+<H2>Description</H2>
+
+<p> This track shows potential enhancers whose activity was experimentally validated in transgenic mice.
+Most of these noncoding elements were selected for testing based on their extreme conservation in
+other vertebrates or epigenomic evidence (ChIP-Seq) of putative enhancer marks. More information
+can be found on the <a href="http://enhancer.lbl.gov" target="_blank">VISTA Enhancer Browser</a>
+page.
+</p>
+
+<h2> Display Conventions and Configuration </h2>
+<p> Items appearing in <b><font color="red">red</font></b> (positive) indicate that a reproducible
+pattern was observed in the in vivo enhancer assay. Items appearing in
+<b><font color="blue">blue</font></b> (negative) indicate that NO reproducible pattern was observed
+in the  in vivo enhancer assay.  Note that this annotation refers only to the single developmental
+timepoint that was tested in this screen (e11.5) and does not exclude the possibility that this
+region is a reproducible enhancer active at earlier or later timepoints in development.

+<h4>Enhancer Candidate Identification</h4>
+<p> Most enhancer candidate sequences are identified by extreme evolutionary sequence conservation or
+by ChIP-seq.  Detailed information related to enhancer identification by extreme evolutionary
+conservation can be found in the following publications:

+<h2>Data Access</h2>
+<p>
+VISTA Enhancers data can be explored interactively with the
+<a href="../cgi-bin/hgTables">Table Browser</a> and cross-referenced with the 
+<a href="../cgi-bin/hgIntegrator">Data Integrator</a>. For programmatic access,
+the track can be accessed using the Genome Browser&apos;s
+<a href="../../goldenPath/help/api.html">REST API</a>.
+ReMap annotations can be downloaded from the
+<a href="https://hgdownload.soe.ucsc.edu/gbdb/$db/vistaEnhancers">Genome Browser's download server</a>
+as a bigBed file. This compressed binary format can be remotely queried through
+command line utilities. Please note that some of the download files can be quite large.</p>
