Anti-S Tag-HRP is a monoclonal antibody conjugated with horseradish peroxidase (HRP) that is specifically designed to recognize and detect the S tag. The S tag is a short amino acid sequence (KETAAAKF) that is commonly fused to the N- or C-terminus of a protein of interest to facilitate its purification and detection. Key Applications of Anti-S Tag-HRP: Western blotting: Used to detect and quantify the expression of S-tagged proteins. Immunohistochemistry: For visualizing S-tagged proteins in cells and tissues. ELISA: To measure the concentration of S-tagged proteins in biological samples.
