What are epitope tags? Epitope tags are small peptides that are fused to the protein of interest using recombinant DNA techniques. They make it possible to study recombinant proteins when protein-specific antibodies are not available or not suitable for your experimental design. Epitope tag antibodies are highly specific monoclonal and polyclonal antibodies for the detection and purification of the tagged proteins.
Sino Biological offers a full range of epitope tag antibodies with high-quality to satisfy researchers' need, including His Tag antibodies, HA Tag antibodies, Myc Tag antibodies, DYKDDDDK Tag antibodies, GFP Tag antibodies and V5 Tag antibodies, etc. All of these tag antibodies are fully validated in various applications, such as ELISA, Western Blotting (WB), Flow Cytometry (FCM), Immunoprecipitation (IP) and Immonofluorecence (IF).
