired. For handling, store the vial at -20 °C in single-use aliquots and avoid repeated freeze-thaw cycles to preserve antibody activity over the product's shelf life.
