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