Probe Maps

The probe maps throughout this website and in the 2017-2018 version of the Cytocell catalogue have been updated to include information on gene orientation to allow the 3’ or 5’ positions of the probes to be seen in relation to the gene, or region, of interest. The arrows on the genes indicate the direction of transcription. Those with an arrow above, pointing to the right, are located on the plus, or sense, strand of the DNA. Those with an arrow below the gene, pointing to the left, are on the minus, antisense strand. In both cases, the 5’ end is that with the arrow, as genes are transcribed in a 5’ to 3’ direction. Examples can be seen below.
