Plasmid vectors are commonly used for the expression of hybrid fusion proteins, encoding a protein of interest fused to an epitope tag. Antibodies specific for such fusion protein tags are useful for monitoring expression of the protein of interest, both in cells and in Western blot analysis. Such epitope tags in common use include Myc, GST, His, HA, Flag and HN, etc. E-tag is one of novel series of epitope tags. It commonly applies to detect recombinant antibody with the tag. Anti-E-Tag antibody is suitable for purification, detection and immunoprecipitation of recombinant fusion proteins containing the respective E-Tag.

E-Tag antibody detects fusion recombinant antibodies derived from a variety of sources at various concentrations. No cross reactivity with other-tags-fusion protein was found in ELISA or Western Blot.

Store at 4°C if intended for use within one month, otherwise, store at -20°C to -80°C. The lyophilized antibody is stable for at least 18 months after the date of receipt when stored at -20°C to -80°C. After reconstitution, it can also be aliquoted and stored frozen at -20°C to -80°C in a manual defrost freezer for 6 months without detectable loss of activity. Upon reconstitution, the antibody can also be stored for 30 days at 4°C. Please avoid freeze-thaw cycles, as this will lower the activity of the antibody.
