Press Release Summary: AnaSpec has introduced a suite of fluorescently labeled GST
and 6X-His antibodies

Press Release Body: San Jose, CA - February 14, 2008

AnaSpec has introduced a suite of fluorescently labeled GST and 6X-His antibodies.
These antibodies are labeled with a selection of dyes, including AnaSpec's
proprietary HiLyte FluorTM and HiLytePlusTM dyes, which span the visible spectrum.
This gives researchers a wide range of wavelength choices for use in
immunohistochemistry or immunofluorescence applications. Non-labeled or biotin
labeled versions are also available.

Different gene expression systems have been used to produce recombinant proteins.1-2
Protein tags are peptide sequences genetically introduced onto a recombinant
protein. Tags include short peptides(FLAG, c-myc, 6X-His) or proteins
(glutathione-s-transferase - GST). This tagging technique aids in the
characterization, localization or purification of the recombinant expressed
protein.3 Antibodies raised against fusion-tags are useful in biochemical or
immunohistochemistry applications.
