Tag usually is a short peptide located on either the C- or N- terminal of the target protein. It could facilitate one or several of the following characteristics: solubility, detection, purification, localization and expression, so it is extensively used in the protein expression and function study in different fields. The monoclonal and polyclonal antibodies against the tags are useful tools for tracking the target protein. Genemay, Inc provides a full set of monoclonal and polyclonal antibodies against His-tag, Myc-tag, HA-tag, V5-tag, T7-tag, GST-tag, HSV-tag and Flag-tag, etc. These antibodies are ready to be used in the ELISA and western blotting applications.
